How to drain water from an Ariston heater. How to quickly and correctly drain water from a water heater? Quick, adjustable drain via cold water inlet

Sometimes a situation arises when it is necessary to drain the water from the boiler. It would seem that the task could not be simpler. However, for an ignorant person this can become a problem, because the design of the water heating apparatus is such that water will not simply flow out of it. Clarify the issue of emptying electric boilers This article is intended.

Do I need to drain the water from my water heater?

First, about the reasons that may cause such a need. In fact, it is not recommended to empty the tank unnecessarily, much less keep it empty. After all, instead of water, a vacuum will not arise inside the container; air will take its place, and it will negatively affect the condition of the tank and heating element.

Although there are exceptions - capacity from of stainless steel and heating element with ceramic coating are not afraid of such influences. But most inexpensive boilers do not have any protection and it is better to keep them filled.

For reference. If the device is not intended to be used long time, then the water in it can be renewed once every 2 weeks by opening the hot tap on the mixer for a few minutes. This way the water will not stagnate and harmful microorganisms will not appear in it.

There are 2 serious reasons that make it necessary to drain the water from the water heater:

• maintenance or repairs are required. This includes descaling the container and replacing the protective magnesium anode. It is recommended to perform the operation once every 2 years.
• the room where it is located storage boiler, not heated in winter time. To avoid rupture of the tank as a result of defrosting, you must keep the device turned on or empty it. There is no point in incurring unreasonable costs for electricity; it is better to drain the water from the boiler.

How to empty the storage boiler?

First of all, to simplify the emptying process, the water heater must be correctly connected to the water supply networks. The connection diagram looks like this:

When everything is done in accordance with the diagram, the water is drained from the water heater in the following sequence:

• the tap on the water supply to the house is turned off;
• the boiler must be disconnected from the power supply and the plug must be removed from the socket;
• close the valve that cuts off the unit from the supply pipeline cold water;
• open the hot tap on the nearest faucet and wait until the water drains;
• leave the mixer open so that air can flow into the tank instead of water;
• connect a hose to the drain tap and direct it to the sewer;
• open the drain valve and drain the water from the boiler.

Advice. Before starting the procedure, it is recommended to wait until the water in the container has cooled to a temperature of 40-45 ºС, so as not to get burned. The wait will take quite a long time - about 6 hours. When this is not possible, you must take all safety measures and perform the operation very carefully.

This is the most convenient way, due to the correct piping of the boiler. When emptying is completed, all taps should be closed and maintenance or repair work can then begin. Once completed, the water heater must be filled again; do not forget to do this before plugging in the electrical appliance. To fill, you need to supply water to the house, and then alternately open the shut-off valves of the boiler and the hot water on the mixer. The signal that the container is full will be a stream of water from the mixer.

Emptying a boiler that is not connected correctly

You will have to tinker a little when the water boiler is connected to the networks incorrectly. This happens if some unfortunate master took on the installation and did not bother to install not only a tee for draining, but also cut-off Ball Valves. Unfortunately, such situations occur quite often; an example of how not to connect the boiler is shown in the diagram:

First, similar operations are carried out to cut off the water supply entering the apartment or a private house. Water flows as much as possible through the hot tap of the mixer. Then the problem is solved in two ways - slow and fast, it’s your choice which one to choose.

If you have enough time at your disposal and it is in good condition, then there is an option to get by with little blood. After placing a tube on the valve's discharge pipe and directing it into the sewer, or simply placing a bucket, press the valve lever. It must be said that forced discharge through the valve will take a lot of time. A boiler with a capacity of 80 l will empty for at least 2 hours.

There is a way to empty the water boiler much faster, but to implement it you will still have to wait for the device to cool down, since it will not be possible to avoid getting your hands wet. Having completed all the manipulations of shutting off and draining the water through the mixer, as well as disconnecting the device from the network, you need to unscrew the pipe from the outlet fitting of the water heater with an adjustable wrench or gas wrench. Don’t forget to place a bucket in advance; some water will flow out through the fitting.

