We remove unpleasant odor from the sink in no time: folk and traditional methods. How to remove odor from a sink? How to eliminate odor from your kitchen sink

The “aroma” of sewage, especially in the place where food is prepared, evokes the most negative emotions. Therefore, eliminating odor from your kitchen sink becomes a top priority. There can be several sources at once, and therefore the methods of disposal are different. His choice depends on the cause of the problem. It is necessary to check the sewer and siphon, and use a cable, plunger and cleaning products to eliminate the smell.

Causes

The sink is a place where all kinds of debris accumulate: food debris, oil, hair. Compressed into one ball, they become a source unpleasant odor. This happens as a result of malfunctions in sewer system.

A siphon is part of any plumbing fixture. It can be made of brass, plastic or other material, and is available with a membrane or dry water seal. Thanks to the curved elbows, the device forms a water plug, which clogs the air from the sewer, preventing it from entering the bathroom or kitchen.

The siphon has several functions:

• Eliminating unpleasant odors from sewer pipes.
• Protection against blockages. This is a filter and storage tank for large debris, which can be easily removed by opening the siphon.
• Ensuring self-flow of wastewater into the sewer system.

There are two main causes of unpleasant odor:

Incorrect installation of siphon and corrugation

1. In this case, water flows out of the water seal. If the height of the pipe is not sufficient, bad smell occurs in 100% of cases. Adjusting it to a standard of 3 cm below the water line solves the problem.
2. Errors may occur when installing the corrugation. If you forget to install a water seal, the water goes directly into the drain or retrogradely returns to the sink.
3. Sagging or stretching of the pipe is associated with incorrect operation of the special clamp that supports the S-shaped corrugation structure.

Long downtime

The water in the siphon may evaporate if the washbasin has not been used for some time. As a result, an unpleasant odor appears. You can eliminate this by filling the sink with water and waiting for it to drain, then creating a film of vegetable oil(a few tablespoons) by simply pouring it into the drain. If a smell appears, repeat the procedure.

Other reasons

Blockage (one of the most common reasons), dirt in the flask, incorrect installation of pipes, low-quality components. The first ones can be easily eliminated with a plunger, soda, vinegar or special means such as Mole, etc. We will talk about this in more detail below.

If your independent searches do not produce results, or you find incorrect installation of pipes, etc., you need to contact a plumber. Finding the cause and eliminating it is fundamentally important. The stench is dangerous, as ammonia and hydrogen sulfide negatively affect the bronchi and lungs.

How to find a fault?

Logically, this is a matter for a plumber. But such help costs time and money. If you can’t cope with emergency situations without professionals, then you can try to fix minor problems yourself: flush the system hot water with special means, disassemble and clean the siphon. You can detect cracks or chips, leaky joints, and seal defects. Defective parts must be replaced.

How to remove an unpleasant odor?

There are several ways to eliminate it.

Cable

A regular metal cable is not suitable. You need a special one, plumbing, at least 5 meters long. It is equipped with a brush or hook that can lift the clog. The handle is also specific: it allows you to rotate the cable.

To remove a garbage plug this way, you should:

• Clear access to the corrugation.
• Insert the cable into it to the maximum depth.
• Start “screwing” it with your hands until it reaches the blockage.
• Use a hook to pull out the debris or push the plug further.
• You can try to break up the blockage with a cable, moving it in different directions.

After manipulation, wash the cable and lubricate it machine oil. Then roll it up and put it away.

plunger

It is used if you are completely sure that the siphon is clogged and there is no desire to disassemble it.

Necessary:

• Place the plunger cap over the drain and, opening the hot water tap, wait until it completely covers it.
• Close the tap and forcefully move the plunger up and down, then sharply pull it out along with part of the blockage.
• Turn on hot water and rinse the sink.

If you don’t have a plunger at home, you can repeat the same steps using a milk or juice carton, cutting off the top of the package.

They disassemble the siphon only if they are completely sure that it is the cause of the unpleasant odor. The test will be the following procedure: you need to pull the corrugation out of the riser, lower it into a container, turn on the water and see if there is a leak. If it is missing, the siphon is disassembled and cleaned:

• First unscrew the bottom part. If this is not the problem, continue disassembling.
• Remove all nuts and carefully inspect the pipes.
• Remove the blockage.
• Rinse the siphon.
• Putting all the parts together.

When assembling, be sure to use the instructions; if you followed them, the sink should work normally.

Cleaners

They can be from improvised products or professional ones. The most popular:

• Salt. The whole glass is poured into the sink and filled with half a liter of boiling water. After 3 hours, hot water opens and the entire drain is washed.
• Soda with salt. The mixture is prepared in a 1:1 ratio, after which it is also poured into the drain. After half an hour, it is washed with boiling water and the procedure is repeated. If this does not help get rid of the smell, then another cleaning method is chosen.

• Vinegar with soda. Proportions: pour two large spoons of soda into the siphon and then pour a glass of vinegar there. The drain is closed with a stopper, and 10 minutes after the end of the reaction, it is thoroughly washed with boiling water.
• Concentrate sachet citric acid in powder form, pour into the drain and turn on hot water. A reaction like vinegar and soda begins. The further algorithm is the same. Dry mustard can be a substitute for lemon powder.
• TO professional means chemicals for cleaning pipes include: Mole, Domestos, Brawl, Odorgon, Mister Muscle, Sanox, Whiteness. To rinse the siphon, you must follow the instructions and take into account that the powder is more active than the liquid.

