Contemporary public utilities often does not provide the supply of water of the required parameters to the common line. A pump to increase the water pressure in some cases would be useful. But the choice of device depends on many factors. Sometimes a complex solution can save the situation.

Technical parameters of water supply laid down in the regulations

Modern household appliances are designed for water supply with a pressure of 4 bar. If the pressure in the tubes is less, the devices turn off. You can check the pressure on the pressure gauge or using homemade device- a transparent tube 2 m long connected to a tap.

equivalent physical quantities pressures are recognized: 1 bar, 1at, 10 m of water. Art., 100 kPa. Such indicators can be found in the passports of the pumps.

The normal pressure is considered to be the pressure for which pipes, joints, gaskets are designed - 4 bar. At 6-7 bars, leaks appear in the line, at 10 bars the pipes can break. You need to know this when choosing a pump to increase water pressure.

Is it always possible to install booster pumps

In a private house, the lack of pressure in the line is stopped installed pumps. At the same time, their power supply through the battery tank allows you to have stable input parameters. Mount devices in areas where you need to increase the pressure after the pump. The pump for increasing the water pressure differs from the centrifugal one in that it turns on periodically, upon request. The centrifugal apparatus in the system is constantly running.

V apartment building There may be several problems:

• in the manifold on the distribution comb is not desired pressure for any reason;
• during peak periods, water upper floors comes with intermittent flow;
• In the apartment at different points the pressure is different.

Examinations should show the reason for the lack of pressure. There are cases when the pressure in the line is normal, but the downstairs neighbor narrowed the conditional passage when replacing pipes. It happens that the pipes are completely clogged with rust. In such cases, it is useless to install a pump to increase the water pressure in an apartment with a common wiring. It is necessary to restore the conditional passage in the system.

A legitimate way out could be to install an accumulator tank in the basement, a common riser, then all residents can use a pump that increases the pressure in the water supply on a common line.

At general lack water in the system, it is forbidden to install an additional pump to increase pressure, penalties are comparable to the cost of the equipment.

Pump Selection Criteria

First of all, a pump is selected based on the outlet pressure indicator, about 4 bar. It is important to know the dimensions, wet or dry rotor, noise. When choosing a pump high pressure the determining factor may be the presence of automation or manual control.

Used for hot and cold water supply different systems pumps. Cold water systems are equipped with pumps from well-known manufacturers:

1. WILO - the booster pump is recognized as the most purchased. Differ in simple device, reliability and long term guarantees.
2. – works silently, in demand, warranty is issued for 1 year
3. OASIS is a brand that strives to get into the TOP, and so far it succeeds due to simple device, reliability and low price.
4. Gileks is a recognized domestic leader in the production of pumps.

Their models are compact and quiet. Branch pipes for installation are unified for Russian water utility systems.

Pumps to increase water pressure are of two types, with a "wet" and "dry" rotor. Devices with wet rotor installed in the pipe. The power part is located outside the pipe, has air cooling, is attached to the wall as a cantilever - a pump with a dry rotor.

The high pressure water pumps on the manifolds run continuously. More often they are equipped with more than one, several wheels, the pressure increase occurs in steps. Such devices can create a pressure of several tens of atmospheres on the injection line. Industrial plants high-pressure models are only available with a free-standing air-cooled engine.

Installation of the pump in the apartment

First you need to carry out the distribution of water to devices that need a stable pressure. Installing the pump before wiring will make it possible to get by with one device, which is turned on manually or automatically.

Before starting work, make sure that the reinforcement does not let the agent through. To guarantee the common cold water riser must be blocked from the collector.

Steel pipes should be welded by a professional welder. Polypropylene conduits are connected with special fittings, a soldering iron is required. Be sure to install shut-off valves before and after the pump.

It is important to correctly position the high pressure water pump impeller in the direction of fluid flow, as indicated by the arrow. A common booster pump can be installed immediately after the root valve, then the pressure is maintained at all points of extraction. After checking the system for tight connections, the pump is plugged into the outlet.