The next step is to unscrew the pipe from the safety valve. Because he doesn't let the flow in reverse side, then nothing will happen as a result. Water will flow out after you unscrew it completely. safety valve. To control the process, you must first loosen it with a key and substitute a bucket. Then, plugging the outlet pipe with the finger of one hand, unscrew the valve completely with the other hand. By releasing your finger, you can drain the water from the boiler into the bucket, and when filling, close it again, creating a vacuum. Clearly this method shown in video:

Advice. Taking advantage of the fact that the boiler piping is still disassembled, buy the missing fittings and assemble it correctly, as shown in the first diagram.

The complete disassembly method is also suitable for emptying a small water tank with a water heater whose pipes are directed upward. Here you can’t do without removing the tank from its brackets, then turning it over and draining the water.

Conclusion

As you can see, the procedure is not difficult if you have the correct piping of the water heater. Otherwise, it will take some effort and time to empty the unit. It follows from this that installation and piping must be carried out in accordance with generally accepted rules according to long-proven schemes.

Modern market household appliances is distinguished by great diversity. Manufacturers regularly offer their consumers new, more improved models. These include water heaters. Correct operation and compliance with all requirements specified in the instructions will help extend the life of the equipment.

Design Features

Water heaters, or boilers, have taken a strong position in almost every apartment or private house. They provide housing with a regular supply hot water, helping not to depend on central utility systems. A seemingly simple device actually has complex design and performs quite responsible functions. It automatically maintains the temperature of the water in it.

The modern market of similar household appliances presented in a wide range. Each owner will be able to find a device suitable in design, size and pricing policy. Despite the external differences, all water heaters are designed according to the same principle.

Hidden inside the case is a heating element - a tubular electric heater that is directly responsible for heating. It and other parts (safety valve, magnesium anode) are protected by a thermal insulation layer that runs between the outer and inner walls of the housing.

At the bottom of the structure there is a thermostat, which is responsible for the ability to regulate the temperature. On the outer walls there are special fastenings for possible equipment water heater on a wall or other surface.

Several simple and familiar components are responsible for performing important functions and making the water heater easy to use.

Possible reasons for water drainage

From time to time it may be necessary to drain the water to empty the boiler tank. Many people are interested in whether it is necessary to drain the water from the water heater for the winter. Let's consider cases when you need to drain the water.

Possible situations:

• The equipment is located in a place that is not heated for a long time, for example, a summer house. Stagnant water in the storage tank and pipes freezes. This may damage the internal structure or rupture the tank;
• Routine cleaning of the inside of the tank. Hard water promotes the appearance of rusty deposits and bacteria. Periodic cleaning is necessary in such situations;
• Replacing the old magnesium anode with a new one. The anode is engaged in purifying the incoming water from harmful impurities, accumulating them in itself. It is recommended to replace a new device annually;
• The appearance of leaks and leaks when using the boiler. If the walls are damaged, operation of the device must be stopped;
• Appearance unpleasant odor indicates the need for urgent cleaning. It may appear due to stagnant water in the tank.

It is not recommended to carry out liquid drainage procedures unless absolutely necessary. Ideal option there will be devastation storage tank 1 time per year.

Available options

Experts identify several methods suitable for draining water from a water heater. A competent approach and compliance with safety precautions will help carry out the draining process quickly and without injury or burns.

Reference. Before carrying out the procedure for draining the liquid, you must read the instructions for a more detailed understanding of the design of the water heater.

Several ways to drain water from a water heater:

Following all the steps during operation will help empty the water heater tank.

What to pay attention to

Any of the above processes does not guarantee complete drainage of water. To thoroughly empty the boiler, it is necessary to disassemble it. To do this, carefully unscrew the cover on the bottom surface and carry out the process of disconnecting the wires.

When disconnecting the wiring, you will need to remember all the details of the initial connection to continue operation. The flange serves as a support for the tubular electric heater; it must be unscrewed counterclockwise. Slightly loosening the nut will allow the liquid remaining at the bottom to drain.

After complete emptying, you can completely unscrew the flange. When removing the heating element, difficulties may arise due to scale and rusty deposits on its surface. To do this, you can gently rock the water heater, gradually pulling the heating element up.

Safety precautions

In the process repair work safety regulations must be followed. This will help avoid potentially dangerous injuries and burns, and also extend the life of the water heater.

First of all, experts do not recommend draining the water yourself, provided that the device is still under warranty. Even minor damage will void the warranty. In this case, it is better to turn to professionals for the service.

