How to install a booster pump in an apartment. Pump for increasing water pressure in the country. Notable hardware manufacturers

It is difficult to find residents of apartment buildings, especially those living on the upper floors, who have never experienced the problem of poor water supply.

The same problem is often found among owners of private houses supplied with autonomous water supply. The water pressure at which all plumbing fixtures in the house will work normally is usually provided only by artesian wells, and even then not every one of them.

However, most owners of autonomous water supply use sources of low-pressure and non-pressure type, therefore they are forced to use devices in the water supply system that increase its pressure. By installing a pumping station, supplemented by a storage tank, even a low-pressure submersible pump can be used when drawing water from a well.

If the main reasons for the low water pressure in autonomous water supply systems are understandable, then why are residents of apartment buildings also concerned about such problems. Let's try to figure out why the pressure in the plumbing system, originally designed for high-quality water supply of buildings connected to a water supply source, can decrease.

To determine the reasons for
which the pressure in the system does not correspond to the norm, you should initially find out if your neighbors have complaints about this problem, or if it only affected your apartment. If the water pressure is reduced for all residents of the entrance, then the first action should be to contact the company serving the building.

It is possible that a message about an accident in the system will follow (breakthrough or leakage in the water main). If the employees of the management company claim that there is no emergency, then the next step should be to call a plumber who can professionally determine the cause of poor water pressure in the house.

Standard pressure parameters for a water supply system

In order to understand why plumbing fixtures and some household appliances may not work at reduced water pressure in the water supply, you should know what is meant by the word “norm”.

Water pressure is measured in units called BAR. Conventionally, 1 BAR is considered equal to 1 atmosphere, and 10 BAR = 1 MPa. This is the weight of a column of water, the height of which is 10 meters.

Ideally, the management company should provide a working water pressure in the water supply system of at least 4 bar.

The presence of such pressure ensures a stable supply of water even to the upper floors of multi-storey buildings and the uninterrupted operation of all household appliances. Unfortunately, a typical water supply system rarely provides a constant pressure value. Depending on various factors, pressure gauges installed to control these indicators may show from 2.5 to 7.5 BAR.

The pressure when supplying hot and cold water is regulated.

At what values ​​does household appliances work?

1. The operation of the water supply system at a pressure above the norm leads to damage to the locking devices, threaded connections. They fail at a system pressure of 6.5 BAR.
2. Reduced pressure also brings no less trouble. Washing machine will only work if the gauge shows at least 2 BAR.
3. The same indicator should be for the ability to normally take a shower, wash and wash the dishes.
4. If the house has jacuzzi or massage shower, then to use them you need not less than 0.4 MPa.
5. If there is a plot in a country house that requires watering, then in order to be able to wash dishes, take a shower and water the beds and flower beds at the same time, it is necessary to provide at least 4 BAR.

How to make plumbing in a private house with your own hands?

How to increase the pressure in the water supply system

During the construction of multi-storey buildings, the problem of water supply to the upper floors is usually solved at the design stage. For this purpose, the project of the house provides for the installation of a pump to increase the water pressure in the plumbing system. Therefore, when it drops below the norm throughout the house, it is necessary to contact the management company.

The procedure for contacting the company is as follows:

• If the company does not pay attention to previously submitted applications, then you should start solving the problem with a collective letter signed by the residents. It is drawn up in two copies, one of which must go to the management company, and the second to remain with the tenant of the house. The date of receipt of this application must be marked on the second copy.
• When submitting an application, make sure that it is registered, and on the second copy there is not only the signature of the employee who accepted the application, but also the seal of the organization. According to existing rules, residents must receive a response within a month, which should indicate the time frame for fixing the malfunction, or information about the solution to the problem.
• If the management company does not respond to the complaint, then the second copy of the letter should be addressed to the consumer protection committee. Usually, after contacting this organization, the problem is solved quickly.

Most often, the reason for the lack of normal pressure in the system is a malfunction of the high-pressure water pump, but sometimes it may be necessary to replace the pipes that supply water to the apartments. A more difficult problem is the need to repair the underground part of the water supply system, which has served for a long time.

Such a repair can be expected for many years, and the supply of a liquid with normal pressure to household plumbing is necessary today. In this case, you will have to take care of it yourself.