Prevention

You can not only get rid of unpleasant smell from the sink, but also prevent it if you strictly follow simple rules:

• Clean the sewer pipes not only when an odor appears from the sink, but also regularly (monthly). Salt and soda should be used once a week. This sequence of processing allows you to maintain the relative cleanliness of plumbing fixtures.
• Never flush leftover food and tea leaves down the kitchen drain. They are the ones who clog the siphon.
• When going on vacation or a long business trip, you should take care of the condition of the plumbing by pouring oil (vegetable or machine) into the siphon. Volume – small glass. This will help avoid evaporation of moisture and drying out of pipes, which gives off a sewer “aroma.” When you return, you just need to flush the drain warm water With detergent.
• If it is necessary to replace pipes or a siphon, you should entrust the work to a specialist.
• Choose new plumbing should also be a professional. You need to focus on ease of use and quality. It would be better if the siphon is removable. This does not require complete dismantling of the pipes for cleaning.

If there is a smell from the sink in the bathroom, it means there is a problem in the sewerage units. To understand how to get rid of smell, you need to have an understanding of the design of utilities.

The structure of the spillway is based on the interaction of the siphon and the water seal. The interconnection of these sewerage elements helps to retain and renew the amount of liquid in the siphon elbow. This holds back the flow bad smell from the sink. Fan ventilation provides correct work siphon.

Externally, the water seal looks like the letter U. This shape helps to keep water at the same level according to the principle of communicating vessels. The water seal plays the role of a lock that prevents odors from entering the room.

Siphons are divided into two groups:

• corrugated;
• flask

Corrugated siphons have become widespread due to their low cost. However, the service life of plastic products is 2 times less than metal ones.

Flask siphons are recognized as the most convenient for self-diagnosis by the householder. Collapsible design includes removable elements that can be easily disconnected without disassembling the water supply network.

Causes of odor

Flow dirty water leaves a coating of grease and dirt on the pipe walls. Over time, the layer rots and smells bad. If the operation of one sewer unit (hydraulic seal or pipeline) is disrupted, fragrance enters the apartment.

Sources associated with siphon malfunctions:

1. There is no water in the siphon. This happens if the siphon is positioned incorrectly. For example, a plastic outlet is installed above the water level. In this case, the height of the inlet pipe is adjusted. The standard penetration of the tube into the liquid is 2–3 cm. In this case, the outlet does not rest on the bottom of the hydraulic lock. Another common installation error is depressurization of the joints of the waterworks. In this case, dismantling of the equipment with complete reinstallation of the links is required.
2. Dry siphon. The lack of liquid in the siphon is due to the fact that the washbasin has been idle for a month or more. Experts recommend it as a preventive measure sunflower oil in the amount of 50 grams, poured into the drain. The resulting film will protect the water seal from water evaporation. To begin full operation after a break drain design washed with a stream of water.
3. Corrugation sagging. The factory equipment includes clamps and clamps that protect the corrugated part from sagging. If the corrugation sag, the set is dismantled and replaced with a new one.

Other sources of odor

The blockage can be removed using a plunger or plumbing cable. Additionally, the flask is removed and washed.

Damage in the pipeline. Even an improperly secured sewer pipe can lead to trouble. Checking the fastenings and integrity of the surface of the pipes will help to detect and eliminate the area that stinks and remove the putrid odor.

Depressurization of connections. If there is a leak in the area, it means that errors were made during installation. Depressurization is possible due to worn-out equipment. The detected defect is removed after disassembling the unit, washing, drying the parts and treating the connections and joints with silicone sealant.

Riser. Impaired water circulation in the circuit can cause air lock in the knees of a riser. Occurs as a result of reduced pressure inside the circuit. It is impossible to remove a defect that has arisen on your own. Inspection of general building utilities is required.

Ways to eliminate odors

The topic of odors from bathroom sinks and ways to get rid of them is always relevant. The smell of sewage is harmful to human health. How to eliminate an unpleasant smell from a sink and what to do before the plumber arrives?

First of all, observe the drain rate in the sink. To do this, a strong pressure is turned on. Slow drainage indicates a blockage.

The chemical industry offers a wide range of drugs to combat blockages. Three types of medications will help get rid of blockages:

• dry;
• liquid;
• gel-like.

The general similarity is in their contents: the basis is caustic substances such as sodium and/or chlorine. When using such products, strict adherence to instructions and compliance with safety rules is required. After getting rid of the plug, it is recommended to thoroughly flush the system. “Domestos”, “Mole”, “Tiret” are universal compositions designed for use in working with all types of materials.

According to user reviews, it is effective new development Israeli chemists in Bagi Pothan granules. The product completely dissolves blockages of any complexity. At the same time, the manufacturer draws attention to the need to comply with all safety requirements, including enhanced ventilation of the room.

“Whiteness”, soda ash, dry bleach, poured into the sink, are able to cope with a small blockage. Inexpensive but effective substances can be used for prevention.

After cleaning the sink, the drain is flushed with high water pressure.

Plastic does not contact everyone chemical compounds. When buying a substance to get rid of a blockage, pay attention to the restrictions on use.

Folk recipes

Getting rid of stench using folk remedies:

• Extinguish 3-4 tablespoons of baking soda with a liter of hot water and pour into the drain hole. After 1 hour, rinse the drain with boiling water
• baking soda mixed with vinegar in equal parts. The resulting mixture is poured into the drain. After 30-40 minutes, rinse with hot water;
• Dry mustard poured into the sink pipe and poured boiling water will eliminate the foul odor.

An undoubted advantage of using traditional methods in their environmental friendliness. The action of alkali and acid is aimed at eliminating harmful bacteria without causing harm environment. In addition, this is a serious savings in household finances.

When the kitchen smells like sewage, it causes a lot of inconvenience and is unsafe for health. The aroma intensifies over time, spreading throughout the apartment. Need to know possible reasons the occurrence of odor from the kitchen sink, how to eliminate it and prevent its reappearance.

An unpleasant odor appears in the kitchen sink.

Causes of unpleasant odor

Required element drain system The sink is a siphon - a device made of metal or plastic, the design of which ensures that it retains a certain amount of water drained into the sewer. This creates a water barrier that prevents sewer fumes from entering the room.