Before carrying out repair work, the device must be disconnected from the power supply network, and the liquid in the container must be allowed to cool to room temperature. This will prevent the possibility of burns.

It is not recommended to drain water unless absolutely necessary. When empty, the internal casing of the boiler is more susceptible to corrosion. The ideal option would be to clean the internal walls and replace the necessary parts once a year.

Conclusion

Electric water heaters have become a constant companion in any apartment. Timely care, compliance simple recommendations and safety precautions will help you carry out repair processes yourself and extend the life of the device.

When it becomes necessary to drain water from a water heater, many people at first glance find this problem funny. But when it comes to practice, home craftsmen have a lot of questions. Common mistakes and unforeseen difficulties can be avoided if you have at hand detailed description the entire draining process.

Storage tank design

A water heating device is present in almost every living space. Its full and uninterrupted functioning is ensured by correct use and timely service. Many manufacturers in the operating instructions for the device strongly do not recommend draining water from it unnecessarily and leaving it empty for a long time. The air present inside the equipment negatively affects the inner surface of the tank and worsens the condition of the heating element.

There are expensive water heaters made of stainless steel. They are usually equipped with dry heating elements that have a durable ceramic coating that is resistant to prolonged contact with air. As for budget options boilers, they are deprived of such protection, remaining without water for a long time. Subsequently, such devices need to be repaired or completely replaced.

How to EASILY drain water from a boiler (water heater)!



The need to drain the liquid

Complete emptying of the heating unit capacity is carried out if the room is in winter season is not heated (for example, a country house for temporary residence or rarely visited residential property with an average temperature below +5 ° C). This mode can lead to freezing of water in the pipes, which is common cause damage to the internal filling of the tank and piping. Draining the water from the boiler and completely shutting down the system would be the best option.

When temperature regime remains within normal limits, but the device is not used for a long time, the water in it should be changed periodically. It will be enough to open the hot tap on the mixer for 5 minutes and the contents will update on their own.

Complete emptying of the tank is mandatory during routine cleaning of equipment. This event is performed 2 times during the year when using a centralized water supply without pre-treatment, and also once a year if the water is first passed through high level processing.

How to drain water from a boiler

During operation, the inside of the boiler becomes covered with scale and dirt. This layer settles on the walls, bottom and heating element, creating a certain heat insulator. The situation is aggravated by the fact that the heating element will overheat during operation, while the water will not reach the required temperature and will be supplied barely warm. With increased electricity consumption, the boiler shows minimal efficiency. The way out of the situation is to drain the tank and dismantle the heating part, followed by descaling. As a result, the equipment will begin to work in full mode and will last for a long time.

You can't do without emptying the boiler, if any of its functional parts have expired the warranty period. Repair or replacement of the problematic element is carried out only with drained water, which, upon completion of all measures taken, is pumped back into the connected system.

The reason for draining the water heater is the formation of an unpleasant odor emanating from the tank. The reason for this is irregular or infrequent use of the unit. At the same time, the water silts up and creates a characteristic odor; when it is completely replaced, the problem is solved independently. You cannot do without emptying the tank if you transport the boiler or carry out repairs.



No need for descent



It is not always necessary to remove the contents of the water heater. When storing the unit for summer period It is recommended to keep a small amount of water in it. This prevents the formation of “early” corrosion and prevents combustion of the unit if the owners inadvertently connect it without first filling it.

If you want to change the contents of the tank after long-term preservation of the system, it is not recommended to carry out a complete draining procedure. It will be enough to refresh the water in the tank through the tap several times, which experts recommend doing once every couple of months, passing about 100 liters of water (alternately cold and hot) through the unit.

If the boiler is under warranty service, you should not act unauthorized and carry out any manipulations with it. Service center will refuse repairs if the water heating system is leaking.

Start of the process

Before deciding how to drain the water from a storage water heater, you need to familiarize yourself with several popular methods of this process. First of all, the unit must be turned off from the power supply. This will help prevent equipment short circuits and possible injury to the technician.

Next, the supply of liquid to the working container is shut off through the valve, and the boiler itself is left in this state for some time to cool completely. The next step is to remove the cold and hot water, after which you can proceed directly to emptying the tank.

Popular methods

There are several methods to drain a water heater. Complexity does not arise in any of the cases, and each of them comes down to a single principle. The differences lie only in design features operating units.