Features of autonomous water supply systems

The stability of autonomous water supply systems depends on the performance of the well or well. If the water flow exceeds their capacity (this situation is more common when using non-pressure wells or wells), then the pressure in the system may become insufficient.

The water pressure at which all plumbing fixtures in the house will work normally is usually provided only by artesian wells, and even then not every one of them. However, most owners of autonomous water supply use sources of low-pressure and non-pressure type, therefore they are forced to use devices in the water supply system that increase its pressure. By installing a pumping station, supplemented by a storage tank, even a low-pressure submersible pump can be used when drawing water from a well.

In the case of using high-capacity wells, the pressure in the system may rise above the permissible limits, which leads to its damage and premature wear of plumbing equipment.

To avoid this situation, you should choose the right pumps for wells. The equipment must correspond to the productivity of the well and the daily consumption of water during the period of its maximum flow.

Ways to increase pressure

Installation of a pumping station and possible malfunctions

Today there is a fairly extensive range of equipment designed specifically for this purpose. One of the ways to ensure the possibility of obtaining the necessary water pressure in the system is the purchase and installation of a pumping station.

Typically, this set of equipment is used in private homes, since when installing it in an apartment, many problems arise:

1. One of them is the need allocation for its installation of sufficient area, which in most cases is difficult, since the station equipment consists of several elements. Especially a lot of space is occupied by a hydraulic accumulator equipped with an electric motor. In addition, you will need space for filters, sensors, piping and a system control unit.
2. However, obtaining normal pressure in the water supply is so important that homeowners are able to find a place for a pumping station using a minimum of space. But here another problem arises - after the installation of such equipment, water in the apartment will definitely appear, but the neighbors may disappear altogether. For this reason, this type of installation pump for increasing water pressure in the apartment requires agreement with the management company.

The pumping station is not gaining pressure - what to do?

There are situations when the pumping station does not gain pressure, but at the same time it works and does not turn off. There may be several reasons for such a malfunction:

1. The pressure in the pumping station does not rise due to insufficient voltage in the network. If the voltage does not correspond to the value specified in the characteristics of the pump, then it will not be able to produce the pressure necessary for the operation of the system. In this case, using a good voltage stabilizer or purchasing a more powerful pump can help.
2. The cause of the malfunction may be incorrect pressure adjustment of the pumping station. Pressure switch can be adjusted using the nut found on the smaller spring. When it is unscrewed, the upper pressure indicator will decrease, and the station will turn off on time.
3. It is also possible that the pump may fail due to impurities present in the water. To avoid its breakdown, you should purchase equipment that has a special filter insert in the working chamber. A leak in a pipeline or a non-return valve is difficult to notice, but it is also one of the common causes of workstation malfunction.

When choosing the equipment necessary to increase the pressure in the water supply system, you should definitely consult a specialist. Only a professional who knows the capabilities of such equipment well will be able to help in choosing a way to increase the pressure in an apartment, or in a private house.

Inclusion in the circuit of an additional centrifugal pump

A more realistic way is to install a centrifugal pump at the inlet of the pipeline to the apartment, designed to increase the water pressure. Its installation is carried out if water enters the apartment, but in an extremely small amount, insufficient for the operation of household appliances.

Centrifugal pumps of this type are available with two modes of operation:

1. It can be controlled manually, turning the unit on and off as needed.
2. When using automatic mode, it starts after opening any tap in the apartment.

The beginning of the operation of the device provides a flow sensor included in its design. When the liquid begins to move through the pipe, a signal is sent from the sensor to turn on the unit. Closing the tap serves as a signal to turn it off. The presence of such a sensor becomes a protection against burnout. For this reason, devices equipped with a flow sensor are the most popular.

Centrifugal pumps for increasing the water pressure in the apartment are divided into two types according to the method of their cooling:

1. dry rotor equipped with an impeller located on the motor rotor. The impeller blades direct the air flow to the motor, thereby cooling it. These pumps operate with low noise and have high efficiency;
2. during pump operation wet rotor The water flowing through the unit is used to cool the engine. The main advantage of using them is their silent operation.

When purchasing a centrifugal pump, it should be borne in mind that there are universal pumps, and there are those that can only be used in cold or only in hot water supply. A pump installed at the inlet of the water supply to the apartment, immediately after the water meter, can increase the pressure by 1-3 BAR.

Partial modification of the system with flexible fittings

There are situations when the pressure is not enough for a particular device. In this case, the pump can only be installed on this device.

