Homemade device for increasing water pressure. Pump to increase water pressure in an apartment or private house

A pump to increase water pressure in the water supply system is purchased to stabilize the pressure in the system. Indeed, for the simultaneous operation of several points of consumption, for example, two taps, the pressure in the system must reach 1.5 atmospheres. A washing machine or dishwasher will only operate at a pressure of 2 atmospheres (and no less). And Jacuzzis and showers with a hydromassage function “start” at a pressure of at least 4 atmospheres.

At the same time, in household water supply there is often no minimum pressure (1.5 atmospheres), not to mention standard indicators (4-4.5 atmospheres). As a result, installing a water pressure booster pump is the only way to ensure any acceptable living conditions in the house. After all, without this pump, neither a shower stall nor a washing machine will function.

And in this article we will discuss the choice of devices used to stabilize the pressure in household water supply systems at an acceptable level.

Firstly, if there is water only on the lower floors of the house. Secondly, if you open one tap, it is no longer possible to use the second source of consumption. And thirdly, if the system has a frankly weak pressure, which is not enough to service household or plumbing appliances

In short, both a conventional pump and a powerful self-priming pumping station are used if there is no stable pressure in your water supply. Moreover, problems with the plumbing will certainly affect the overall level of comfort, reducing the “quality of life” itself.

Therefore, you will have to buy a pressure pump or pumping station:

Firstly, it is quite powerful, but without excesses: after all, increasing the pressure to 6-7 atmospheres can destroy the internal elements (seals, valves, etc.) of shut-off and control valves.
Secondly, it is relatively cheap: after all, money needs to be spent “wisely”.
And, thirdly, it is compact and low-noise: after all, the immodest dimensions of the unit will spoil the entire interior of the home, and noise pollution will disrupt the comfort of living.

But both a conventional pump and a pumping station fit these criteria. What's better? Let's figure it out.

Household water pressure booster pumps

Such devices are installed in the internal water supply of a house or apartment. Therefore, pumps should not be large and noisy.

Moreover, there are two schemes for operating such equipment:

A permanent option that requires almost 24/7 operation of the device.
Automatic option, turning on the unit “on demand”.

In the first case, we only need a pump, and in the second, we will also have to add a flow sensor to it, which, of course, will affect the price of the equipment.

But the more expensive automatic option is still more profitable than the cheaper permanent one. Let us explain why: during operation, the pump heats up and fails due to overheating. Therefore, continuous use of such equipment is strictly contraindicated.

And working from time to time automatic pump, turns on only when the flow is caused by water consumption (an open tap, a washing machine on, and so on). Therefore, it will never burn out. And such a pump consumes much less electricity.

In the end, any prudent homeowner will choose the automatic option, despite the slightly inflated cost. And permanent pumps are good only in one case - if they are used in one-time operations. For example, if necessary, stabilize the pressure after activating the irrigation system. In this case, the pump is simply “plugged in” and turned off after the procedure is completed.

Pumping stations

Essentially, this is the same vibration or centrifugal water pump high pressure with a hydraulic accumulator or hydraulic tank. However, unlike pumps, stations are installed between the water source and the water supply. As a result, it is the pumping station that generates the pressure in the water supply.

Moreover, almost all systems are equipped with similar installations autonomous water supply. And to stabilize the pressure in the system, you need to either replace the existing station with a more powerful one, or replace only the pump or storage tank of the station with a more productive analogue.

In addition, to increase the pressure in the pipeline, you don’t even have to change anything! It is enough to simply adjust the operation of the pressure switch. The essence of this solution is that a special device is “responsible” for the pressure of the station - a pressure switch that monitors the operation of the pump and storage tank.

Let us explain in more detail: the pump pumps water into the storage tank, which releases it into the water supply system. In this case, the pump does not operate constantly, but only when the pressure in the storage tank is less than the minimum. Then it turns on, pumping water until the pressure in the accumulator rises to the maximum possible.

The maximum and minimum pressure in the storage tank is determined by a special relay. Increase the time of the lower pressure limit in the accumulator, and it will increase throughout the water supply.

How to choose a pump?