If you don't install a siphon under the sink, the kitchen will soon smell like sewage. The same will happen in case of incorrect installation of this element or its mechanical damage.

Other causes of stink:

1. Formation of blockage. Fat, food debris, and viscous components fall into the drain, which are layered on the walls of the pipes and settle in the siphon. They create a breeding ground for putrefactive bacteria, the activity of which results in an unpleasant odor spreading throughout the kitchen.
2. Evaporation of water barrier. This happens when the sink is left inactive for a long time.
3. The appearance of an air lock in the system. Air occupies part of the diameter of the drain pipe, interferes with the drainage of water, causing its jerky passage with a characteristic gurgling sound. It partially comes back, which causes the stench. Reasons for airing: blockages, depressurization of components, errors in planning or installing sewerage.
4. Corrugation stretching. This pipe is deformed under its own weight and the influence of hot water, which can lead to both the return and stagnation of liquid in the sagging part, and to the complete drainage and disappearance of the hydraulic barrier.

The smell appears not only due to the ingress of air from the sewer into the kitchen, but also due to the seepage of wastewater when the tightness of the drainage system is broken, for example, when the gasket at the joint is thinned or the pipe is mechanically damaged.

You can get rid of the stench only by identifying and eliminating the cause of its occurrence. In most cases, you can correct the situation yourself by manually cleaning the sewer, using specialized household chemicals or improvised means.

Mechanical elimination methods

First, you should disassemble and clean the siphon. If the blockage is not found here, it may be located elsewhere. To eliminate it, use a plunger or a special cable. After cleaning, the sink must be treated with a disinfectant.

Steel rope

When the clog is located far from the kitchen sink drain hole, it will help to remove it plumbing cable, at the end of which there is a hook, fixed metal brush or other suitable attachment. For plastic pipes It is recommended to use a device with a rubberized braid.

Cleaning a sink with a steel cable.

Work order:

1. Disconnect the corrugated element. Direct the end of the unfolded cable into the opened hole and push it as far as possible towards the riser.
2. Rotate the handle in one direction and gently push it down the pipe until it hits the dirt plug.
3. Continuing rotation, try to insert the cable even deeper. If this fails, you need to pull it out a little, then rotate and push it again.
4. Sometimes the cork or part of it can be removed by picking it up with a hook located at the end. Therefore, the cable is periodically completely removed, inspected and cleaned, and then reinserted into the pipe.
5. When the area can be easily traversed, the device is removed, washed and wiped dry. The corrugation is connected, the drain is washed abundantly with hot water.

All manipulations are performed with caution. Not only blockage, but also the design features of the system (bending, joint) can interfere with the free passage of the cable. The force can break the seal or damage the inner surface of the pipe, making it easier for solid particles to take hold.

plunger

If a characteristic smell appears and the water in the sink does not drain well, the reason is most likely that the siphon or the pipe connected to it is clogged. You can clean them with a plunger. Place it in the sink and press it tightly, making sure that the rubber nozzle completely covers the drain hole. Now you need to draw a little hot water and make several vigorous movements, alternately pressing on the handle from above and loosening the pressure, then sharply remove the plunger from the drain.

The steps are repeated several times until the blockage is cleared, after which the remaining dirt deposits are washed off with a stream of hot water. You can clean a bathtub or washbasin in the same way, but you need to cover the overflow hole with a rag or tape.

Chemicals

When your kitchen smells like sewage, you can use chemical cleaners. They not only remove unpleasant odors, but also eliminate blockages, dissolve fatty deposits, and disinfect drains. They contain caustic and toxic components, therefore, when in contact with them, you must protect your eyes, respiratory organs and skin of your hands, and after use you must thoroughly ventilate the room.

They come in the form of liquid, granules, powder or gel. Powder products are characterized by increased activity, and gel products are the safest for human health and elements of the drainage system.

1. Mole. Inexpensive, effective cleaner. Available in liquid, gel and granular powder form. Deletes different kinds dirt, including hair, but it works slowly.
2. Tiret. A gel product used primarily for preventive cleaning. The Turbo variety is more effective and acts quite quickly, but is unsafe for copper and rubber parts. Does not always cope with complex blockages.
3. Floop. Granules that are activated by hot water. A powerful product that removes dirt plugs in just a few minutes. May damage thin plastic.
4. Mr Muscle. Produced in granular and gel forms. Suitable for all types of drains. Sometimes the result appears after a few hours.
5. Sanox. A soft, inexpensive product in the form of a gel. It works slowly and does not give off a heavy odor. Doesn't always help.
6. Deboucher. Liquid for cleaning drain pipes, safe for enamel and plastic parts. It acts quickly; for complex stains, the activity time is extended.
7. Pothan. One of the most expensive drugs. It comes in the form of granules. Copes with difficult blockages, which as a result of a violent reaction can rip off the pipe, deform or corrode thinned plastic.
8. White. The liquid will help remove odors and disinfect drains, but it will not cope with complex contaminants.

Cleaning the sink chemicals.

After applying the chemicals, the softened residues are washed off with a stream of hot water, leaving the tap open for 15-20 minutes.

Traditional methods for cleaning pipes

The means at hand are non-toxic and safe for drains. They will help get rid of unpleasant odors and clear small blockages.

Soda

Cleaning sinks with baking soda.

Baking soda is a good degreaser and has antibacterial properties, so it can help remove odors from your sink. The sewer system is first cleaned using a plunger.

Half a glass of the product is diluted with boiling water in a ratio of 1:3, the mixture is poured into the hole and left for 30 minutes. If the result is weak, the procedure is repeated.

To combat blockages, soda is used in a mixture with vinegar (1:1). It is recommended to heat the latter slightly with the hood on.

First, pour at least 150 g of bicarbonate powder into the sink hole, then pour in vinegar and close the drain with a stopper or rag. After half an hour, the pipe is washed with several liters of boiling water, then the hot water tap is left open for 10 minutes.