It often happens that the water pressure is not enough to operate the boiler. There is cold water in the apartment, but there is practically no hot water. To pass through the heating device, the pressure existing in the water supply is not enough. In this case, you can choose a place for installing a water pressure booster pump directly in front of the household appliance.

If soldering skills are required to install a pump that increases pressure at the inlet to the system, then using a pump for a specific device is much easier. It is attached to the plumbing fixture using flexible fittings. First of all, you need to choose the right centrifugal pump.

When choosing, consider:

1. The maximum pressure of the pump must not exceed the allowable pressure value of the device to which the pump will be connected.
2. At the inlet and outlet, the pump must have a thread for connecting a flexible connection.
3. Together with the pump, a ball valve and a flexible hose are purchased, equipped with a thread corresponding to the thread on the device.
4. If the thread does not match, then the necessary adapter is purchased.
5. Be sure to purchase a fum tape designed to seal threaded connections. To determine the length of the hoses, the installation location of the pump is determined in advance.

Installing an additional booster pump

1. A flow sensor (dry running) is installed at the pump outlet. For ease of determining the correct location of the sensor, the pump has a designation of the direction of fluid movement. The plug on the sensor is inserted into the connector of the control unit.
2. The pump is installed in the place intended for it and fastened with self-tapping screws as indicated in the instructions in order to avoid failure of the bearing.
3. Mounting is carried out in such a way that there is no vibration during pump operation.
4. Then the hoses are mounted using threaded connections. During installation, use the sealing tape and rubber gaskets supplied with the pump.
5. The entrance to the pump from the water supply is carried out through a pre-installed shut-off valve (ball valve), and the pump outlet is connected with a flexible hose to a plumbing fixture that needs to increase pressure. In this case, it is necessary to ensure that the hose does not have sharp kinks.
6. The first start-up of the unit is carried out in manual mode. After the start of its work, all connections are checked.
7. If leaks are detected after the pump is turned off, the leak is eliminated and the operation is checked in automatic mode. To do this, the required mode is set on the control panel and the tap of the plumbing fixture is opened.
8. After filling the pump with water, the pump will start to work, which will be noticeable by the increased jet. It will turn off after the tap is closed.

The sensor may not work if the head is extremely low. In this case, you will have to switch to manual mode.

In case of insufficient amount of water (most often this problem occurs when it is taken from wells and non-pressure wells), experts recommend purchasing a storage tank (hydraulic accumulator). Its use will allow you to accumulate water in the tank, using it when necessary.

A hydraulic accumulator installed in a private house is best placed in a heated room.

Prices for works, equipment and materials

• At pumping stations and pumps that increase pressure, the price is also not too high. Pump cost starts from 4 thousand rubles and reaches 9 thousand rubles.
• For purchase pumping station will have to allocate 6 - 15 thousand rubles.
• Depending on the design hydraulic accumulator and its volume, its purchase will cost within 2 - 12 thousand rubles.
• If the installation of the units will be carried out by specialists, then the total cost of installation work will be approximately 20% of their cost. You can find specialists who work a little cheaper.

Perhaps the main parameter in modern is the level of pressure. A comfortable level of water pressure in the pipes allows us to operate the entire system without any problems. If there are problems with this in the water supply, then they automatically affect its performance.

But what if there is not enough water pressure in the water supply? The answer is very simple. Install pressure pumps.

1 Features and purpose

As we all know, modern plumbing in an apartment or a country house consists of several basic structures or elements. Perhaps the most important of them is the pipeline itself.

Through the pipeline, water flows to the taps, which can then be obtained in any place suitable for this. The pressure in the system is responsible for the free flow of water through the pipes. According to European standards, the pressure in the water supply system should be at least 4-5 atmospheres.

This is due to the necessary requirements that are provided by various additional plumbing fixtures. So, the washing machine will not be able to function if the water pressure in the system is not equal to 2 atmospheres. It just won't start.

Pressurized showers and a variety of whirlpool baths require even more serious conditions. They can already be operated normally if the water pressure in the water supply system is at least 4 atmospheres. Various devices for hydromassage are not limited to the declared characteristics.

As you can see, serious requirements are imposed on the conditions in a modern water supply system. And they don't always answer them. So, in an average apartment, the water pressure in the water supply system can be only 2.5-3 atmospheres. Good pressure also happens, but here it rather depends on the quality of the equipment that serves the apartment building.