The selection of a high pressure pump is based on the following rules:

Firstly, the pump must work as long as needed, without pauses or long breaks, without overheating or shutting down. Therefore, you need a unit from a trusted company with a good reputation, and not a Chinese-made clone.
Secondly, the pump must increase the pressure in the system to an acceptable level of 4-5 atmospheres, and no more. Therefore, purchasing a heavy-duty station for deep wells not always justified. And if you cannot calculate the required unit performance yourself, contact a specialist. In specialized stores, this service is offered to all pump buyers absolutely free.
Thirdly, the pump must fit the purchase budget. Good equipment is not cheap. But it pays for itself due to trouble-free operation. Cheap pumps require frequent maintenance and practically do-it-yourself repair. After all, no-name manufacturers simply do not have service centers. Therefore, if you do not have plumbing and plumbing skills or do not have time for such work, buy a reliable unit from a trusted brand, for example, a wilo water pressure booster pump. This technique will pay for itself 100 percent.

As you can see: the selection rules are very simple. But if you have doubts about your decisions, contact a specialist.

Most specialized companies offer a solution to the problem of insufficient pressure in a turnkey format. That is, with calling a specialist for diagnostics, calculating and selecting equipment and subsequent installation of all units in the water supply system.

When you open the faucet in your home to simply drink water, and a sluggish trickle flows from it, the thought immediately comes to mind of installing it in the water supply line.

Adequate water pressure in the pipes is the key to the normal life of a person living in a private cottage, country house or high-rise apartment. This is very important for trouble-free operation of household appliances. hydraulic machines and parts of plumbing equipment. This is one of the very important conditions your comfortable living and the durability of your home’s expensive water equipment.

For normal operation For the main models of household hydraulic machines and plumbing units, a water pressure in the pipelines of 2 to 4 bar is sufficient. If you periodically or constantly have a lack of these indicators at the outlet of the intake taps, then you should understand the reasons for this deficiency and, if necessary, install booster pumps for yourself individually or for collective use.

Below we will describe the basic requirements for checking the performance of your water supply system, the criteria for choosing the appropriate equipment, and consider Various types pumps for increasing water pressure in mains from different manufacturers.

Comparative scale of technical characteristics of water pressure in pumps of various types

Global pump manufacturers use for the pressure characteristics of pumps different types the following units of water pressure:

For quick approximate household calculations, approximate ratios of these quantities are suitable:

In practice, for the normal operation of household hydraulic equipment with automation, the use of flow valves and the operation of bathrooms, work geysers and boilers, it is enough to maintain water pressure in the pipelines within 2-4 bar for all major models of household water devices.

Possible reasons for the lack of water pressure in the mains

The lack of water pressure in your pipelines for high-rise apartments may be due to several reasons:

Daily fluctuations in water pressure in the water supply due to the frequency of use of the resource by the residents of the house;
Lack of general user computing capacity pumping equipment from the service organization;
Temporary deposits of rust and salts inside the pipeline that clog the body of the water riser:

Clogged water filters in the water supply connection system:

In such cases, neighbors on the floor and residents of the upper and lower floors should be interviewed apartment building to find out what water pressure is usually in their apartments. This way you can identify the local cause of low pressure in your particular case. It will be possible to accept correct solution to eliminate these problems or choose the option of purchasing a high-pressure water pump individually or common use, having agreed on this issue with other residents of the entrance (riser) of the high-rise building.

In a private home, these reasons are of a similar type. But there may be various additional reasons for low water pressure in your pipeline:

Large distance from the main water supply pump;
Excessive elevation of the structure and location of the flow valves above the pump installation level;
Inconsistency between the pressure data of the power plant and the specific layout of power and consumable units, etc.

Types of water pressure boosting pumps in pipelines

In practice, you can increase the pressure in the water artery using 2 well-known types of pumps:

Insertion into the water supply main circulation pump with wet or dry rotor;
By installing an additional self-priming power unit or automatic pumping station based of this type pump

Diagrams of approximate connection of pressure booster pumps of various types:

Electric circulation pumps help in cases where it is necessary to increase the water pressure in the pipeline with a stable supply, but low pressure, reaching no more than 1 - 1.5 bar. IN multi-storey buildings With the help of this type of pump it is unlikely that it will be possible to create a sufficiently stable pressure for all residents of the riser, even if you install 2 or more pumps. This option will do more for individual increase of water pressure in separate apartment. This is, so to speak, a “home” option for stabilizing pressure.