Using the accumulator tank and high pressure pump

Such a scheme would be required if high-rise building chronically lacking pressure on the upper floors. Turning on the high pressure pump is due to an increase in the flow rate on the line to a certain value. Since pressure and flow are interdependent indicators, an increase in flow is a signal to turn on the high pressure pump.

When turned on, the pump will create required pressure in the system on all floors. Thus, it is possible to solve the problem of water supply for residents in a cottage or multi-storey building.

booster pump cost

The market offers models of pumps for increasing water pressure at a price corresponding to the prestige of the brand, the degree of automation, and parameters. The minimum pump costs 2500 rubles. Brands that work on the principle: set it and forget it, can cost 30,000 rubles.

Industrial installations for highways are purchased by agreement. In any case, the installation of a high-pressure pump will require a survey of pipes and an installation project approved by the Housing Office.

Video about the operation of the booster pump in the water supply system

If the house has running water, it is logical to assume that it has water. But, unfortunately, this is not always the case. Sometimes the pressure is so weak that Appliances, unable to withstand such a test, simply refuses to work, in high-rise buildings water often does not reach the upper floors at all, stopping at lower levels. It is in such situations that pumps will come in handy to increase the water pressure in the system.

How to achieve ideal pressure in water pipes?

Several values ​​​​are used as units for measuring water pressure in pipes: 1 bar \u003d 1.0197 atmospheres \u003d 10.19 m of water column. According to the regulations, the pressure in urban water supply networks should be 4 atmospheres, but the reality is that the differences can be very significant. Pressure of more than 6-7 atmospheres has a detrimental effect on sensitive imported and domestic plumbing, destroys pipe connections, but even low pressure causes no less trouble. At a pressure of less than 2 atmospheres, neither a washing machine nor a dishwasher can work normally, not to mention a Jacuzzi.

Minimum pressure required to operate most household appliances, ranges from 1.5 to 2.4 atmospheres, in fire extinguishing systems the requirements are more serious - at least 3 atmospheres. If the indicators in the system are much lower, for example, because the apartment is located on the top floor of the building, or because of the large water intake, then it becomes necessary to use special means(increasing installations) that would maintain the required level of pressure.

Before selecting a high pressure pump, it is necessary to specify the problem. The most frequent complaints are:

• tap water flows, but the pressure is so weak that there is no question of any comfort;
• There is no water only on the upper floors of the building, on the lower - everything is in order.

In the first case, a water pressure booster pump can serve as a solution to the problem. In the second, he will be powerless, he will have to fork out for the purchase of a self-priming unit.

A pumping station can solve pressure problems in most cases, but you need to know how to connect this equipment

The choice is very individual, depending on the need for water and a few more important factors. Before doing this, you need to make sure that it is precisely in insufficient pressure, and not in clogged pipes, because, thanks to lime deposits or mechanical particles, the diameter of the pipes can become much smaller over time, then the pump will not help, the water supply will need to be replaced. If the problem lies, indeed, in a weak pressure, then the equipment will be useful.

Model classification

So, when choosing, consider whether you just need to strengthen weak pressure or to understand the water from the lower floors to the upper ones. In the first case, you will need a small device in terms of power and size, of an “in-line” design, which is simply mounted in a pipeline, in the second, a high-pressure centrifugal water unit with a hydraulic accumulator. They operate in one of two modes:

• Manual mode - provides continuous work equipment. It is necessary to ensure that it does not overheat and does not fail, turn it off in time.
• Auto mode. With it, the flow sensor regulates the work. As soon as the faucet is turned on and water begins to flow, the pump turns on. This mode is preferable to the first mode, in which the water pump for increasing pressure is protected from running in dry mode (in the absence of water), which means it will last longer. The automatic option is more economical.

There is also a classification of pumping equipment according to the method of cooling the casing. It can be carried out using the motor impeller or using the pumped liquid:

• Cooling by shaft-mounted vanes, so-called dry rotor design. These motors are characterized by high efficiency and low noise during operation.
• Cooling by pumped liquid, so-called wet rotor. The unit with such a cooling system operates almost silently.

For the user, the size of the pump is also of no small importance, because it is often necessary to install equipment in small rooms.