In country houses, cottages and mansions, the situation is complicated by the fact that people have to deal with the creation of local water supply systems on their own. And not always one single pump is able to provide normal conditions in the water supply. Especially if the pipe laying scheme was planned erroneously or in violation of certain standards.

There are also extreme cases when the pressure level in the water supply system has not just dropped. It is simply not there, since the water does not reach the consumer. For example, if the riser is too long and the inlet booster pumps are not able to raise the water to a sufficient level.

2 Types and characteristics

As you can see, pressure boosting pumps have different designs and in this parameter they are very different from each other. To begin with, consider their main division according to the type of design and purpose. According to these parameters, they are divided into:

• increase in pressure level;
• Self-priming booster pump stations for water supply systems.

The first variety is a standard booster pump. It is called circulation because of its contribution to the circulation of fluid in the pipes. The device has, as a rule, small dimensions and is very compact. It is cut into a certain section of the pipeline, which increases the pressure level and the fluid circulation rate on it.

Initially, these pumps were conceived for arranging hot water and heating systems. This is due to the serious length of the heating circuits, as well as their resistance at the nodal connections.

Under natural conditions, the carrier simply cannot circulate normally in the water supply system, so a special pump is used to increase the pressure.

In a standard water supply, the situation is similar. It's just that here the device is already used not so much for pumping hot liquid, but for stimulating the general level of water movement.

The circulator consists of a small motor that rotates the rotor part with an impeller. It is this small mechanism that is able to pump water into the chamber and significantly improve the performance of the entire pipeline.

The most popular pressure booster pumps are manufactured by Wilo. In particular, the Wilo TOP, Wilo Star-RS, Wilo Star, etc. lines.

Now let's turn to the second type of booster pumps. This is a much more serious unit that cuts off the water supply system from external recharge.

2.1 How to choose booster pumps?

If you need to choose a household pump to increase the pressure in the pipeline, then you should be guided by dry calculations and the specific characteristics of the equipment. To begin with, it is recommended to contact a specialist to assess the condition of your system.

As a last resort, measure the pressure yourself. This will help you select the optimum capacity water pumps. After all, there is no point in overpaying for too powerful equipment, which in your case simply cannot reach its potential.

A circulation sample to increase pressure is worth buying if you have water in you, but its pressure is too weak. Moreover, to level the lack of 2-3 atmospheres, one sample is enough. In some cases, it is necessary to install two pumps. But this happens quite rarely.

Pumping booster stations should be chosen if you don’t have tap water at all, but lower in level in the system (for example, neighbors below, if you are a tenant of an apartment building) have it.

In this case, a self-priming pump will pump fluid to your level, and a hydraulic accumulator will completely close the system and give you the opportunity to control its condition yourself.

Of the popular manufacturers, it is better to buy pumps or Grundfos. Since Wilo companies have proven themselves in the market from the best side and are time-tested.

2.2 Features and connection technology

Pumps for increasing the pressure in the water supply are mounted quite easily. As a rule, they are embedded at the entrance to the system so that the stimulation of fluid movement takes place as conveniently and efficiently as possible.

So, circulation models are cut into pipes in a certain area. All you need is to connect the device to the pipes, seal the connections and supply electricity. Then it remains to test the operation of the device in practice.

It is worth remembering that circulation models must be mounted in a single position. The correct position will be indicated by the manufacturer on the packaging. If you install the device by mistake, it will either work poorly or refuse to start at all.

2.3 How is the pump installed? (video)

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

Causes of low pressure

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

1. What to do if water is pouring, however, there is actually no pressure?
2. What to do if water does not flow only to the upper floor of the housing, it is on the lower ones.

In the first case, the issue can be corrected by installing a pressure increase pump. The second trouble is not corrected by a similar method, therefore, the solution is a pumping station, the acquisition 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 pressure, not clogged pipes. Because different deposits over time can greatly reduce their diameter, therefore, in this situation, even the pump may be powerless, since a change of water supply will be required. If the issue is still in low pressure, in this case the pressure pump will come in handy.

How to achieve perfect pressure in water pipes?

According to the standards, the water pressure in the apartment should be 4 atmospheres, however, usually the differences can vary greatly. A coefficient of more than 6-7 negatively affects plumbing, leads to breaking of the pipe connection, and even low values ​​\u200b\u200bare not favorable. If the pressure is less than 2 atmospheres, in this case, the washing machine, dishwasher and instantaneous heater for supplying hot water are threatened with failures.