For this reason in apartment buildings with a large number of floors, it is better to use a self-priming pump with higher capacity or a pumping station with appropriate automation for water pressure with its own hydraulic accumulator.

With this option, you will not bother yourself with the problems of turning the pump on and off; the automation will do it for you.

When installing any type of pump, it should be taken into account that if there is temporarily no water pressure at all in the taps of a high-rise building on the upper floors, then installing a booster pump will not correct this situation. The pump requires at least a minimum water pressure that meets technical limitations in order to increase it to the desired level.

If you install any booster pump only in your apartment, then keep in mind that it will create a discharge effect in the common pipeline before it. And air will be sucked into this rarefied space. It would be good if the pump was automatically protected from dry running and its motor would not burn out, but it would constantly turn off. In this case, you create an even greater pressure drop in the common water supply pipe. If other residents of your entrance or riser follow your example, this will lead to even more disastrous results with water and real “sanctions” from the water supply organization.

Self-priming pumps are limited by the amount of water rise along the installation height from the water surface to 7-8 meters (maximum 12). You also cannot install a large reservoir for a circular pump with a supply of water in a medium-sized apartment. You will have to negotiate and cooperate with your neighbors to install such a container in the attic of the house.

The most competent and comprehensive solution to these problems may be the installation of a full-fledged automatic station with a self-priming centrifugal pump. The power device must be of high performance. Contain your own hydraulic accumulator of the maximum possible volume and fully automate the water supply process. This station can be connected to the basement collector of the common riser of the general water supply or to an autonomous source. This is the only way to create the required water pressure at the outlet of all taps and not aggravate the situation for the neighbors.

Selecting a water pressure booster pump

Circular pumps are divided into 2 groups:

We are accustomed to considering circular pumps only as elements of heating systems. But they have wider applications.

Household pumps with wet rotor. They are more compact and quieter during operation. They do not require preventive maintenance to lubricate rubbing parts, since this occurs by washing the rotor shaft with water. They are easy and simple to install directly into the water supply pipe using a tie-in and do not require additional fastenings. But this group of pumps has low performance and low pressure indicators. In addition, these units are installed with a horizontal axis of the electric motor rotor.
Circular pumps with a dry rotor have an asymmetrical housing shape towards the electric motor. They are cooled by a stream of external air from a special impeller. Requires additional fastening to the wall. They have better technical capabilities in terms of pressure and performance. They require regular lubrication of rubbing parts. They create quite a loud noise when working.

Both groups are suitable for cold and hot water, but require constant manual control of the on/off mode.

To save yourself from this, you need to choose a circular pump equipped with a water flow sensor. Then the pump will start only when the supply tap is opened and there is water in the line.

The same effect can be achieved by installing a separate flow sensor on any group of circular pumps. And if the pressure in the system is unstable and there is insufficient water in the water supply, you will need to install an additional pressure switch.

Some popular models of circular pumps from global manufacturers: Grundfos (Grundfos):

Circular pumps Jemix W15GR and WP series:

Pressure booster pumps from the Wilo brand, PB and PW series

Self-priming centrifugal pumps can operate when water pressure increases, either independently or as part of automatic pumping stations.

Specialized stations for increasing water pressure from main water pipelines of the Gilex VODOMET M brand are used for inserting into the underwater part of individual sources. They have an additional flow-through filter unit for supplying already purified drinking water:

Specially created pumping units increasing water pressure from Grundfos: CMBE 3-62, 5-62, 1-44, 1-75, 3-30, 3-93 and others:

Read the instructions and install the pump

To solve a problem with water supply, you should not chase any exorbitant indicators for pressure and pump performance. You just need to add some 1.0 – 1.5 atm to the existing pressure (10 – 15 meters above the flow tap).

So you should not have any questions about how to choose a pump, what characteristics it should have. It is enough to look at the instructions for this product or listen to the recommendations of the technical manager of the store where you decided to buy the installation. The descriptions of the pumps contain all the data on their connection to the water system (connection diagram), there are rules for installing a specific product and it is described what and how to connect in the required sequence.

As a last resort, we turn to qualified specialists behind practical help for installing and setting up a pump at your dacha, cottage or high-rise building.