The work process does not take much time, but maximum accuracy and caution will not be superfluous. Taking into account some nuances and advice from the experts, draining the tank yourself will be hassle-free and will not negatively affect the further functioning of the heating device.

Working with safety valve

When installing a boiler into a common communication system, it is necessary to ensure that there is a safety drain valve. Its standard location is the area on the hose or pipe for cold water in front of the entrance to the container. This valve is used for emergency drainage of water from the water heater.

Such emptying of the container is spontaneous if the internal pressure of the boiler exceeds the permissible maximum. As for the emergency tap itself, it is better when it is supplemented with a screw-type handle with an extension, to which a drain pipe is quickly connected.

The functionality of the described unit must be checked regularly. The procedure is extremely simple: the valve turns, and after a while water appears, coming out in an even stream under pressure. It happens that liquid is supplied through an open emergency valve. unevenly or not at all. In such a situation, you should check the tap for blockages that would prevent it from performing its safety function. A detected clogged valve must be immediately repaired or replaced if nothing can be done about it.




Draining water through a working emergency valve is a trifle. The part is rotated and the liquid is discharged out through the attached outlet hose. With a completely empty tank, you can carry out the planned activities:

• scheduled cleaning;
• odor elimination;
• replacement of parts;
• canning for the winter.

How to properly drain water from a (water heater) BOILER.

Devastation through water drainage

Compared to the previously described procedure, this method is more difficult. In addition to responsibility and maximum accuracy home handyman You will need some plumbing skills. The work process requires the presence of an adjustable wrench, which will have to unscrew the nuts that reliably preserve the integrity of the entire structure. Created by professionals step-by-step instruction, defining how to drain water from a water heater at home:






In some communication systems, diverter valves are mounted directly on the faucet to warm water. In this case, the drain level must be controlled by the emergency element, without affecting the hot valve. Subject to simple rules The water heating tank will empty in a few minutes; the duration of this procedure depends on its total volume.

Output via hose holes

In some cases, descent is possible working fluid directly through tubes designed to discharge and supply hot and cold water. But so simple method can only be used when a device with a heating heating element is installed above the bathtub, since there is no control over the speed and force of the drain.

The process involves unscrewing and then removing the cold hose from the inlet pipe and the emergency valve. Next, you need to remove the hot tube in a similar way. The liquid present in the container will spontaneously begin to drain into the bath, and the boiler will be completely ready for the necessary manipulations:

• repair;
• cleaning;
• replacement of parts.

Removing residual moisture

Regardless of how you manage to drain the boiler, the working fluid will not be completely removed from its tank. This can be explained design features water heater of any manufacture.

It will only be possible to remove every drop of water if it is practically complete disassembly equipment, thorough cleaning of the internal space and elimination of existing breakdowns. After this, the dried structure is assembled for subsequent use or stored disassembled until the new season.

Disassembly is preceded by draining the working fluid in a suitable way. Next, remove the decorative cover at the bottom of the container, carefully disconnect the wires leading from the signal lamp to the surface, and electrical cords, the location of which is recommended to be remembered. The next step is to unscrew the flange counterclockwise, which is the support for the heating element. When the boiler nuts are then loosened, the remaining moisture will flow out spontaneously. Only after this can you finally unscrew the fasteners and remove the heating element from the recess.

The procedure for emptying a water heater is simple, but requires precise and consistent steps. If you have the slightest doubt about your abilities, it is better to trust similar work professionals.

Sometimes it becomes necessary to drain the water from the water heater. Do you think it's easy? Yes, it’s not difficult, but you need to know the nuances, without which you will not be able to release the boiler.

How to drain water from a storage water heater?

Most often, the boiler tank is hung on the wall or mounted on supports. Two pipes or two flexible hoses are connected to the water heater from below - cold and hot. Cold water enters the water heater through the cold inlet pipe (hose). Hot water comes out through the hot hose.

Hot water is released while the tank is simultaneously filled with new cold water. When the cold water is turned off (in the event of a water supply accident or repair of the riser in the entrance), cold water does not flow into the tank. Therefore, hot water cannot flow out of the boiler even when the tap is open. Now, based on the described operating features of the water heater, we will tell you how to properly drain the water from the boiler.