The following values ​​​​are used as units for measuring pressure in pipes: 1 bar \u003d 1.0197 atmospheres \u003d 10.19 m of water column. The smallest 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.

If the performance in the system is significantly lower, for example, because the apartment is located on the final floor of the building, or because of the large water intake, in this case, there is a need to use specialized tools (installations) that would maintain the required pressure level. In any case, at the beginning, you should detail the problem.

It must be taken into account when choosing a device, with what parameters the unit is required- to increase a 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 dimensions. 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: Continuous operation of the equipment determines the manual mode.

In order for the device to work for many years, must be prevented 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 crane opens and water starts to run, then 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 method of casing cooling. It is performed in 2 ways:

• with the help of an impeller;
• due to water transfer.

If the cause of low pressure has been determined, and it is that the water simply does not rise to your floor, you need to purchase the most powerful device - a self-priming pumping station. The installation of the pump, which can be bought, is carried out with or without a hydraulic accumulator. Numerous residents choose the 2nd option, although experts insist on the first even if the modification has a small tank.

What is a booster pump station?

This is a centrifugal simplified device for improving water pressure, it operates with an attached hydraulic accumulator and a pressure switch, which has the function of controlling the entire system. With the support of such a system, water is taken, which is fed into the tank. Even if the pressure switch turns off the pump, the consumer still has the opportunity to use the prepared water, which is comfortable in case of frequent shutdowns. The pressure will then decrease. As soon as it drops to the set mark, the relay will work again and the pump will turn on. It can be understood that the larger the tank, the lower the load, the longer its period of operation.

What to consider when choosing a unit for an apartment

Choosing equipment, There are a few important points to keep in mind:

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

If it is only necessary 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 the pipe, will fit flawlessly. Some experts consider the construction of an expensive and strong pump unnecessary. In their opinion, the most rational option is a pair of devices of lesser power, which are connected directly in front of the parsing points and home devices, the work of which needs to be optimized.

Today, it is not difficult to purchase pumping equipment for raising water pressure. Since it is freely represented in various shopping centers for household appliances, online stores, and construction markets. However, the best solution would be to visit a branded salon, where there is the most extensive choice, it is possible to obtain information from a professional. After that, you will be provided with a mandatory 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?

Installation of a pump with a hydraulic accumulator is not very difficult. This will require approximately the same skills and devices that are needed to install a different type of pumping equipment. Schematically the design of the booster pump can be presented in the form of the following steps:

According to the essence, a pump and a hydraulic accumulator with a pressure switch assumes 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 the hydraulic accumulator with a large-capacity membrane, for example, with a plastic tank of 200 liters. Instead of a relay, the tank is provided with a float meter to ensure its self-acting filling according to the need criterion. This kind of tank is determined as high as possible: in the attic or on the top floor.

Immediately it is necessary to think not only about volumes, but also about the capacity configuration. The flat and small tank will take up less space than the classic tubular model. Although there are no specialized conditions for the configuration of the tank. When choosing a position for the tank, it is necessary to calculate access to the tank / accumulator or the likelihood of a simple dismantling of this component. This is necessary for the performance of technological maintenance, repair work or change of fixture.

Hydraulic accumulators are brought ready for installation, but the tank must be prepared. It has holes for water inlet and outlet. You can, in addition, make an independent shut-off valve to pour out water in an emergency. Branch pipes for supplying water to the tank and taking it into the water supply system are installed to one pipe.

In modern circumstances, for the installation of a water supply system, it is more logical to use easy-to-install and durable plastic pipes. In order to prevent air from being sucked into the tank from the pump, and also to avoid water entering there when the equipment is turned off, it is necessary to define opposite valves on both nozzles. Subsequently, pipes are installed, with the support of which the tank is connected to the plumbing system.

After the tank or accumulator is installed, and the required water pipes are laid, the installation of a suction pump can be started. As a rule, such a device is delivered unassembled. It is first collected, and then proceed to installation. If the decision is made to fix the pump in the wall, you must first make markings for fasteners. Then it is suspended and connected to the water supply. In general, this is not a very complicated procedure.