The dry rotor pump boasts high efficiency

In contrast to the previous one, the wet rotor pump runs silently

The pumping station will allow you to "raise" water from the ground floor or from a well

The station itself is a surface centrifugal unit for increasing water pressure, which is connected to a hydraulic accumulator and a pressure switch that controls the entire system. With its help, water is taken from the system and supplied to the tank. Even after the pressure switch turns off the pump, the consumer can use the stored water, which is very convenient if the water is often turned off. In this case, the pressure will drop. As soon as it drops to a certain level, the relay will work again and the pump will turn on again. It is easy to guess that the larger the tank, the longer the equipment lasts, since it turns on and off less often.

The scheme of connection to the water supply in a private house

A typical connection diagram for a pressure booster pump in a private house is shown in the figure below.

Scheme of installing a pumping station in a private house with a nearby well

What to consider when choosing a specific unit for a house or apartment

So choosing pump equipment There are a few important points to keep in mind:

• the assigned task;
• characteristics (capacity and generated pressure);
• the authority of the manufacturer;
• the dimensions of the room in which the equipment is planned to be installed;
• the amount to be spent on its acquisition.

Without knowledge required performance and pressure right choice it is very difficult to do. Everything necessary calculations it is better to trust a specialist. Many companies that sell such equipment provide such a service for free.

If you just need to slightly increase the pressure in the system, by about 1.5 atmospheres, then the compact pump, which can be easily and simply inserted directly into the pipe, is ideal. Scheme (to the photo): 1 - Circulation unit; 2 - Filter; 3- Stopcock; 4 - Temperature controller; 5 - Safety valve.

Compact booster pump can be plugged directly into the pipe

Some experts consider the installation of an expensive and powerful pump redundant. In their opinion, a more rational option is several devices. less power, which are connected directly in front of the points of analysis and household appliances, the work of which must be optimized.

Video: installation and launch of a pumping station with a storage tank

Buying pumping equipment to ensure good water pressure in an apartment or house is not a problem, it is widely represented in household appliances stores, online stores, construction markets. But it’s better to go to a branded salon, where there is a wider choice, there is an opportunity to get expert advice, and there is a warranty service, which is especially important for those who purchase an expensive model.

A life modern man unthinkable without plumbing. But often the owners of both apartments and summer cottages on different reasons faced with the problem of insufficient pressure in the system. This can bring a lot of inconvenience, because household appliances - washing and dishwasher, boiler, geyser stop working at low water pressure. It happens that water may not flow to the upper floors of skyscrapers at all. In private houses this problem can occur if there is a storage tank at the heart of the system and water flows by gravity.

To solve the problem low pressure there are two ways. You can install a pumping station, but this method is not at all cheap. It will be easier and cheaper to install a boost pump.

1 Characteristics and principle of operation

Plumbing in multi-storey and private houses includes several basic structures and elements. The main one is the pipeline.

One of important parameters water supply is the pressure in the system. European water pressure standards are 4-5 atmospheres. This minimum comes from necessary requirements plumbing fixtures. For example, at pressures below 2 atmospheres washing machine won't even start. For various showers, whirlpools require a pressure of 4 atmospheres. And for hydromassage devices, even higher parameters are needed.

However, pressure above 7 atmospheres can seriously damage the water supply network. Therefore, the water pressure in the system must be within the required limits and be stable.

2 Types of pumps

Devices for increasing the pressure in the pipeline are various designs and may differ significantly from each other. By purpose and type of design, booster pumps are divided into two groups.

2.1 Circulating

circulation pumps. This is a standard booster. It promotes the circulation of water in the pipes, which is why it is called circulation. The mechanism is small and compact. It cuts into a certain part of the water supply to increase the pressure and speed of water circulation.

Initially, these devices were intended for heating and systems with hot water. In lingering heating circuits, the normal circulation of the carrier in the system is difficult. Therefore, a mechanism that increases pressure is used.

The situation is similar in conventional plumbing. Only here the device is already working, increasing the total pressure of the water.

Circulation pumps consist of a motor that rotates a rotor with an impeller. This small device injects liquid into the chamber and improves the parameters of the pipeline.

