Pump to the apartment to increase the flow of water. Pump to increase water pressure: a solution to the problem of low pressure. Pumping station: principle of operation

You need to purchase a pump to increase water pressure if you know the reason for the low pressure. First, figure out what caused the low fluid pressure in the system. Not all pumps are suitable for the formation of a higher pressure, we will tell you how to choose the right unit!

Causes of weak water pressure

A pressure gauge connected to the water supply will help measure the pressure force - it is advisable to take measurements more than once, but observe the readings of the device for at least two days, taking measurements during peak water consumption hours (usually morning and evening), and also test the pressure day and night, and not in one part of the system.

It is optimal to take measurements in neighboring apartments on the same floor with you and “vertically” in order to get a complete picture ().

If the pressure gauge gives different values in different areas, most likely we have clogged pipes. Old steel pipes could, over the years of operation, “overgrow” with a bloom and become clogged with dirt - they will have to be replaced.
Clogging of the sump, usually located in front of the water meter, can be determined by equally reduced pressure indicators in the water supply segments located after it. The sump must be opened and thoroughly cleaned.
If the pressure gauge readings in different segments are normal, but the trickle is barely flowing, it may be in the aerator (a strainer built into the faucet gander). Unscrew the crane, unscrew the mesh from it, clean it and return it to its place.

If everything is in order with the pipeline, sump and aerator, and the pressure is still low, get it checked in the house manifold. If it is below the norm there, it means that the service provider is not fulfilling its obligations. But it is often no easier to get problems solved from public utilities than to wait for an increase in the standard of living in the country, so consumers make do with their own methods.

Booster pumps designed for cold water supply help to save the situation: it is worth installing one to increase and stabilize the pressure force.

We select a pump for an apartment

Choose a water pump installed in an apartment by counting how many taps and devices you have connected to the water supply. Traditionally, built-in pumps are chosen for residential use. Check if the pipe cross-section and model configuration match (there are some created for specific cross-sections).

The higher the power of the unit, the higher the number of consumers and devices served by it. "will serve". It is also important how much noise it makes: the "trumpet of Jericho" is clearly not the best option. A pump in a small apartment is better to choose a more compact one.

Choosing a pump for a country house

What kind of pumps to increase water pressure are used in a private house? As a rule, they acquire wet-rotor in-line ones. They produce little noise and are easy to install. Having determined the place for installation, choose a unit mounted vertically or horizontally. Devices "packed" in a stainless steel case are more expensive than cast iron ones.

Principles for selecting booster pumps

When evaluating high pressure water pumps, design features are usually taken into account:

Units with a wet rotor are in-line (they are cut into a water supply segment in front of a draw-off point or a device that needs a pressure of a certain force). They do not require prevention - they are "self-lubricated" by what they pump. They are compact and quiet. But their productivity is relatively small, and one nuance must be taken into account during installation: the rotor axis of the electric drive of such a pump must be located strictly horizontally;
Dry rotor units are distinguished by a removed power unit with its own cooling device - a fan, so they need to be additionally fixed to the walls. Such a unit is more productive than a wet-rotor one, and has the ability to serve more than a single water point. But he needs prevention - friction units need lubrication. When working, it makes a little noise.

Conclusion + related video

So, the pump model you have chosen will help bring the pressure indicators in the water supply system to the standard values (there is a choice).

If the area of \u200b\u200bthe place of residence allows, a pumping station to increase water pressure would be a good solution - thanks to a hydraulic accumulator, it is able not only to raise the level of pressure, but also to create it “on its own”.

The main characteristic of the normal functioning of water in the system is the presence of optimal pressure. However, it is not always possible to maintain good pressure, especially when there are various devices connected to the water supply system. There are several ways by which you can increase the water pressure. We will learn about their features and technology of execution further.

Water pressure in the water supply: the optimal value and reasons for the decrease

In order to determine the method of increasing the water in the water supply system, you should first find out the reason for the decrease in water pressure. Most often, the reasons for the decrease in water are:

the presence of leaks or accidents at the place of water transportation;
the presence of foreign deposits inside the pipes that interfere with the normal circulation of the liquid;
the presence of a faulty filter that purifies water;
valve problems.

If there is a centralized water supply in the house, the water pressure often decreases due to poor-quality work of the water transporter. For example, in order to save electricity, one or more pumps are turned off, which improve the pressure. In the presence of damage to pipes in certain sections of the pipeline, the water pressure also decreases.