An important point is the direction of the water in the device. It is marked in the case with special marks. The pump must be installed in such a way that the movement of water is from the tank to the water points. Similarly, the scheme for installing and turning on the pump looks like this: a hydraulic accumulator - a pump - a consumer. Then the pump is strengthened. All connections must be carefully sealed. After that, you need to check the operation of the entire system.

Which is better?

The market for water pressure pumps is wide and varied. It presents a huge number of products of manufacturers from different countries. The following modifications are better known:

Sprut 15WBX-8

Household silent pump is a pressure boosting unit offered at an affordable price, designed for installation in an apartment. Has the following data:

• cooling method - dry rotor;
• the order of work is automated;
• lowest inlet pressure 0.3 bar;
• working pressure, no more than 6 bar;
• performance not more than 0.09 kW;
• efficiency not less than 8 l/m;
• the largest mass is 2.24 kilograms.

Aquatica 774715

The household automatic pump is designed for use as a pressure booster in a private house and has an affordable price. It is recommended to maintain the pressure required to ensure the efficiency of gas water heaters, washing machines and dishwashers. Characteristics:

You can buy a high-quality pump to increase water pressure in building materials markets, special outlets for the sale of plumbing, and, in addition, with the support of functioning stores on the Internet. Wherever pumps are sold to increase water pressure, a potential consumer can familiarize himself with the operational parameters and obtain qualified advice on absolutely all issues of interest to him.

Plumbing is part of the engineering networks of a private house and apartment. Due to the weak pressure in the pipes, residents often receive an insufficient amount of water. This situation limits the ability to use two plumbing points at the same time, and the washing machine and dishwasher simply do not turn on. The only way to make a difference is with a pumping station designed to increase water pressure. The power and performance of the installation is selected individually. The compact device is able to normalize the level of pressure and maintain an optimal indicator.

For the city water supply network, the accepted GOST standards assume a pressure of 4 atmospheres. Such an indicator is rare, seasonal changes in water consumption make it fluctuate in the range of 2.5-7 atmospheres. The normal operation of the shower, washing machine and sink will provide a parameter of 2 atmospheres, a jacuzzi or watering the garden will require raising it to 4. In reality, the pressure is often 1-1.5 atmospheres, excluding the stable operation of plumbing equipment. High pressure is also a negative factor, it negatively affects the elements of the network, leading to their rapid wear.

The problem of insufficient water supply is faced by residents of apartments on the upper floors and owners of private houses in the summer. First of all, it is necessary to exclude the possibility of clogging of pipes or their overgrowth with lime deposits. If the problem is not in the diameter of the pipes, then the installation of pumping equipment will radically solve the issue. The pumping station will raise and stabilize the pressure in the system.

Classification of pumping equipment

A budgetary way to increase the pressure in the water supply of an apartment or a private house is to install a pressure pump. Devices can be divided into main groups:

• manual - after being connected to the power supply, they are constantly in working order. 24/7 operation leads to rapid wear. If there is no water in the system, the device may burn out;
• automatic - the design provides for a sensor that turns on the unit when the fluid moves. This option will cost more, but will last longer. The equipment is designed for pumping clean water, so it is better to equip the system with a coarse filter. The low weight and dimensions of the pump allow it to be installed directly on the pipeline.

The pump motor is cooled in two ways:

• the flow of passing fluid;
• fan mounted on the motor shaft.

On the basis of water-lifting pumps, stations for increasing water pressure are produced.

If the liquid in the pipes is often completely absent, it will be necessary to upgrade the system and install a self-priming mini pump station. This compact device is able to increase the pressure and keep it at a given level.

Equipment design includes:

• storage tank of membrane type (hydraulic accumulator);
• centrifugal pump;
• system control relay.

The system automatically supplies water to fill the tank. The consumer uses the liquid accumulated in the accumulator. The main advantage of such a system is the prevention of pressure surges in pipes. In addition, the mini station provides a supply of fluid in the accumulator, which can be used at any time.

With a drop in the water level, the pressure in the system decreases; at a given indicator, the relay turns on the pump again. The number of inclusions and the life of the pump depends on the volume of the tank, the larger it is, the less often the electronics that bring the unit into working condition are triggered. The area of ​​​​the apartment is limited, so it is problematic to find a place for a volumetric tank, in addition, the absorption of water by the equipment leads to airing the system. Installing a pressure boosting station without the permission of the public utility is illegal, and it will not be easy to get approval, so installing a booster pump is preferable.