2.2 Self-priming

Self-priming booster pumping stations. This unit consists of surface pump and hydraulic accumulator. The principle of operation of a self-priming pump is self-priming, that is, it can lift water in pipes even if it is not available. Then the pump pumps a certain level of fluid into the accumulator, on which the system closes. The accumulator regulates the level of pressure in the system and maintains it at required level due to the presence check valves and air membrane.

The device is configured using a pressure switch. It is also responsible for the automation of all processes.

2.3 pros and cons of different types of booster pumps

The circulation pump has low power. This increases the pressure by 2-3 atmospheres. Devices with more powerful motors work more efficiently. They pump up to 2-3 cubic meters of water per hour.

Boost stations are more powerful. It consumes at least 2 kW, but raises water up to a distance of 12 meters.

Thus, the circulation pump eliminates the problem on separate area, and suction equipment is used to regulate the entire water supply in an apartment or private house. Self-priming devices lift liquid to a height within 12 m.

Circulation pumps are also divided according to the type of media.

1. For cold water. These are the simplest models, usually made of cheap plastic. They pump water up to 40 degrees.
2. For hot water. This variety is used in the heating and hot water supply system. Made from of stainless steel and quality tires.

There are also universal devices that work with liquids of various temperatures.

According to the type of control, the pumps that increase the pressure of water in the system are divided into:

1. Devices with manual control. The device is either on or off all the time. Just make sure there is fluid in the system. Running "dry" pump can burn out. Therefore, it is turned on to perform one-time actions and turned off after work is completed.
2. Devices with automatic control. They are equipped with a special sensor that turns on the device if necessary. When there is no water in the system, the sensor turns off the device.

The cooling system protects the mechanism from overheating. It can be of two types.

1. With a "wet rotor" devices are cooled by water flowing through the pump. Their operation is almost silent, but they can overheat when working without water.
2. Devices with a "dry rotor" are cooled by rotating blades that are mounted on a shaft. They have a higher level of performance, but are also quite noisy during operation.

Pumps are also divided according to the installation method into:

• horizontal;
• vertical;
• universal.

They differ in the presence of speeds:

• single-stage - one pumping speed;
• multistage - work of different intensity, depending on the flow of water.

Construction type:

• in-line - these are compact models, inefficient. Embedded in the pipeline;
• vortex - high performance, but noisy in operation and require special piping.

2.4 How it works

The booster pumps work as follows. When the fluid flow reaches 1.5 cubic meters, the position of the motion sensor petal changes. The pump will then turn on automatically. When fluid flow is stopped, the pump turns off.

Sometimes it is necessary to install two or more step-up devices. This need arises in cases with improperly designed plumbing system. The cost of additional equipment and pipeline modifications should be calculated. And choose a more economical option.

3 Device selection

When choosing a pressure booster, the characteristics of the equipment, calculations, required tasks, the manufacturer's company, as well as the amount for its purchase are taken into account.

If there is liquid in the pipeline, but its pressure is weak, you can choose a circulation model.

If there is no water in the tap at all, but there is below the level, then you should choose a booster station with a self-priming pump.

For plumbing in a private house, built-in pumps with a wet rotor are usually chosen. This option is easy to install and silent in operation.

Devices with multi-stage adjustment and a stainless steel case are more preferable, but also more expensive.

3.1 What parameters do you pay attention to when choosing?

When choosing a pump responsible for increasing the pressure in the water supply, its parameters are also taken into account.

1. Power. Must match the needs of the system. The number of taps, characteristics of household appliances are taken into account. Too much power can be harmful.
2. lift height. A self-priming apparatus designed for smaller loads will not raise water to a sufficient height.
3. Pipe section size. If the device and pipe different section, then the pump will work with overloads and the pressure will be less than expected.
4. Noise level.
5. Apparatus size.

4 Reverse osmosis systems

There are methods for water purification:

• mechanical;
• reagent;
• chemical.

But it is becoming more and more popular these days. reverse osmosis water purification. It is based on the membrane method, in which water is purified from impurities.

4.1 When is a pump needed?

Pumps for reverse osmosis systems are used if the pressure in the pipeline is below 2.8 atmospheres, which is necessary for the operation of the installation. If the pressure is below the required value, the unit will shut down.