To do this, it is necessary to open the cold hole (cold water outlet) and at the same time ensure air access into the tank through the hot water outlet. How to do this depends on the design of the boiler and how it is connected (read here). We will look at several ways to implement our plans.

Method number 1: drain the water using a safety valve

Proper installation of the water heater requires the presence of a drain safety valve. It is installed at the entrance to the tank (on cold pipe or hose) and is intended for emergency drainage of water from the boiler. This emergency drain occurs spontaneously if, for some reason, the pressure inside the tank exceeds the specified safe values.

The emergency valve has a spout for connecting the drain tube, and there is a screw (it looks like a handle that is used to open and close the valve). Why does the valve need to be opened? To check its functionality. This is done once a month. Open the valve handle and see if water flows from the spout. If it leaks, the valve is in working order. If it does not flow, the valve is clogged and does not perform a safety function. It needs to be cleaned or replaced.

Now the main thing is how to drain water from the boiler using a valve? This is the easiest way to empty the heating tank of water. You just need to open the valve of the emergency device. If the valve is working properly, water will flow from the spout (or the hoses that are attached to the spout).

The flow rate of water through the safety valve is low. This means that a tank with a capacity of 80 liters will be emptied in about 2 hours. If the valve is clogged, the flow rate of water will be even less. In this case, the boiler release time may be 3 or 4 hours. To quickly drain the water from the tank, you must use the method described below.

Video about draining water using an emergency valve

In the plot you can clearly see the process of draining water.

For those who are not professionals: if water does not flow from the valve spout, this means that the device is faulty (more often, it is clogged), and it will not be possible to drain the water this way.

Method number 2: drain the water from the tank through the cold water hole

This method is more complex and will require the willingness to pick up an adjustable wrench to unscrew some of the nuts in the boiler connection system. How to drain water from the boiler in this case?

1. Before starting work, we shut off the entrance of cold and hot water to the house or apartment and turn off the boiler from the power supply. If you are not a professional in this field of activity, you should strictly use this rule.
2. Check to see if the hot tap is closed. If it is open, then water from the boiler will flow very strongly after unscrewing all the nuts. And we need to control the process and not flood the room with several buckets of water.
3. We place a bucket, basin or other container under the boiler to collect water.
4. We unscrew the nut that connects the safety (emergency, bleed, check valve) to metal-plastic pipe or with flexible connecting hose ( flexible hoses used when connecting a plastic water supply).
5. Disconnect the hose or pipe from the safety device.
6. We unscrew the nut that connects the safety (reset) valve to the heating tank pipe. For this we also use an adjustable wrench.
7. We remove the relief valve (you can assess its condition, the presence of blockages, and, if necessary, rinse with water). If the hot water tap is closed (we checked this before starting work), then water will not flow from the tank at all or will leak in small portions. In order for water to flow out more strongly, it is necessary that air enters the tank. How to do it?
8. Open the hot water tap. At the same time, through hot pipe Air will begin to flow inside the sealed heater tank. Water will flow faster from a cold pipe.
9. If it is necessary to regulate the flow of flowing water, we use a hot tap. To reduce the flow, turn off the hot tap.
10. If the boiler connection system has a tap at the outlet of the water heater (on the hot pipe), then instead of the usual hot tap, you can regulate the flow of water with this tap.

The described method allows you to drain the water from the tank in a few minutes (from 3 to 5).

Video about draining water using the cold water hole

To make it more clear what and how to do, watch the attached video. This way you can get the job done faster.

Method number 3: unscrew the incoming and outgoing hoses

To drain the water from the water heater very quickly, you can use this method. But this method of draining water from the boiler is the most uncontrolled. It can only be used if the water heater is installed directly above the bathtub. It will be impossible to regulate the flow of water during draining, stop it or weaken it if necessary.

To drain, twist the cold hose and safety valve from the inlet pipe, and then remove the hose from the hot pipe. Water from the tank rushes down through both holes and empties the tank in a couple of minutes.

Any of the above methods does not completely empty the boiler of water. In order to completely drain everything to the last drop, it is necessary to disassemble the storage tank.

Do I need to drain the water from the water heater?

This depends on its operating conditions, design and frequency of use of the boiler. When does it become necessary to drain the water?