How to choose the right unit

Among the main criteria for choosing a mini station to increase the pressure in the system:

1. Productivity - the amount of water that the installation pumps per unit of time (minute, hour).
2. Power - is selected based on the number of consumers. A high score is not always a plus. The station sucks water from a source (well, pipeline), if the pump runs faster than it is being filled, then the unit may be left without liquid and overheat.
3. Compliance of the model with the cross section of pipes in an apartment or a private house.
4. Maximum lifting height. This indicator is important for the use of equipment for autonomous water intake of a private house and for pumping water to the upper floors of an apartment building.
5. Unit size. The dimensions of the station, including the accumulator, must correspond to the area of ​​\u200b\u200bthe room where it will be installed.
6. Noise level. This criterion depends on the cooling method, the "wet rotor" works silently, and the "dry rotor" is noisy due to the fan blades.
7. Permissible temperature range. Devices can be for hot, cold water or universal.
8. Installation type - vertical or horizontal, the choice depends on the characteristics of the room.
9. Manufacturer's reputation. Products of unknown companies are distinguished by an attractive price, but their quality is doubtful, and there are no service centers. It is better to buy high-quality and reliable equipment from a manufacturer with positive reviews.

DAB offers a compact electronically controlled station E.sybox mini for installation in an apartment or house. It is distinguished by the absence of noise and vibration, provides a constant pressure in the pipes, and is easy to install. Lifting height - 8m, productivity - 80 l / min, membrane tank 1 liter. The mini unit is easily placed under the sink.

The model of the German company Wilo PV-088 EA is mounted on metal pipes for hot and cold water supply. The maximum head lift is up to 8 m, it works in manual and automatic mode. The mechanism is cooled by fluid flow. Low noise level allows you to avoid discomfort when placed in an apartment.

The Grundfos UPA 15-90 pump operates in three modes: Automatic, Manual, Off. The automatic mode is controlled by a built-in sensor. Manual mode involves constant operation, so you need to monitor the presence of water in the system. The unit is characterized by low noise and low weight. Its capacity is up to 1.5 cu. m / h, working temperature - 60º C.

Unlike the listed models, the Jemix W15GR booster pump operates on the “dry rotor” principle. The mechanism is cooled by a built-in fan. This design is more productive, but creates noise during operation. It has three operating modes: "MANUAL" - manual, "AUTO" - automatic, "OFF" - off. Provides head lift up to 10 m, productivity - 1.5 cubic meters. m/h

Mounting the booster pump

The installation of pressurization equipment begins with shutting off the water. The work includes the following steps:

1. The length of the pump is measured along with the fitting.
2. At the installation site, the length of the section is marked and the pipe is cut out.
3. From the outside of the resulting ends, a thread is cut.
4. Adapters of the required diameter are installed, a fitting supplied with the pump is screwed to them. On the body of the equipment, the arrow indicates the movement of the flow, it is important to install it according to the given direction.
5. To install a separate outlet, a three-core cable is pulled. Grounding is mandatory, and the connection is made through the RCD.
6. The water opens and the pump is tested to see if it works. If the connection of the fittings is not tight enough, wind up the FUM tape.

DIY station

If there was no device with the necessary parameters on the counter, you can make it yourself from components with the desired characteristics. The pressure boosting station consists of a small number of components and parts, it is enough to purchase a pump, a hydraulic accumulator of the required volume, and an automation unit. A 50-liter storage tank is suitable for a family of three; stagnant water is also undesirable.

The control system should include:

• smooth start of the pump;
• dry running protection;
• overload protection.

During installation, all elements of the water pressure increase station are installed in one place.

Tips for choosing and installing a mini pumping station

1. Give preference to the model with a check valve, this design increases the safety of the equipment.
2. Choose a station with a built-in filter, it will protect parts from foreign particles. When clogged, the element is removed and washed.
3. To accommodate the equipment, you need a warm room, otherwise, at a negative temperature, the water in the accumulator will freeze.
4. To carry out preventive maintenance without problems, install a shut-off valve before the pump.

With a centralized supply of water to apartments in multi-storey buildings, residents of the upper floors may experience inconvenience due to weak water pressure. For the normal operation of a washing machine or dishwasher that heats the water of a geyser, pressure in the plumbing system is required from two to four atmospheres. At lower pressures, this technique will not work. And a weak stream from the tap, or the complete absence of water, is not at all pleasing, if necessary, to wash the dishes or take a shower. In order to normalize the situation with water supply, residents of high-rise buildings should use pumps to increase the water pressure in the apartment.