The reverse osmosis scheme with a pump differs from the usual one only in the presence of a pump. The reverse osmosis pump is equipped with high and low pressure sensors that turn off the device if necessary. The device also has dry run protection. If the liquid storage tank is full, then the sensor turns off the pump, and when the water starts to be consumed, it turns on the pump again. The operating voltage of the pump is 24 V and 36 V. The voltage transformer converts the mains voltage into a working pump. Transformer models differ in different types pump The reverse osmosis circuit with a pump allows you to receive clean water around the clock.

5 Hardware installation

Installation of the device for increasing the water pressure is performed as follows.

1. Mark the pipe on which the pump will be installed, taking into account the length of the device and adapters.
2. The water is turned off in the room.
3. The pipe is cut in the marked places.
4. Threads are made on the cut ends of the pipe.
5. Adapters with internal threads are screwed onto the pipes.
6. Fittings that are included in the kit are screwed into the adapters. When installing the device, follow the instructions of the arrow on the body of the device, which indicates the direction of water flow.
7. A three-core cable is pulled from the electrical panel to the device. It is advisable to equip a socket near the device, connect the device through a separate RCD.
8. Turn on the pump and check its operation. Check for leaks from fittings. Tighten fasteners if necessary. For effective sealing, FUM tape is used, which is wound around the thread.

5.1 GPD 15-9A BOOSTER PUMP INSTALLATION (VIDEO)

The presence of running water in the house means maintaining a constant pressure and pressure of water. However, the parameters do not always meet the demand, and in such cases it is necessary to install a pump to increase the water pressure. The equipment must be installed, otherwise all household appliances will not cope and will fail. When choosing a booster pump or water supply stations, be sure to correctly calculate the parameters and familiarize yourself with all types of equipment.

For the unit of measurement of pressure in the water supply pipeline, the following values ​​\u200b\u200bare used: 1 bar \u003d 1.0197 atm. = 10.19 m of water column. The standards recommend a level of no more than 4 atm, but the differences are quite significant. In particular, the pressure in the house is more than 7 atm. destroys equipment, but the figure is less than 2 atm. so small that neither the washing machine nor the dishwasher will work. Minimum pressure for the flawless functionality of all devices 2.5-3 atm. When descending, a booster pump will be required to maintain the pressure level at the desired height.

To select equipment, you will have to specify the problem:

• Low tap water pressure;
• The upper floors are not provided with water flow at all.

In the first option, a pump is suitable for increasing the water pressure in the house, and in the second, you will have to use the services of a water station.

Model range classification

The calculation will tell you whether you need to add pressure to the water or whether you have to raise the aquifer to the top floor in the house. If only an increase in pressure is enough, medium-sized equipment installed in an autonomous or public water supply pipeline is quite suitable. To supply water to the top, you will need an automatic high-pressure centrifugal water pump with a hydraulic accumulator. Such devices are equipped with manual mode and automatic:

• manual mode will ensure continuous operation of the unit. But you need to make sure that such a pump for increasing water pressure is not subjected to overheating, otherwise it will fail. Therefore, it will have to be turned off from time to time;
• automatic pump controlled by flow sensor. When the tap is turned on, the pump starts up. Advantage: protection against dry running, which means that the unit will work much longer. Profitability is due to the inclusion of the pump only when the tap is opened, which is also a plus for increasing the service life.

According to the method of cooling the unit, the models also differ:

• dry rotor - a design cooled by the movements of the impeller blades. This type of booster pump has a high efficiency, low noise, which is very important when working in the water supply system in the house;
• wet rotor - a unit cooled by flows of pumped water. This is an almost silent device, the compact dimensions of which allow you to mount a pump that increases pressure in any pipes.

Important! When choosing pumps to increase the pressure in the water supply, it is worth reading the appointment: universal, for cold or hot water!

Pumping stations: differences and characteristics

If necessary, the delivery of liquid to the upper floors the best unit there will be a self-priming pumping station. The device is able to cope with problems that are beyond the power of pumps in both a private and multi-storey building. You can mount the device with or without a hydraulic accumulator, professionals advise not to neglect the storage tank, especially when it comes to the last floors in a high-rise building.