Therefore, if you have a sharp drop in water pressure in the system, first of all ask your neighbors, they did not have such problems either. If the pressure has decreased not only in your area, then contact the water supplier in your area directly. The minimum water pressure in a one-story building should be one bar. This information is recorded in legal documentation and must be followed by all utilities.

Between the water supply system that comes to the house, install a pressure gauge with which you can control the water pressure in the system.

If the problem of reducing the water in the system affected only you, then you need to check the pumping station for its performance. Most often, the deep filter, which purifies the water before introducing it to the house, is clogged.

In addition, you should inspect the filters that provide fine cleaning, they connect household appliances to the water supply. Problems with these types of filters lead to improper operation of washing machines, boilers, pumps, etc.

If the filters are working properly, go around the house and check the pressure in various parts of the water supply. It is possible that there is a leak inside the circuit. To determine this section, it is necessary to measure the pressure in different sections of the water supply and determine the lowest value. After the leak is repaired, the pressure should increase.

Pump that increases the pressure in the water supply: features of choice and installation

The artificial methods of increasing pressure include, first of all, the installation of a pump. Individual pumping equipment is selected for each pressurized water supply system, the choice of which takes into account factors such as:

duration of the main system;
diameter of pipes of the water supply system;
number of floors in the house;
the amount of water consumed.

When choosing water pressure pumps, pay attention to their performance and power. These indicators are the main ones when buying this equipment. In addition, the pump must be made of high-strength materials that are not prone to corrosion.

There is an option to purchase a booster pump. These models are not recommended for installation in private homes with additional equipment that consumes water.

The cost of a pump to increase the water in the system depends on the throughput of the device. The approximate price of equipment is from 40 to 200 $. Some equipment is equipped with additional automated mechanisms, such as a flow sensor. With it, it is possible to automatically turn on the equipment when the taps are opened.

Thus, the level of energy consumption in the system is reduced. The cost of equipment is also determined by the degree of its protection from moisture and additional components that are present in the water. Pay attention to models with a high-quality filtration system. Aluminum, cast iron or stainless steel is used for the manufacture of the body part of the device.

We recommend purchasing equipment in a company store of one or another manufacturer. Buying goods directly, you will not only save money, but also receive a free warranty and additional maintenance of the device.

Also, when choosing equipment for increasing water pressure, pay attention to the difference in models according to the control method:

devices with manual operation mode ensure constant operation of the device throughout the entire time, you need to monitor the device on and off by yourself;
automatic pumping devices - the flow sensor of such a device regulates the on and off of the device, there is also protection against switching on in dry mode, the duration of operation of such a device is higher than that of a manual pump, it also has an economical power consumption, but it has a higher cost.

In relation to the type of cooling of the casing part of the pumping equipment, there are two types of pumps:

when choosing a pump with cooling using shaft blades, the sounds that are produced during the operation of the equipment are quite quiet, while the efficiency of the mechanism is at a high level;
when the pump is cooled with liquid, complete noiselessness of operation is ensured.

An important role when choosing a pump should be given to its size. If the room is small in size, then the installation of a huge device will be inappropriate. Some pumps are used only for hot and cold water. Other devices are suitable for any type of water supply.

In general, when choosing equipment, decide on its following characteristics:

the purpose of the purchase of the pump;
the principle of operation of the equipment;
equipment characteristics, most often indicated in the instructions;
device size;
purchase amount;
availability of additional functions.

The main characteristics are the performance and pressure that the pump is able to create in the system. They determine the type of equipment purchased.

How to increase water pressure in a private house

The water pressure in the water supply system is determined by the number of household appliances using water. For example, if the house has a washing machine, a sink and a bathtub, then a pressure of two atmospheres is enough. However, if there is a swimming pool or a luxurious jacuzzi in the house, this value should be doubled.

In addition, the pressure in the system must be such as to supply water to several points of water intake at once. When showering and doing laundry, you should not experience the discomfort associated with a decrease in pressure.

If the site has a private water supply, that is, water is supplied from a well or from a well, then the pump power should be much higher than when water is supplied from a centralized water supply.

The performance of the pump should ensure that water is lifted from the well and delivered to the house. At the same time, the house must be provided with optimal water pressure in the system. These indicators directly depend on the amount of fluid consumed. The more water is consumed in the house, the higher the pump performance should be.

During the operation of a private water supply system, there are two options for water consumption:

1. The well is distinguished by the presence of a flow rate in which there is a weak pressure or it is completely absent. At the same time, it is possible to satisfy the water needs of two or three people in the family. Since the source is quickly emptied, there is a decrease in pressure. For these purposes, additional means of modernization are used.