Installing a pump in an apartment will be required only if the cause of insufficient pressure is not clogged water pipes, but other problems, the solution of which requires a global modernization of the water supply of the entire house.

1 The need for installation

Own water pumps in the apartment are installed to create and maintain an acceptable working pressure, taking into account all points of water consumption. With the simultaneous use of a water resource in several places, a natural decrease in pressure occurs in the overall system.

Normal pressure for an apartment with domestic use of water is considered to be four atmospheres. This is enough to prevent failures in the operation of the washing machine, shower, jacuzzi, geyser, which have automatic shutdown of the device in case of insufficient pressure.

Increased pressure may occur. An indicator of seven or more atmospheres leads to damage to household appliances and individual elements of the water supply.

With a technically competently calculated and normally installed water supply system in an apartment building, situations arise with pressure drops due to peak consumption. For example, in the evening, when most residents come home from work and start doing household chores, water consumption rises sharply. This leads to an annoying situation when everything is in order on the lower floors, and even washing your hands is problematic upstairs.

A pump for increasing water pressure, mounted directly on the supply line, is able to provide complete and stable comfort of using water at any level of a multi-storey building.

2 What should you pay attention to?

The water pump installed in the apartment can have two types of control:

• manual - requiring constant monitoring during operation of the pump;
• automatic - the operation of the device is regulated using special sensors (pressure, pressure, flow).

Installing a manually operated water supply device is advisable if it is not used regularly. And human control is necessary to prevent the pump from running dry. If there is no water in the central water supply, the electric motor will overheat and burn out.

Pumps with automatic control do not require any attention. They can be switched on all the time, as their work is regulated by automation, depending on the situations that arise.

The temperature of the water in the central water supply is also important, since individual models that increase pressure can work as follows:

• only with cold water;
• only with hot water;
• both cold and hot (universal device).

An important factor in the operation of the unit maintaining water pressure in the apartment is the way it is cooled:

Air-cooling causes increased ambient noise, but the performance of such a device is higher than that of its water-cooled counterpart, which is almost silent. It is used in pipelines for both cold and hot water.

2.1 Important features

Since the water pump will be installed directly in the apartment, some of its characteristics should be taken into account:

• power - the higher it is, the more points of consumption will be provided with sufficient pressure;
• Noise level is an important factor to consider in order to maintain a comfortable noise environment in the apartment. Too noisy units are not suitable, especially when working at night;
• the diameter of the pipes brought into the apartment - an increase in pressure is possible only if the cross section of the pipeline and the pump nozzles are in full compliance;
• lifting height - each pumping unit is designed for a certain height of liquid delivery;
• overall dimensions - for an apartment that has limited space for installing this kind of equipment, compact units should be selected.

3 Installation in an apartment

Installing a pressure booster pump in a domestic pipeline will provide all domestic water needs for a long time.

In order for the equipment to work smoothly, you should use the following recommendations:

• the flow of liquid into the pump must occur through a coarse filter. Thus, the ingress of solid particles through the water into the unit, which can cause mechanical damage, is excluded;
• location only in a dry and heated room, to prevent the corrosive effects of moisture and the negative effects of low temperatures;
• the obligatory presence of a shut-off valve (cock) installed in front of the pump, which will allow carrying out preventive and repair work when disconnected from the central system;
• reliable fastening - will ensure the absence of leaks caused by constant vibration of the operating unit.

Installation of equipment that can increase the water pressure in the apartment occurs as follows:

• the supply of water to the apartment is blocked;
• a marker on the carrier pipe selected for installing the pump makes marks, taking into account the overall dimensions along the length and the presence of adapters;
• a pipe is cut in the marked places;
• on the outside of the free ends of the pipe, a screw thread of the desired pitch is cut;
• adapters with internal threads are screwed onto the ends of the pipes;
• adapters are completed with fittings;
• the pump is installed in compliance with the correct direction of fluid movement indicated by the arrow on the device case;
• a three-core cable is wired from a household power source;

At the end of the installation work, it is necessary to conduct a test run of the device to check for leaks in the connections. For absolute sealing, it is recommended to use FUM tape, winding it around the threaded connection.