Household stations are a centrifugal pump that increases pressure surface type connected to a hydraulic accumulator and equipped with a pressure switch. With the help of the unit, water is taken from the system and supplied to the storage tank. Even after turning off the device, the user will be able to receive water from the tank, and the pressure will be the most comfortable.

What to consider when choosing a unit?

When choosing a device, you need to consider the following points:

1. the problem to be solved by the pump or station;
2. characteristics of the device (created pressure and throughput);
3. model and manufacturer;
4. the size of the room where the equipment will have to be placed;
5. price.

Of course, not every user can independently calculate the performance and the required pressure. Therefore, it is better to call for help from a specialist or contact the company where the equipment is manufactured: often representatives, selling stations and pumps, provide installation services for free. If you need a slight increase in pressure, choose a compact pump that cuts directly into the pipe - it will ideally cope with an increase in pressure of 1-1.5 atmospheres and does not take up much space.

Attention! Professionals often suggest that installing several low-power appliances more profitable installation equipment of the required power parameter and quite expensive. This makes sense if you put structures to increase the pressure in the water supply directly in front of the points of analysis.

For the smooth functioning of plumbing fixtures, it is necessary that the water pressure in the water supply system correspond to a certain indicator, which is usually calculated individually.

But correct calculations do not guarantee that in practice the water pressure will be optimal. Owners country houses most often faced with the problem of low water pressure in the pipes. It can be solved by introducing equipment.

We propose to figure out what are the pressure standards in the water supply of a private house and for what reasons the pressure decreases. We will offer effective methods improving the efficiency of water supply. We added material detailed photos instructions and videos.

Residents of private houses are forced to calculate the pressure in the water supply individually. If the system is autonomous, the pressure may exceed the allowable regulatory documents borders. It can fluctuate around 2.5-7.5 bar, and sometimes reach 10 bar.

Standard values ​​for normal operation systems with an interval of 1.4 - 2.8 bar, corresponding to the factory setting of the pressure switch indicators.

If excessively high pressure is provided in the system, then some sensitive devices may fail or work incorrectly. Therefore, the pressure in the pipeline must not exceed 6.5 bar.

High pressure in the water supply can cause the pipe to leak, so it is important to pre-calculate optimal level head on your own

Gushing artesian wells capable of delivering up to 10 bar. Only welded joints can withstand such pressure, while most fittings and shut-off and control units are destroyed under its action, resulting in leaks in the areas.

It is necessary to determine what water pressure is necessary for the normal functioning of the water supply system of a country house, taking into account the household appliances used. Some species plumbing devices do not work at low pressure.

For example, for a jacuzzi, a pressure of 4 bar is required, for a shower, fire extinguishing systems - 1.5 bar, for washing machine- 2 bars. If you provide for the possibility of watering the lawn, then there should be a strong pressure of 4, sometimes 6 bar.

Household plumbing fixtures connected to the water supply are able to work correctly only from a certain pressure, which is usually at least 1.5 bar

The optimal pressure indicator for a country house is 4 bar. This pressure is enough for the proper operation of all plumbing devices. At the same time, most fittings, shut-off and control valves are able to withstand it.

Not every system can provide a pressure of 4 bar. Typically, for country houses, the pressure in the water supply is 1-1.5 bar, which corresponds to gravity.

Causes of low pressure in water supply

V country houses water in the water supply network comes from or.

If the system is completely autonomous, then two points must be taken into account to create the desired pressure:

• the need to ensure the rise of water;
• it is important to make a correct hydraulic calculation and implement it correctly in practice - to ensure the necessary pressure at points remote from the catchment area and at points located at different heights.

Two main problems of individual water pipes follow from this:

1. Not enough well resources- the flow rate of the hole does not allow maintaining normal pressure, and, consequently, increasing the pressure.
2. Plenty of water in the well, so the pumps can pump high pressure (up to 6 bar), which can lead to broken connections, leaks, and rapid equipment wear.

In the first case, pumps pump liquid, creating its circulation until a certain pressure arises, but over time it weakens. In the second case, you need to choose a pump with a capacity that is equal to the daily rate of water consumption.