Salt

This product has good cleansing properties, including removing grease and eliminating unpleasant odors.

Mode of application:

1. Dissolve 0.5 cups of salt in 2 liters of boiling water.
2. Pour the liquid into the sink. Leave for several hours.
3. Rinse thoroughly with a stream of hot water.
4. If necessary, repeat the procedure.

Salt is often used in combination with equal amount baking soda or mixed in a 1:2 ratio. The mixture is placed in the drain and poured with a small volume of boiling water. It is better to do this at night, because the sink cannot be used for 8-10 hours. The drain will need to be flushed in the morning.

Dry mustard

Mustard powder is effective in combating fat deposits and unpleasant odors from the sink. It is enough to add 2-3 tbsp. l. mustard and pour 1 liter of boiling water over it. After 20 minutes, the drain is washed. If there is a blockage, this method must be used with caution so as not to aggravate the situation.

Dry mustard to clean the sink.

Preventive measures

To prevent sewer smell, you should:

• install a siphon under the sink rather than connecting the drain directly;
• use special mesh filters for the sink to prevent solid particles from entering the drain;
• flush the pipes regularly with hot water and soda solution to eliminate fat;
• periodically inspect components for leaks and repair them.

If the sink will not be used for a long time, it is recommended to pour a little vegetable or machine oil into the drain hole. This will protect the hydraulic barrier from drying out, and sewer gases will not penetrate into the room. In the future, the drain will need to be degreased.

The bathroom is a place that is traditionally associated with cleanliness; it is there that we cleanse our bodies of dust. big city, and your head from unpleasant thoughts and worries. However, sometimes a repulsive, fetid aroma of sewage can spread throughout this room.

The first reaction of the housewife, who realized that the inside of the bathroom did not smell like flowers, was to wash everything she could with a strong detergent. However, if this measure saves, it is temporary, and sometimes it does not bring any result at all. In this article, we will tell you how to remove smell from your sink so that it never comes back.

What causes sink odor?

Unpleasant smell from the sink - serious problem, which not only violates sanitary and hygienic standards, but also annoys any housewife. There are many reasons.

Through which sewer “odors” can escape and fill the room with a stench. Most often, an unpleasant odor in the bathroom is caused by:

Important! If the cause of the unpleasant odor lies in high humidity premises, then the system will help to remove it forced ventilation. Fresh air It will dry out the room and also remove sewer odors.

Sewage problems

The bathroom contains many plumbing fixtures: a bathtub, a washbasin or sink, a toilet, washing machine. All these devices are connected not only to the water supply, but also to the sewerage system.

If during installation the sewerage system is connected to plumbing equipment with technical errors and flaws, an unpleasant odor may arise from the bathroom sink. The most commonly diagnosed problems with the sewer system are:

Note! Any defect in the installation of a sewer system in a bathroom, be it an incorrectly selected pipe cross-sectional diameter, poor sealing of joints, or an incorrectly set slope, is fraught with an unpleasant odor. Therefore, it is important that the pipes are laid experienced master, which will take into account all these nuances.

How does a water seal work?

Every plumbing fixture that is used in the bathroom and connected to the sewer system has a siphon. A siphon is a special device that does not allow foreign odors to penetrate from the sewer pipe into the room. It is made of brass, plastic or other material.

There are models of siphons with a water seal, a membrane seal and a dry seal. Thanks to its special curved shape with one elbow, this device creates a water plug inside that prevents air from the sewer pipe from entering the sink or bathtub. Siphons perform the following functions:

1. Removes unpleasant odors that may enter the room from the sewer pipe. While the plumbing fixture is being used and the water in the water seal does not dry out, air from there cannot penetrate up the pipe.
2. Protects against sewer blockages. They filter out large debris that ends up in your sink or bathtub drain. All large impurities fall into the siphon sump, after which it can be removed from there.
3. Sewage is directed by gravity into the sewer system. The shape of the siphon is such that through the drain waste water easily flows into the sewer without stagnating at the bottom of the sink or bathtub.

Please note that the water seal only works until the water in it dries out. Therefore, when no one uses a plumbing fixture for a long time or there is no water supply for a long time, the liquid in the siphon dries out, which is why there may be a sewer smell in the bathroom.

If the reason that the bathroom smells is because the water seal has dried out, then the easiest way to deal with this problem is to simply fill the siphon with water and thoroughly ventilate the room.

How to deal with the problem?

Many housewives are wondering how to eliminate the smell from the sink in the bathroom, how to get rid of the persistent aroma of the sewer, if a sponge and detergent no longer help.

If the bathroom is cleaned regularly and thoroughly, but the odor is still present, then the problem is most likely in the sewer system, so we will deal with it. To get rid of sink odor, follow these instructions:

Remember! We clean the bathroom quite often, because keeping it clean is not easy. However, we often forget that the pipes and siphon need to be cleaned periodically so that no unpleasant odors bother you. In addition, it is necessary to carry out preventive measures: you should not throw cleaning materials, garbage, grease into the sink, you need to clean the siphon sump and change the corrugation on time.

Video instruction

It seems that all hygiene rules are being followed, but the sink still emits unpleasant sewage odors from time to time. And it’s not always possible to get rid of them - without knowing the cause, it’s difficult to eliminate the consequences.

Before you figure out why your sink smells like sewer, you should have an idea of ​​how the system works. All plumbing fixtures (bathtub, toilet, sink, washbasin) are drained into one general sewerage, passing along all floors of the riser, which has an exhaust hole in its upper part.

Check and replace, if necessary, sink drain pipes

All sanitary fixtures in the area before entering the sewer pipe have a special siphon in the form of a curved elbow, the main function of which is to hold the water seal. This water plug in the elbow prevents odors from the pipes from entering the room.