The problem of lack of pressure in an autonomous water supply system is not uncommon. This often happens from incorrectly selected equipment with mandatory storage tank at the top point - in this case, water flows by gravity. The system is suitable for a dacha, however, for meeting the needs of a residential building it is absolutely not rational. The pressure is not enough even for hygiene needs, not to mention the amount of equipment that requires water. In such a case, experts recommend a booster pump for the water supply system, which increases the pressure in the system.

Types of booster pumps - which one to choose

The device is a unit designed to be inserted into a system to increase the existing pressure. The parameter range is from 1 to 3 atm. The classification of these products is as follows:

Cooling type. Dry and wet rotor. The first unit is highly efficient, but noisy. The second is ineffective for numerous needs, but is quite acceptable in country gardening - watering, Summer shower, bathhouse
Switching method. Automatic and manual mode. Naturally, the first option is preferable. It is equipped with a flow sensor that monitors the operation of the device. In manual mode, you will have to monitor the heating of the pump. There are also combined models that allow, first of all, to save energy during short-term switching on.
Installation. Horizontal, vertical, in any plane. The one whose position is suitable for the water supply section is selected.
Speed. Multistage models allow you to smoothly increase the pressure in the network.
Construction type. Compact In-lines work on any section of the water supply system, but are low-power, which will affect productivity. Vortex models are noisy, require special piping, but at the same time provide proper level comfortable use of running water.
Material of manufacture. Traditional cast iron and stainless steel. The first is fragile, sensitive to water hammer and temperature changes if the pump is also used for hot water. The second one is not cheap. The material of the impeller also matters - plastic is suitable for seasonal dacha needs, bronze and brass are suitable for residential use.

Based on the classification, a choice is made. As a rule, compact built-in units with low productivity and one speed are purchased for dachas. A residential building requires something significant.

Specifications

Almost always, the specifications listed in the owner's manual indicate the maximum value. To determine the actual parameters, the values are divided by one and a half, two times. Then they make a choice in favor of one or another unit.

Details:

Maximum operating pressure . Actually, this is what the unit is bought for. For a dacha, 2 bar is enough. A residential building often requires more than 3 bar, but since the pumping equipment of a residential building is more powerful than a country house, this value is enough.
Maximum feed. The bigger, the better. Measured in l/minute or cubic. m/hour. For watering or a summer shower, an acceptable figure of 1.8 cubic meters. m/hour. For the needs of the home, the parameter is carefully calculated.
Maximum head. Regarding the well, the main work will be done by deep equipment, but it remains to bring the resource to the house, and they are often two floors. Therefore, the total height from the ground floor is taken into account.
Circuit. Pumping equipment requires an uninterrupted source of electricity. If your home network is replete with frequent interruptions, it makes sense to think about purchasing additional equipment, stabilizing the work.
Flow amount. The parameter indicates that the equipment will operate after the pressure drops by a specified amount. Smaller values will indicate best model– the pump will begin to replenish the loss with minimal water withdrawal.
Maximum and rated power. The meaning of the parameter is clear - the higher the indicators, the better pressure the booster pump will provide.
Water temperature. The range from 2 to 100 C characterizes the model as universal, suitable for a residential building. Cold water supply is often required for seasonal dachas– the summer shower is provided by an electric water heater or a collector.
Diameters of inlet-outlet holes. It is important to know in advance the area where the unit is connected, then it will be easier to select identical values. Otherwise, flanges are used during installation.

A booster pump that best suits its technical characteristics to the object and water source - considered reliable. The model and manufacturer matter for the choice. Let's see what they offer:

Top 5 booster pumps for home and garden

The Russian market is able to provide consumers with a wide selection of pumping equipment. Among the models there are budget ones and those designed for high demands. The following have gained popularity:

Boost pump Termica TL PI (Aquatic)

The cost is 3,700 rubles, which is not a burden for dacha owners. The model is powered from a 220V home network. Maximum pressure 10 m, medium temperature can rise to 60 C. Consumption 1.5 cubic meters. m/hour allows you to provide all dacha needs.

Boost pump Jemix

In addition to the dacha, it is used for apartment networks. This is especially important for owners whose meters are located above the fourth floor. Standard power supply, but an uninterruptible power supply is required - if we are talking about an apartment. Maximum temperature– 110 C, pressure 18 m. Price – 5600 rubles.