The flow rate of the well directly affects the pressure of water in the pipeline and its volume supplied for one pumping

However, most owners of private houses are concerned about the question of how to competently increase the pressure in their own water supply, and not lower it, because only some artesian wells have the necessary flow rate to create high pressure.

Most of the holes generate little or no water pressure at all.

If standard household appliances are used in the house, then it is enough to raise the pressure to 2.3-2.5 bar - this wave is enough for their uninterrupted simultaneous functioning with good pressure. If a jacuzzi or irrigation system is provided, then higher pressure is needed.

A manometer is used to measure pressure. It is bought separately and built in at the point of entry of water into the house. A water meter is also installed there. Some equipment comes with a pressure gauge. For example, a heating boiler, if a FGP is provided.

The principle of adjusting the pressure of the water supply networks of private houses is the same as autonomous system, the network differs only in size

A simple pressure gauge has a scale from 0 to 7, which allows you to install it in an apartment, a private house.

Methods for pressurizing the system

If the pressure in the water supply is low, then the reason may be as follows:

1. There is water in the pipeline, but there is no pressure.
2. There is no water in the pipeline on the upper floors.

To solve the first problem, it is necessary to introduce a pressure booster into the system; to solve the second, install a storage station.

Before implementing technical means into the water supply system, you should first check the network for clogging:

#1: Introducing a booster pump

If there is water in the pipeline, but there is no pressure, then install pressure pump. Also, the device can be implemented if there is no pressure in an apartment with central heating.

The reason for the lack of pressure may be the following:

• the well is located remotely at home;
• the power of the base pump is not enough to supply water to the upper floors.

The pump is usually mounted at the entrance to the domestic pipeline network in front of the manifold or the first tee.

There is one drawback of central pumps - they create a vacuum, that is, they can pump saturated with air water. Conventional pressure centrifugal pump sensitive to the air content in the liquid, so you should give preference to vibration modifications.

The water pump is powered by an electric motor. The inner element rotates, thereby increasing the pressure in the pipes. The body of the device is usually made of durable plastic.

To install the device in an apartment building, it is important to choose a modification of the correct power, otherwise the owner of the “pumped” water supply will lower the pressure in neighboring apartments. It is recommended to put the pump on a pipe leading to a specific household appliance.

In the general case, the pump is cut into a common pipe, which is responsible for supplying water to an apartment or house. The device itself is quite compact and inexpensive.

#2: The main types of pressure pumps

There are models with a dry and wet rotor (flow-through). The wet rotor pump elements are lubricated by the passing fluid. Devices of this class do not require additional maintenance if they are initially connected correctly.

An electric pump, unlike a vibration one, is installed between the water supply and the water source

A pump with a dry rotor has good power, but it needs regular maintenance, it produces soft sounds during operation, reminiscent of a mosquito squeak. Its parts are protected by a waterproof damper, so you will have to clean the device once a month.

According to the type of operation, pumps are divided into the following types:

• manual booster pump and with manual control. The model constantly works, has no automatic switches. The device has a simple design that is understandable to ordinary people; most often the device is used in "warm floor" systems;
• automatic pump- starts only when you turn on the tap or household appliances. After they are closed, it turns off.

An automatic pump is more expensive than a manual one, consumes little energy, quickly responds to changes in pressure and is the most popular today.

Choosing a pressure pump is quite simple.

It is important to determine the following:

• for hot or cold water the device will be installed;
• the required level of pressure - the higher the indicator, the greater the pressure in the system.

Accordingly, the higher the pressure, the more power is needed and bandwidth equipment.

It is equally important to choose a pressure pump taking into account the brand, since in the event of a breakdown, not every repair service will undertake to put in order the production model of an unknown company. The most famous and recognized manufacturers - Grundfos, Wilo, Sprut. Each company specializes in the production of different modifications of the device.

The Wilo PB-401SEA pump is designed to increase the pressure in water supply networks housing. Can be installed in both suction and delivery sections

For instance, Grundfos produces circulation pumps of small volume, Wilo develop models with a built-in hydraulic accumulator.