The main reason for the stench in the kitchen is problems with the water seal:

• The knee may not be positioned at the correct angle or height.
• If the siphon is made of corrugation, then over time it loses its shape.
• The device had not been cleaned for a long time, and residual grease had accumulated on the walls.
• If the sink has not been used much, the water in the seal may evaporate.
• Moisture also evaporates if heating pipes pass under the sink.

Another reason why an unpleasant odor may appear in the kitchen is due to flaws in the installation of the system. Poor sealing of pipes and incorrectly selected cross-section diameters will be the culprits in the penetration of sewer odors into the kitchen.

General sewer It is no coincidence that the sewer system has access to the attic of the house - this is necessary for ventilation of the system and removal of sewer aromas to the outside. Sometimes residents top floors during repairs, they simply remove the extra (in their opinion) section of the pipe, thereby blocking the exit. It is not surprising that the smells will spread throughout all the apartments of the riser.

When your sink smells like sewer, what to do and what not to do becomes a pressing question. But you definitely don’t need to grab an air freshener: it won’t kill the stench, and it won’t remove it. It is necessary to look for the cause and eliminate it.

To do this, an audit of the entire system is carried out to eliminate malfunctions, leaks, and depressurization. The main attention should be paid to the water seal. To do this, it is advisable not only to inspect the siphon from the outside - it should be temporarily dismantled to check for blockages.

It is better to replace the siphon made of corrugated material with a new one. Do not try to return the old device to its previous state - this is a temporary measure, because... a deformed corrugation, even on wire hangers, will poorly retain water in the seal.

It is enough to clean siphons made of other materials (plastic, metal) from the inside if they are not damaged. When reinstalling, check the correct slope, the height of the pipe and the ratio of pipe diameters. The joints should be reliably sealed.

checking the water seal system

But you should not connect the sink directly to the sewer by removing the water seal elbow. Without a siphon, the smell will penetrate even more into the premises, becoming persistent.

If the cause of the smell is faulty installation of the sewerage system, do not try to eliminate it yourself - entrust the work to an experienced plumber. As in the case when the neighbor above cut off part of the sewer pipe, let a specialist solve the problem.

Sometimes, in order to find the answer to the question of how to eliminate the smell from the sewer in the kitchen, it is not necessary to immediately unscrew the siphon. First you should try chemicals to clean the drains - maybe the reason is just that the drain is clogged with greasy waste.

The following products have a good cleaning effect: Domestos, Mole, Deboshir, Odorgon. Use them according to the instructions on the packaging, observing all safety measures (these chemicals are toxic). Sometimes it is enough to use a solution of bleach or bleach.

The drug is poured into the sink and after a certain time is washed off with copious amounts of water. If one time is not enough, you can repeat the procedure after a couple of days. But if this doesn’t help, then start dismantling the siphon.

cleaning the pipe without removing it with chemicals

Chemicals may not always be at hand, and the stench becomes intrusive. How to get rid of sewer smell in the kitchen in this situation? Some food products may be useful as a disinfectant:

• Table salt (preferably rock salt) is poured into the sink drain hole and the plumbing is not used for 3 hours. The pipes are then washed with plenty of water.
• Baking soda poured into the pipe will also work. Next, add table vinegar and leave for half an hour. In this case, it is advisable to cover the drain hole with something so that foam does not come out (a derivative of the reaction of soda with vinegar).
• You can also use dry mustard - it will both clean the sewer pipes and block the unpleasant odor.

Washing soda can also help. It is first filled with boiling water and immediately poured into the sink drain hole. But the procedure must be carried out carefully, because... the reaction will occur instantly, and the bubbling solution may harm you.

regular cleaning of pipes and checking the elbow for blockages

The smell of sewage from the sink can be avoided if you follow some rules for caring for your plumbing:

• The drain cleaning procedures described above should be carried out not only when a persistent smell appears from the sewer. It is necessary to clean the drain (and not just in the kitchen sink) at least once a month. And salt or soda can be used even more often - once a week. This will keep the pipes relatively clean.
• Do not throw leftover food, tea leaves, etc. into the sink. Their small particles, having penetrated the siphon (especially if it is corrugated), clog it, preventing the water seal from functioning normally.
• When going on vacation, take care of the condition of the water seal so that you are not surprised by a foul smell when you open the apartment door. Oil (vegetable or machine oil, it doesn’t matter) will help slow down the evaporation of water in the siphon. Pour it down the sink drain (about a shot glass) and drive away quietly. When you return home after relaxing, rinse the system with warm water, using a pre-cleaning agent.
• If there is a need to replace the siphon or other sewer pipes, you should not invite a neighbor or friend who has little knowledge of plumbing work. To avoid any complaints, entrust this task to a specialist.
• When choosing a new siphon, do not rely on the advice of inexperienced people and do not rely on the price of the product. The main argument should be quality and ease of use. If further maintenance of the siphon is expected on our own, it is better to buy the flask version (it is also called barrel-shaped). There is a special, easily removable element that allows you to clean the siphon without completely dismantling it.

If the appearance of sewage smell from the kitchen sink is not always the fault of the apartment owners, then eliminating it depends only on them. Maintaining basic hygiene while conducting preventive measures, without relying only on your (sometimes illiterate) abilities, without saving on money, the stench can be, if not completely avoided, then actually reduced.

We encountered an unpleasant odor from the sink after replacing the siphon. It turned out that they were screwed too low, the tube did not reach the water level in the flask. Everything can be easily unscrewed and tightened there, you can try it yourself. We twisted it higher and the smell disappeared.

The same is true in the bathroom; a special bend in the corrugated tube provides a water seal. If this is not done, the smell of the sewer will gain access to the apartment.

A good tip is to periodically flush the siphon. It was also an experience. If food remains accumulate there, they begin to decompose over time, the smell becomes stronger and stronger, pouring hot water does not help. The best thing is to unwind and rinse.

I try to use mustard as a disinfectant; I almost always have it in the house.

A fairly common and extremely unpleasant problem is the smell from the kitchen sink. How to eliminate it and what to do if a stench appears? You will learn the answers to these questions from the article.