Grundfos booster pump

Leaders in pumping equipment. The price of 13 thousand rubles is most likely due to the brand, since some characteristics are inferior to inexpensive analogues - pressure 9 m, flow rate - 1.8 cubic meters. m/hour. The model uses cast iron and stainless steel, which makes the pump durable. The warranty is essential - 2 years.

Boost pump E.SYBOX

Italian manufacturer of pumping equipment for private residential buildings, cottages, production. Naturally, the characteristics are high: productivity is up to 5 cubic meters. m/hour, pressure – 50 m. Lower value of the carrier temperature – 40 C. average cost– from 35 thousand rubles.

The pump for your own needs is selected carefully. There is no point in overpaying for functions that will not be in demand at the dacha. For a house or apartment, on the contrary, a more powerful unit is required, otherwise what is the point of a running pump if it is not able to squeeze out the required amount of water?

Where to install a booster pump in the water supply system

To begin with, an installation diagram is thought out depending on the number of equipment and water collection points. As a rule, the pump is installed in front of household appliances or a boiler. For trouble-free use of water in bathrooms, the installation location will be behind the storage tank. The pump cannot operate without a bypass - a bypass line. The unit serves to increase the existing pressure, and does not completely replace the circulation pump.

Connection is easy:

The water pipe is dismantled at the insertion point.
The booster pump is installed using flanged or coupling connections, naturally, using sealing - rubber rings, fum tape and other things.
A bypass with a ball valve is welded on the same line.

Poor water pressure in the water supply is a common occurrence, especially for residents multi-storey buildings. This causes not only the inconvenience of a long wait until there is enough sufficient quantity water, but can also cause damage household appliances such as washing machines and dishwashers. And insufficient water flow in the gas water heater can lead to burnout of the casing. You can improve water pressure directly at home, for this you can: plumbing system A booster pump is installed to increase pressure.

Pump types

There are two types of boosting units, depending on the control mode:

automatic;
manual.

Automatic units have sensors in their design that detect the presence of flow in the system. When the tap is opened, the water begins to move and the sensor, reacting to this change, connects the forced pumping system. Such a pump will be able to independently provide the necessary water pressure to the washing machine and dishwasher, which themselves open the intake tap. Some automatic models have a switch from operating mode with a flow sensor to continuous pumping mode to maintain constant pressure, regardless of whether there is water consumption or not.

Manually controlled models operate only when a button is pressed, and continue to operate until switched off. This type is much cheaper, but it household use quite inconvenient. After all, in addition to opening and closing the tap, you also need to turn the pump on and off. The connected manual model will continue to operate even when there is no water in the system. As a result of dry running, it will quickly fail. In this case, automatic units will stop the operation of the injection motor, thereby protecting themselves from damage.

Depending on the type of cooling, there are models with a dry and wet rotor. In units with a dry rotor, the electric motor is separated from the direct pump housing, where the liquid is pumped. Therefore, for cooling, an impeller is used, which blows air onto the engine housing. Such models are noisier and cannot be installed in small technical niches, since there is limited air exchange, which will lead to overheating.

Models with a wet rotor use liquid that is pumped for cooling. It's much more efficient system cooling, and less noisy. The disadvantage of such models is that they are more complex requirements for electric motor repair, since it becomes necessary to remove the entire unit from the pipeline.

Selection criteria

When buying a booster pump, you need to pay attention to its capabilities in order to choose optimal model for your needs. The main criteria are:

operating temperature;
power;
method of connection to the water supply.
noise level;
maximum pressure;
throughput.

For maximum operating time, it is necessary that the unit does not operate at the limit of its temperature capabilities. So if the model’s characteristics indicate a maximum temperature of 60 degrees, then it would be better for it to work up to a maximum of 40, which will extend its life several times. If you need a pump for pumping hot water, then you can choose a model with a range of up to 100 degrees, which has a high reserve.

Engine power is a direct indicator of its energy consumption. Of course, a powerful model will easily maintain the required pressure, but at the same time consuming quite a large number of energy. Therefore, if it is necessary to slightly increase the pressure over a short distance, there is no need for an overly powerful unit.

The method of connection to the water supply also plays an important role when choosing, because in most cases the blower must be connected secretly so that it does not spoil the interior. The inlet and outlet pipes should be located in such a way as to best suit the location of the line that you have prepared for installation. In addition, the cross-section of the pipe that can be connected to the supercharger is important, especially if it is not possible to use adapters.