To connect the circulation pressure pump you need:

1. Turn off the water in the area.
2. Release water from the pipeline and the system as a whole.
3. Cut off the part of the pipe in which the installation will be carried out.
4. Attach fittings and nozzles to the joints.
5. Insert the equipment into the plumbing.

It is also acceptable to use polypropylene or rubber hose to simplify installation. In modern circulation pumps these pipes are included.

#3: Pressurizing the storage tank

When the pipelines in the house are without water, or if there is water on the lower floor, but does not reach the upper ones, it is necessary to purchase a storage pumping station. It is also introduced into the system when the network pressure is less than 0.2 bar and the flow rate is less than 2 l/m.

Any pumping station works on the same principle. Mount it at the junction point of the external or internal branch of the home pipeline network

The principle of its work is the following. The pump pumps liquid into the station (tank or accumulator), which operates at a pressure of 1.5-2 bar. Water enters until a pressure of 1.5 or 2 bar appears in the tank. If the station is equipped generated pressure may be an order of magnitude higher.

After generating the required pressure, the pumping station switches off automatically.

into construction storage station special pressure sensors are introduced. When the pressure drops to 1.5 bar, the main pump turns on, when it rises to a certain level, it turns off.

The system with a pump and a storage tank has many nodes, which makes it difficult to self-assembly. In order for the equipment to work correctly and smoothly, it is better to contact specialists (+)

The pump in the station can be one of two types - or vibration.

According to the type of absorption, there are:

• detachable ejector designs– capable of generating a pressure of 5 bar. The ejector is immersed in the well, and the tank itself can be located at home, since it practically does not make noise during operation. The station is mainly used in cases where the water source is located deep, and its disadvantage is sensitivity to mechanical elements - sand, dirt, etc.
• equipment with built-in ejector– suitable for shallow (up to 8 meters) wells and wells, works effectively in dirty water, is not sensitive to air ingress, but differs high level noise, so it is usually installed in special outbuildings.

Models with a storage tank are economical (the start occurs when the tank is empty), but they have many disadvantages: they generate low pressure, have large dimensions, there is a possibility of a rupture, as a result of which the room may flood.

Stations with a storage tank are practically not used today. They were replaced by models with a hydraulic accumulator. They possess small size, do not make noise during operation.

You can install the device in the basement, utility room, separate extension. This minimizes the risk of leaks. But the accumulator has a small capacity reserve (about 25 liters) and is not used for wells with a low flow rate.

Pumping stations are often used in complex, branched and long water pipelines as booster equipment that pumps water from storage tank at the water points

Stations are also divided into surface (when the pump is located on the ground) and submersible (the device is immersed in water), the latter are conditionally divided into well and borehole.

To increase the level of water pressure in the apartment pipeline, pumping stations are not used due to design features and noise during operation.

Despite its impressive cost, the pumping station has a number of undeniable advantages:

• it is possible to set any desired pressure in the house, which will allow the use of any plumbing fixtures, including those that require high pressure to function;
• the water supply will be uninterrupted even if it is absent in the central line (due to the presence of a storage tank).

The system has disadvantages - it is bulky, takes up a lot of space.

It is important to correctly determine the volume storage capacity. This value is taken taking into account the average daily rate of water consumption. If the family consists of 3-4 people, then about 500 liters of water will be enough per day.

When calculating, it is also important to take into account that the water needs to be renewed from time to time in order to avoid the appearance of bacteria.

If there is enough water in the tank (or the pressure in the system drops), then the pump automatically starts, which builds up the necessary pressure in the network, and after reaching a certain point it turns off

It is important to clean the storage tank in a timely and regular manner, since pathogenic bacteria accumulate in it. Small bags of technical silver placed inside the tank prevent their reproduction.

It should be remembered that the overflow pipe should not have stop valves. If the float valve fails, then water will be drained through it.

It is also necessary to install a bypass so that in the event of a breakdown of the station it is possible to turn off the system without completely turning off the water supply.

As you can see, it is not difficult to raise the pressure in the water supply. To solve the problem, a pressure pump or a special pumping station is used. If it is possible to carry out the installation of the pump on your own, then the installation of the station should be entrusted to professionals.