Why might the kitchen sink smell bad? An important part of this piece of plumbing is the siphon, which is a curved tube with a container - a water seal or lock.

Modern kitchen sink can be equipped with several types of siphons. The first is flask, bottle or barrel-shaped. In its lower part there is a container in which water accumulates. The second type is corrugated. It is a soft, curved, corrugated tube, fixed in a certain position and creating a space for fluid accumulation. The third type is a knee siphon, which has several connected pipes in its design, one of which forms a bend and retains part of the water.

Since the function of preventing the spread of unpleasant odors is performed by the siphon, it is problems in this part of the sink that provoke the occurrence of stench. The reasons for its appearance may be the following:

1. Wear of some parts or their untimely replacement. For example, if the corrugated tube stretches too much and sag, it will not be able to cope with the flow of water and ensure that it is directed correctly. Corrosion of some parts of the sink can also lead to unpleasant odors.
2. If there is a rotten smell, then perhaps the process of rotting has begun in the siphon. It may be caused by food residues getting stuck in this part and decomposing. For example, if hair gets into the siphon, it can form a lump that will interfere with normal drainage and cause stagnation of particles entering this area. The same situation can arise when foreign objects get stuck in the siphon: rags, matches, sponges.
3. Clogs are another common cause of unpleasant odors. They can occur due to the accumulation of insoluble food particles or fat in the pipes or siphon. This often happens if the dishes are poorly cleaned before washing and washed cold water, especially without detergents.
4. The smell from the sink drain may be due to improper installation of the siphon. If it was carried out independently and with errors, then this element will not be able to fully perform its functions.
5. If the plumbing smells like sewage, then the sealing of the pipe joints is probably broken.
6. Damaged pipes. If there are chips or cracks on their walls, then water can seep out through them. Because of this, it will not reach the siphon in required quantities and will begin to fall on the floor or walls, causing mold to appear, which can also smell unpleasant.

To get rid of unpleasant odors caused by incorrect installation of the siphon, you need to achieve it correct design. Corrugated elements are often installed, and their main disadvantage is rapid wear, which leads to the loss of the necessary curved S-shape. To restore it, you need to create a bend and fix the pipe in this position using specialized clamps, electrical tape or tape.

Another common type of siphon is flask siphon. The main mistake when installing it is incorrect installation pipe If it does not reach the water in the siphon flask, then unpleasant odors are inevitable. In this case, you need to reinstall the pipe so that it is at least two to three centimeters deep in the water, or even better, it almost reaches the bottom of the container.

To remove the odor caused by a clog, you need to unclog your sink drain or trap. This can be done in different ways:

• Plunger. Many people have this device, and it is quite simple to use. Place it in the sink so that the rubber bowl completely covers the drain and rests against the bottom of the sink. To ensure reliable fixation, you can dial not a large number of water. Then press the handle firmly to create a vacuum in the rubber part, and then sharply pull the plunger up and give several active pushes. If the blockage is not cleared, repeat the procedure.


• Try using a plumber's rope. Place its pointed end in the sink drain and, turning the handle, begin to push the device further: into the siphon and pipes. Then push it back and forth to remove the blockage and clear the pipe walls. Remove the cable, clean it and, if necessary, repeat all manipulations.
• If you have a small diameter garden hose, that will also work. Connect it to the faucet, place the end in the drain and wrap it in rags so that the water cannot come out. Next, turn on the hot water under high pressure: the jet will break through the blockage and push it into the sewer.

What should I put in to stop the smell coming from the sink? Household chemicals will come to the rescue. There are many specialized products on sale for removing blockages in plumbing, such as Tiret and Krot. They are poured into the drain hole and left for a while, and then thoroughly washed with hot water.

To eliminate unpleasant odors, you can use folk remedies:

• Soda will help. Pour one glass of it into the drain hole, and then pour boiling water or very hot water. You can replace the water with 9% table vinegar, which will begin to extinguish the soda and start chemical reaction, helping to dissolve blockages and clean pipes.


• You can eliminate smell from the sink at home using finely ground salt. It is poured into the drain (about a glass), left in it for several hours, and then washed with hot water. If the situation does not return to normal, the procedure can be repeated.
• If your sink stinks, try using lemon juice or acid dissolved in water (a glass with a large spoonful of powder). Pour the liquid into the drain and wait a while, then turn on the hot water. Lemon juice will not only help clean the pipes, but also eliminate unpleasant odors.

Sink stench can occur due to prolonged periods of unused plumbing. The water will completely evaporate and will no longer form a seal and retain odors penetrating from the sewer. This happens if residents are absent from home, or the housing is not used at all.

Solving the problem is simple: just drain the water to clear the drain, remove the smell into the sewer and form a water seal. To make these measures more effective, use hot water with a pleasantly scented detergent added.

The cause of the spread of unpleasant odors may be a leak. In this situation, water will leak out and leave the siphon (because of this, it may stop working properly), and also get on the walls and floor, causing the formation of mold, which also smells bad.

What to do if a leak occurs? You just need to replace the leaky part or part. But if the common riser starts to leak, you will have to turn to a plumber for help, since you definitely won’t be able to change the pipe yourself, or you will do it incorrectly.

To prevent the appearance of unpleasant odors from plumbing in the kitchen or bathroom, you need to follow preventive measures:

• If you plan to leave for a long period, you can ask neighbors or relatives to periodically visit the apartment or house and turn on the water so that it does not have time to evaporate from the siphon. Another way is to pour a small amount of vegetable oil into this part: it forms a film on the surface of the water that slows down the evaporation process.
• A bad smell will not appear if you cover the drain with a mesh: it will trap food debris and reduce the risk of blockages. You should also clean dishes before washing and wash them with hot water and detergent.
• Periodically assess the condition of your plumbing fixtures and promptly replace failed parts. If you have to complex repairs, it is better to seek help from a specialist.
• You can remove plaque that forms on pipes during operation and prevent the appearance of blockages and unpleasant odors through regular preventive cleaning. It is advisable to carry them out once a month, using household chemicals or home remedies.