The noise level is especially important for use in a small apartment. If the pump is installed on a water supply in a basement, storage room or other technical room, then this criterion can be omitted, since the noise during its operation does not play a special role.

The maximum pressure is one of the most important criteria when choosing. It should be noted that power is not always an indicator of high pressure, since there are models that are quite economical in terms of energy consumption, which have high levels of generated pressure.

Throughput is a direct indicator of how fast the pump can fill the container you need. This value is measured in cubic meters/hour.

Installation Rules

For the pump to work effectively, it must be connected correctly. If it is installed in a pipeline on a common line, it will increase the pressure on all branches of the water supply system that disperse throughout the house. As a result, the created pressure away from the supercharger decreases, since it is spent on large area pipes

As a result, the pump operates at the limit of its capabilities and the effect on the final outlet of the pipes is insignificant, especially if several consumers are open at once. The solution would be to install a more powerful unit, but this will be quite unprofitable in terms of noise and energy consumption.

A more suitable and a budget option installation, namely installation on a pipeline directly in front of the consumer, for which it is important to maintain the required pressure level. So, by placing a pump on a pipe that directly leads to household appliances or a heating device, you can provide them necessary conditions work, but at the same time the pressure on other lines will remain unchanged.

In terms of savings and noise reduction, it is sometimes more profitable to install several low-power units at key consumers than one large one on a common highway. But to accurately confirm the effectiveness of such a technique for each individual case, it is necessary to measure the length of the pipes, their cross-section and the usual level of pressure that is constantly present in them. This will allow you to determine the optimal parameters as accurately as possible.

If there is running water in your home, then water should also come from the tap. However, this, unfortunately, does not always happen. Sometimes the pressure is so weak that water does not flow from the tap, and home appliances does not want to act in such circumstances. Residents of the top floor high-rise buildings often they don’t see water at all. It is for such cases that pumps are produced to increase pressure.

Causes of low blood pressure

Before purchasing a pump, a certain specification of the issue is required. Frequent questions are:

What to do if water is flowing, but there is actually no pressure?
What to do if water does not flow only to the top floor of the home; it is on the lower floors.

In the first case, the issue can be corrected by installing a pressure increase pump. The second problem cannot be corrected by a similar method, therefore, the solution is a pumping station, the purchase of which will need to be spent. The selection process is very complex and depends not only on the need for water, but also on some other components.

The problem is that before buying a pump you need to make sure that the source of absolutely all troubles is actually is low blood pressure, not clogged pipes . Because various deposits over time can significantly reduce their diameter, therefore, in this situation, even the pump may be powerless, since a change in the water supply will be required. If the issue is still low pressure, then a pressure pump will come in handy.

How to achieve perfect pressure in water pipes?

According to standards, the water pressure in the apartment should be 4 atmospheres however, differences can usually vary greatly. A coefficient of more than 6-7 negatively affects plumbing, leads to breaking of pipe joints, and low values are not suitable favorable character. If the pressure is less than 2 atmospheres, in this case the washing machine, dishwasher and flow heater supply of hot water is at risk of disruption.

The following values are used as units for measuring pressure in pipes: 1 bar = 1.0197 atmospheres = 10.19 m of water column. The minimum pressure required for the operation of many home devices ranges from 1.5 to 2.4 atmospheres; in fire extinguishing systems the requirements are higher - at least 3 atmospheres.

In case the indicators in the system are significantly lower, for example, because the apartment is on the final floor of the building, or because of the large amount of water used, in this case there is a need to use specialized means (installations) that would maintain the required pressure level. In any case, the problem should be detailed first.

Please note when selecting a device: what parameters is required for the unit?- to increase weak pressure or to raise water from the lower floor to the upper one. The main option involves equipment that is small in power and size. It is simply defined in the pipeline. For the 2nd option, you will need a centrifugal apparatus with a hydraulic accumulator. Both of them perform work in 1 of 2 modes: The continuity of operation of the equipment is determined by the manual mode.

In order for the device to work for for long years, it is necessary to prevent it from overheating Therefore, it is necessary to turn off the automatic mode in a timely manner. In this case, the flow regulator implements control. If the truck tap opens and water starts flowing, the pump turns on. This order is the most advantageous, since the pump does not turn on when there is no water, and, therefore, is protected from dry operation, which leads to the longest service life of the device. It is also customary to systematize pumping units according to the housing cooling method. It is executed in 2 ways:

using an impeller;
thanks to water pumping.