• if the water heater is located in a country house or in another periodic residence. With the onset of frost, the water inside can turn into ice and “break” the sealed storage tank;
• draining water is useful when there is a water supply accident and there is no water in the apartment. The storage tank can provide 80-100 liters of water. It can be used to wash hands, vegetables or flush the toilet.

Should I drain the water from the water heater or is it not necessary during departure? For a boiler installed in a heated room, draining the water when the owners leave is not necessary. However, you need to take into account the design features of your heating device:

• If the tank is made of stainless steel, it is not afraid of corrosion in water. But to corrode in humid air it will be faster;
• For copper heaters, it is better to drain the water. Copper is more degraded in hard water than in humid air. And the service life of heaters is always shorter than that of a storage tank (they have to be changed more often);
• If the water in the water heater comes from a centralized water supply, it contains disinfecting components (bleach). They limit the growth of any bacteria and the appearance of an unpleasant, stagnant odor;
• If the water in the tank comes from a well, it does not contain chlorine. Therefore, it may stagnate with the formation of a putrid, unpleasant odor. Draining such water prevents its stagnation and decay.

To get rid of the smell of stagnant water, you should rinse the boiler (turn on the tap and drain the water from the tank for a long time until all the stagnant liquid comes out). Then fill the heater and turn on maximum heat (90-95? C). This “boiling” can be done several times if necessary.

If you decide to drain the water, drain only after the hot water has completely cooled to room temperature. The remaining manipulations are already familiar based on the article.

The need to empty the boiler often arises among users, so the question of how to drain water from a water heater is quite relevant.

Many manufacturers assure buyers that this operation is quite simple, but in reality people often encounter certain difficulties.

Often, the operating instructions do not describe all methods of manipulation, so it is simply necessary to consider the most acceptable methods.

How to drain liquid from a boiler correctly?

Before you start draining liquid from a water heater, you need to superficially examine its design.

All boilers have 2 tubes that are connected to heating device. The first one is needed to collect water, and the second one is needed to drain it.

No less important element is a shut-off valve, it is a kind of protection valve. If you twist it, the water will leave the boiler, but not in full, so no more than 2-5 liters are removed.

You can drain water from a water heater of any brand only after disconnecting it from electrical network.

If you look at it, the devices various brands differ in structure, and the method of draining water varies depending on their characteristics.

The principle of draining water from a Termex boiler differs from the method of emptying an Ariston tank.

To drain the collected liquid from the Thermex tank, you must perform the following steps: sequences:

1. Close fence valve running water.
2. The liquid from the tank will be consumed. For best effect you should open a faucet that supplies hot water in the room in which the water heater is located. This is necessary to reduce pressure.
3. After the hot water has drained, it is required close tap.
4. Using an adjustable wrench, you should unscrew nut at the cold water entry point.
5. Need to get on the phone right away let down a hose through which the remaining water will drain into the sewer.

You must drain the water from the Ariston storage water heater as follows:

1. After disconnecting the device from the electrical supply, you must open top faucet plug.
2. Remove the shower hose block hungry water and block water supply taps.
3. Valves on the tube for drainage and inflow of water are needed twist together with nuts from polymer materials.
4. From the mixer you need put away cap and twist screw.
5. Housing needed unscrew from the inside of the tank, and then open the plug.
6. Open a valve closed with a plug for free drainage of liquid.

You can start draining water from the tank that heats the water only after turning off its power. This is exactly what it's about important point Many owners forget.

After disconnecting the device from the network, you should wait several hours before starting to drain the water. The fluid in the tank may be too hot and may cause skin burns.

After turning off the power to the water heater, you need to close the cold water intake valve. Otherwise, efforts to drain the water may be in vain.

In what cases should water be drained?

Draining the water from the water heater must be carried out in the following situations:

1. If the boiler remains for a long time in a cold room, the temperature in which drops to 5 degrees. It is for this reason that summer residents often empty their water heaters. This necessary measure, because leaving the device in a cold place for the winter unheated room dangerous. This may cause it to fail or adversely affect its performance.
2. At necessity carrying out repair work to replace the heating element. Draining the water in this case is a necessary measure, because it will not be possible to begin the replacement without draining the liquid.
3. For removal scale from the internal surfaces of the boiler. Many masters claim that this manipulation needs to be done at least once every 3 years. This is due to the fact that scale accumulated on the internal surfaces affects the heating rate of the liquid. This leads to wasted energy.