Now you can eliminate the smell from the sink in the kitchen or bathroom and protect yourself from such a nuisance.

Why does the kitchen smell like sewer?

Before you begin the active phase of getting rid of the fetid sewer odor, you need to find out the reasons for its appearance.

Why is sewer smell dangerous?

Air from the sewer, entering an apartment or house, in addition to the disgusting smell, has a negative impact on the health of the people who inhale it. It is not for nothing that a person feels an aversion to certain aromas; this happens in cases where the substances emitting these odors can cause harm.

In this case, these are substances such as hydrogen sulfide, ammonia and methane. The strongest-smelling ones are ammonia and hydrogen sulfide; methane has no odor at all, but this does not make it any less harmful. If you breathe these gases constantly, the consequences will not be long in coming. The respiratory and nervous system. Feelings of anxiety may arise for no reason, breakdown or in rare cases, fainting.

What to do to identify a malfunction

The easiest way is to ask a plumber for help. But you will have to wait for some time and its services are not free. In case of complex breakdowns, you cannot do without a professional, but in many situations you can handle it on your own.

First of all, observe the functioning of the sink. If the water drains as expected and the odor does not decrease in intensity, try flushing the drain system with hot water and plumbing cleaners. If there is no positive result, we disassemble and clean the siphon, inspect the pipes and, if necessary, clean them too.

A visual inspection of the water drainage units from the sink will help identify cracks in the corrugated pipe or other causes of leaky connections of sewerage elements. You need to make sure the pipes are dry and free of cracks and gaps. If such faults are detected, they can be eliminated with sealant, foam, or the installation of special adapters or rubber seals. Parts that cannot be repaired will have to be replaced.

How to eliminate bad odor

Having discovered a malfunction, you must immediately begin to eliminate it; this can be done using the methods described below.

How to get rid of odor from a sink drain - video:

We use a cable to clean sewer pipes

If you take an ordinary metal cable and try to clean a pipe with it, you will most likely not have a positive result. For these tasks there are special cables that are equipped with some specific modifications. Their length is 3-5 meters (there are more). The cable can be equipped with a special brush at the end or a spiral hook. There must be a handle with which rotational movements are performed.

To remove a sewer clog with a cable you need:

• Clear access to the riser and remove the corrugated siphon pipe from it.
• Insert the cable into the pipe and push it as deep as possible.
• With one hand we begin to rotate the movable handle of the device, while the other hand holds the outer casing. During the cleaning process, the cable seems to be screwed into the pipe.
• Having performed these manipulations until the cable hits the blockage, we try to either push it further along the pipe, or pull it out with a hook at the end of the cable.
• There is a third option - try to break through the blockage with a cable, and then destroy it as much as possible by consistently moving the cable in opposite directions.

After the procedure, the instrument must be thoroughly washed, lubricated with machine oil to prevent corrosion, and stored.

plunger

This plumbing fixture should be used if you are sure that the siphon is clogged and there is no desire to disassemble it. You can remove a clog from the sink using a small plunger. If the assortment is limited to one copy, we use the one that is available.

1. Install the rubber cap over the drain hole in the sink.
2. Turn on the hot water and add enough water to cover the plunger cap.
3. We close the water and make movements with the plunger, alternating directions up and down, pumping water inside the cap.
4. After several forward movements, the plunger must be pulled out, as a result of which part of the contents of the siphon will end up in the sink.
5. Turn on the hot water and wash away any remaining dirt.

If suddenly you don’t have a plunger at hand, and you urgently need to get rid of the blockage in the sink, you can use improvised means, for example, a paper milk or juice bag. We cut off the top lid of the bag, cover the cut hole in the sink and follow the instructions for cleaning with a plunger, starting from step 3.

We disassemble the siphon

Before disassembling it, you need to make sure that this is the reason. To do this, just pull the corrugation out of the riser, lower it into a bucket and pour water into the sink. If water does not flow from the corrugation, we disassemble and inspect the siphon.

1. We place a bucket under the siphon so as not to spill any water that may be in it.
2. We unscrew the lower part, the so-called reservoir. We inspect, clean, if you don’t help, we disassemble further.
3. Unscrew all the plastic nuts and carefully remove the pipes. Then you need to remove the blockage and put the siphon back together.

After complete disassembly and cleaning everything should work as expected if assembled correctly (see instructions for the siphon).

We use cleaning products

You can remove dirt in the sink using both kitchen products and special means. Let's look at the most effective ways:

In addition to the “mole,” there are also a lot of special tools, the use of which is regulated by the instructions attached to them. You can buy them in supermarkets or household chemical stores.

Preventive actions

In order to eliminate sewer smell from the sink in the kitchen or bathroom as little as possible, you need to follow some rules:

What causes sink odor?

An unpleasant smell from the sink is a serious problem that not only violates sanitary and hygienic standards, but also annoys any housewife. There are many reasons.

Through which sewer “odors” can escape and fill the room with a stench. Most often, an unpleasant odor in the bathroom is caused by:

Important! If the cause of the unpleasant odor lies in the high humidity of the room, then a forced ventilation system will help remove it. Fresh air will dry out the room and also draw out sewer odors.

Sewage problems

The bathroom has many plumbing fixtures: bathtub, washbasin or sink, toilet, washing machine. All these devices are connected not only to the water supply, but also to the sewerage system.