If a reason has been determined low pressure, and the problem is that the water simply does not rise to your floor, you need to purchase the most powerful device - a self-priming pumping station. Installation of the pump, which can be purchased, is carried out with or without a hydraulic accumulator. Numerous residents choose the second option, although experts insist on the first, even if the modification has a small tank.

What is a pressure boosting pumping station?

This is a simplified centrifugal device for improving water pressure; it operates with an attached hydraulic accumulator and a pressure switch, which has a control function the whole system. With the support of such a system, water is collected and supplied to the tank. Even if the pressure switch turns off the pump, the consumer still has the opportunity to drink prepared water, which is comfortable in case of frequent shutdowns. The pressure will decrease. As soon as it drops to the set level, the relay will work again and the pump will turn on. You can understand that the larger the tank, the less the load, the longer its operating period.

What to consider when choosing a unit for an apartment

Selecting equipment There are several important points to take into account:

Without knowing the required performance and pressure, it is very difficult to make the right choice. It is better to entrust all necessary calculations to a professional. Numerous companies that sell such equipment provide this service absolutely free.

If you just need to slightly increase the pressure in the system by approximately 1.5 atmospheres, in this case small pump, which you can simply buy and cut into a pipe, will fit perfectly. Some experts consider the expensive and powerful pump design to be unnecessary. In their opinion, the most rational option is a pair of devices of lower power that are connected directly in front of the disassembly points and home devices, the operation of which needs to be optimized.

Today, purchasing pumping equipment to increase water pressure is not difficult. Since it is freely presented in various shopping centers for household appliances, online stores, and construction markets. However, the best solution would be to visit a company salon, where there is the most extensive selection and there is the opportunity to receive information from a professional. After that, you will be provided with warranty service, which is especially important if the consumer purchases an expensive model.

How to install an automatic water pressure booster pump with a hydraulic accumulator?

Installing a pump with a hydraulic accumulator is not particularly difficult. This will require approximately the same skills and equipment that are needed to install other types of pumping equipment. Schematically The design of a booster pump can be presented in the form of the following steps:

Basically, a pump and hydraulic accumulator with a pressure switch involves a variation of the station. To implement the design of such a system of devices, it is first necessary to find a position for placing the tank. Certain craftsmen replace a hydraulic accumulator with a large-capacity membrane, for example, plastic tank 200 liters. Instead of a relay, the tank is equipped with a float meter to ensure that it is automatically filled according to demand. This type of tank is located as high as possible: in the attic or on the top floor.

You immediately need to think not only about volumes, but also about the configuration of the container. A flat and small tank will take less space than the classic tubular model. Although there are no specialized conditions for the configuration of the container. When choosing the position for the tank, it is necessary to calculate access to the tank/hydraulic accumulator or the likelihood of simply dismantling this component. This is necessary to perform technological maintenance, repair work or changing the device.

Hydraulic accumulators are delivered ready for installation, but the tank needs to be prepared. There are holes in it for the flow and intake of water. You can also make your own stop valve to pour out water in an emergency. The water supply pipes to the tank and its intake into the water supply system are installed to one pipe.

In modern circumstances, it is more logical to use easy-to-install and durable plastic pipes for installing water supply systems. To prevent air from being sucked into the reservoir from the pump, and also to avoid water entering there when the equipment is turned off, Opposite valves must be installed on both pipes. Subsequently, pipes are installed, with the support of which the tank is connected to the water supply system.

After the reservoir or accumulator has been installed and the required water pipes have been laid, you can start installing a suction pump. As a rule, such a device is supplied disassembled. It is first assembled, and then installation begins. If you decide to fix the pump in the wall, you must first make markings for fasteners. Then it is suspended and connected to the water supply. Overall, this is not a very complicated procedure.

An important point is the direction of water in the device. It is marked in the case with special marks. The pump must be installed in such a way that water moves from the tank to the water collection points. Similarly, the pump installation and switching diagram looks like this: hydraulic accumulator - pump - consumer. Then the pump is strengthened. All connections should be carefully sealed. After this, it is necessary to check the operation of the entire system.