Draining water is not the best simple procedure, but it is necessary to perform it in these cases.

If there is water inside the boiler when low temperatures, it will turn into ice, which may cause damage internal parts devices.

It is important to properly drain the water from the boiler, because even a small residue of a few liters of water at cold temperatures can damage the device.

We should not forget that you can begin disassembling the device and carrying out repair work only if the warranty period has expired. Self-disassembly of a device that is under warranty will void the opportunity for free repair.

How to drain water from a boiler with a tee?

If the water heater is equipped with a tee, draining the water from it is quite simple. The drain valve is always located on the lower zone of the boiler between the valve and the pipe that provides running water.

To drain the liquid, you must close the valve on the cold water intake pipe. After this, you need to open the drain valve.

When draining water using this method, you need to remember that a small amount of liquid may remain inside the unit. You can remove water using the method of draining the residues.

How to drain water from a water heater using a trigger lever?

The method is suitable for removing liquid from boilers equipped with a special lever. Like structural element In the plumbing industry they call it a trigger. The descent method in this case looks extremely simple.

Similar element located vertically and parallel to the cold water intake pipe. Manufacturers often place this element on the safety valve.

In order to drain water from the water heating tank, simply bend this lever at a right angle.

Attention!

You can carefully connect a hose to the valve hole, through which the liquid will immediately go into the sewer.

The draining process is quite long. Depending on the initial volume of the boiler, the time varies from 1 to 3 hours.

How to drain water from a boiler by removing the check valve?

This option can only be used in extreme cases, because flooding of a living space will be very difficult to avoid.

Check valve placed on the lower cold water supply pipe. This element is responsible for the emergency pressure reduction function.

Attention!

Immediately after removing the valve, water will begin to come out under enormous pressure! It is extremely important to allow the water to cool before starting the operation, otherwise the master himself will be scalded with liters of hot water and the entire room in which the boiler is installed will be flooded.

To drain the boiler using this method, you need to unscrew the warm water supply from the tank and remove the safety valve, wait until the water is drained. The technique is extremely simple, but it can only be used in extreme cases.

How to drain water from the tank if it fails?

If the device fails during operation, it is better to entrust the drainage of water to a service organization, especially if the device was purchased recently and is under warranty service.

In this situation, the first thing you need to do is contact the center warranty service. You must take with you the documents for the device, the warranty card and a receipt confirming the fact of purchase.

Often, minor repair work is carried out by craftsmen in the buyer’s apartment without removing the device. If major repairs are necessary, specialists will drain the liquid from the device themselves.

If the service warranty period has expired, you can try to drain the water from the boiler yourself and repair the water heating tank.

This can only be done after accurately identifying the problem and studying information on how to solve it. Incompetent intervention in the operation of the device may affect its further operation, so it is better to seek help from specialists.

Draining remaining water from the water heater

It is quite difficult to drain the water. But even if the manipulation is performed correctly, water may remain in the water heating tanks.

This is directly related to the design features of the devices. It is necessary to remove water to the last drop in the following situations:

1. The water heater remains in winter period in a cold room.
2. Transporting the device over long distances.
3. Carrying out repair work.
4. Cleaning from scale accumulation.

To dismantle and replace the heating element, it is necessary to remove all liquid from the device.

To perform the operation, you must follow the following recommendations:

1. Disconnect all electrical components of the water heater.
2. Remove the casing from the boiler.
3. Prepare in advance a large tray in which you can place the heating device.
4. Be sure to install the device in the tray in a vertical position.
5. Open the nut that secures the heating element.
6. Remove any remaining liquid and scale from inside the appliance.

It is imperative to carry out drainage and removal of the device with a partner. This is due to the fact that even the most modern and small water heaters are quite heavy.

Attempting to dismantle it yourself may result in injury.

It is necessary to drain the water only in the described cases. Some owners think that draining the water is also necessary if the device is not used for a long time, but this is not entirely true.

If the water heater is located in a room where the air temperature does not drop below 5 degrees, there is no need to drain it, even if no one uses the boiler.

To maintain the operation of the device in this case, it is enough to turn on the water supply to the device several times a year and drain the water in order to avoid water stagnation.