If during installation the sewerage system is connected to plumbing equipment with technical errors and flaws, an unpleasant odor may arise from the bathroom sink. The most commonly diagnosed problems with the sewer system are:

• During installation, the sewer pipe elbow could have been installed with the wrong slope or at the wrong height. Because of this, wastewater stagnates inside the drain of plumbing fixtures, and the room smells like sewage.
• If the device was connected using a corrugation, it may become deformed from high temperature, lose their shape or become “overgrown” with dirt and grease from the inside, which makes it difficult for wastewater to flow out.
• If the sewer is clogged, then the waste water does not go away, but sits inside the device. Because of this, a characteristic toilet odor appears, which can be removed by cleaning the sewer with chemicals or mechanically.
• The water in the siphon seal of a plumbing fixture may evaporate due to the fact that the sink has not been used for a long time. This is why, after a long absence from the apartment, the sink smells unpleasant.

Note! Any defect in the installation of a sewer system in a bathroom, be it an incorrectly selected pipe cross-sectional diameter, poor sealing of joints, or an incorrectly set slope, is fraught with an unpleasant odor. Therefore, it is important that the pipes are laid by an experienced craftsman who will take into account all these nuances.

How does a water seal work?

Every plumbing fixture that is used in the bathroom and connected to the sewer system has a siphon. A siphon is a special device that does not allow foreign odors to penetrate from the sewer pipe into the room. It is made of brass, plastic or other material.

There are models of siphons with a water seal, a membrane seal and a dry seal. Thanks to its special curved shape with one elbow, this device creates a water plug inside that prevents air from the sewer pipe from entering the sink or bathtub. Siphons perform the following functions:

1. Removes unpleasant odors that may enter the room from the sewer pipe. While the plumbing fixture is being used and the water in the water seal does not dry out, air from there cannot penetrate up the pipe.
2. Protects against sewer blockages. They filter out large debris that ends up in your sink or bathtub drain. All large impurities fall into the siphon sump, after which it can be removed from there.
3. Sewage is directed by gravity into the sewer system. The shape of the siphon is such that wastewater easily flows through the drain into the sewer system without stagnating at the bottom of the sink or bathtub.

Please note that the water seal only works until the water in it dries out. Therefore, when no one uses a plumbing fixture for a long time or there is no water supply for a long time, the liquid in the siphon dries out, which is why there may be a sewer smell in the bathroom.

If the reason that the bathroom smells is because the water seal has dried out, then the easiest way to deal with this problem is to simply fill the siphon with water and thoroughly ventilate the room.

How to deal with the problem?

Many housewives are wondering how to eliminate the smell from the sink in the bathroom, how to get rid of the persistent aroma of the sewer, if a sponge and detergent no longer help.

If the bathroom is cleaned regularly and thoroughly, but the odor is still present, then the problem is most likely in the sewer system, so we will deal with it. To get rid of sink odor, follow these instructions:

Remember! We clean the bathroom quite often, because keeping it clean is not easy. However, we often forget that the pipes and siphon need to be cleaned periodically so that no unpleasant odors bother you. In addition, it is necessary to carry out preventive measures: you should not throw cleaning materials, garbage, grease into the sink, you need to clean the siphon sump and change the corrugation on time.

Water drainage system and unpleasant smell from the sink

The design of any drain includes a siphon, the S-shaped elbow of which forms a so-called “water lock”. The siphon constantly contains a certain amount of water, which traps odors from the sewer and prevents them from entering the room. The cause of odors in the bathroom can be any violation of this design:

• incorrect installation of the flask siphon. The plastic pipe should be immersed a few centimeters in water. If it doesn't reach the water seal, the smell will seep out. The problem can be eliminated by adjusting the lifting height of the pipe;

• corrugation deformation. When using a corrugated pipe as a siphon, be sure to secure it special devices, included in the kit. Otherwise, it will sag and stretch;

If the installation of the siphon was not carried out by a specialist, the water seal may be formed incorrectly, as a result of which water will immediately go down the drain or pour back into the sink.

• long downtime. If the drain has not been used for a long period, the water in the siphon may evaporate. To eliminate the resulting unpleasant odor, pass a large amount of water through the siphon. To prevent this situation before a long trip, pour a little vegetable oil into the drain hole.

Other causes of odor and ways to eliminate them

Even with a good siphon, you can detect an unpleasant odor in the bathroom. The method for eliminating it depends on the cause of its appearance:

1. Damage in a sewer pipe. An unpleasant odor may come out not from the drain hole, but through chips and cracks in the pipe. In this case, the damage should be repaired or it should be completely replaced.
2. Depressurization of the seam between the drain and sewer pipe . Remove the old caulk and fill the joint with new mixture.
3. Airing or clogging of the riser. To solve this problem, you will have to seek help from housing office specialists.
4. Accumulation of dirt and grease at the bottom of the siphon. The siphon can be cleaned using chemicals or mechanically.

Cleaning the siphon from dirt

If the cause of the stench is a clogged siphon, try cleaning it using chemicals or improvised means. In the departments of household chemicals you can purchase one of the special products (Mole, San Klin, Domestos, etc.). All of them are made on the basis of caustic soda (caustic sodium). And the difference between drugs from different manufacturers lies in the concentration of caustic and the difference in auxiliary additives. They can be produced in powder, liquid or gel form.

When cleaning pipes with chemicals, personal safety precautions should be observed. Wear rubber gloves and protect your eyes from splashes. After completing the procedure, ventilate the room.

Fresh blockages can be dealt with using available tools:

1. Pour food into the drain hole table salt, and after 1-1.5 hours, rinse it with water.
2. Pour soda ash into the drain, add vinegar and plug the hole. After 30 minutes, drain the water.
3. Dilute 2 tablespoons of washing soda in a liter of boiling water and quickly pour the solution into the hole.

If the above methods do not help, you should mechanical cleaning siphon using one of the special tools:

• plunger– a tool for pumping out air and contaminants from water pipes. Can be mechanical or electromechanical;
• cable– pushes mechanical impurities towards a larger diameter outlet pipe.

Knowing the causes of unpleasant odors from a sink or bathtub drain and how to eliminate them will allow you to quickly and competently deal with this problem on your own.