2. The flow rate of the well exceeds the level of water consumption per average family. In the presence of a pump, the performance of which restrains the pressure, there is an excessive increase in pressure to six atmospheres. Thus, leaks and emergencies are formed.

When choosing pumping equipment for private wells, it is necessary to be guided by the well flow rate and water flow. We recommend choosing as a guide the daily water consumption in the summer.

Ways to increase the water pressure in the house

As methods that increase the pressure in the water supply, we single out the installation of two devices:

1. Tapping into the water supply under pump pressure - this operation is performed at the entrance of the general water supply to the house or apartment. Installing pumps in front of the points of water analysis significantly increases the pressure in the system. Compact pumps allow automatic or manual control of their operation. However, this method allows you to increase the pressure by a small amount of 1-1.5 atm.

2. To eliminate more serious pressure problems, as well as to organize a temporary independent water supply, it is recommended to install a pumping station. In this case, a storage tank is installed, in which water is accumulated in advance and fed into the system using pumping equipment.

A pumping station that has a hydraulic accumulator requires considerable investment, in addition, a lot of space must be prepared for its location. You will also need to spend money on the purchase of a storage tank, the size of which should be ten times the daily water consumption. However, in this case, you get a constant ideal pressure and water supply, even with occasional water cuts.

Stabilization of water supply pressure in a private house

Among the main ways to increase the pressure in the system, the installation of a pumping station or pump is distinguished. The first option is relevant if there is practically no pressure in the system.

The pumping station allows you to significantly increase the pressure in the system. An electric piston engine pumps air out of a water accumulator. Water from a well or water supply enters the formed vacuum space. Installation of such a station in a multi-storey building allows you to get a constant quality pressure. However, such stations are quite bulky and for their installation it is necessary to obtain special documents for permission to perform work.

If there is a minimum water pressure in the system, it is enough to install a conventional pump in the apartment. It is installed on a pipe that enters the interior of the apartment. Automatic equipment starts working when the water is turned on, while manual models mean that the pump is constantly turned on and off.

To connect the pump to the system, you will need a soldering iron, which is designed to connect pipes to each other. On the inlet pipe, the tap for supplying water to a certain apartment is blocked. Next, the pipe and the flow sensor are inserted. At the ends of the cut pipes, connecting fittings are installed, on which the pump is screwed together with the sensor. Plug in the pump and turn on the faucet.

Another option for increasing pressure is to install a pump directly in front of the water supply device. To do this, first of all, you should study the technical parameters of the device, while determining the maximum pressure for its operation.

Next, you need to purchase a centrifugal-type pump, the performance of which is comparable to the maximum pressure. Please note that centrifugal pumps are very similar to pumping equipment installed for the circulation of heat carrier in heating systems. However, the principle of operation and performance are different.

In addition to the pump, you should purchase devices in the form of a ball valve and flexible wiring. Please note that the diameter of the hose must match the thread of the pumping equipment. You will also need a fum tape, with its help it is possible to seal the joints.

Work should begin by shutting off the tap for supplying water to an apartment or house. Next, the place of installation of the pump is determined, most often it is fixed on the wall using plastic dowels. In any case, before starting the installation of equipment, read its instructions.

On the wall, mark the fixing points of the pump and install it. A flow sensor is put on the pump, which controls the process of turning the device on and off. Next, threaded connections are mounted, do not forget to install rubber gaskets. They come with equipment. The inlet on the pump is connected to the water pipe.

After assembling the device, check its performance. Install the pump and turn on the water, if there are smudges, seal the connections with fum tape. Don't forget to ground the device. Check the operation of the device in automatic mode. Look at the pressure gauge to see what pressure is present in the water supply. The optimum pressure is 2-3 atmospheres.

The situation when the weak pressure of the liquid in the water supply does not make it possible to use the washing machine and dishwasher and take a shower is faced by many of those who live in apartment buildings. One of the most popular and most affordable ways to solve this problem is to install a pump in the water supply system of the apartment to increase the water pressure. Nevertheless, such a measure does not always solve the problem completely, and in some cases it does not solve it at all. In order not to find yourself in a situation where a pump to increase the water pressure in an apartment turns out to be a useless acquisition, to solve the problem with a weak water pressure, you should use not a superficial, but a deeper systematic approach.

What can cause low water pressure in the apartment

Before finding out why the pressure in the water supply system has decreased, you should understand in what units it is measured and what value of this parameter is considered normal for domestic water supply systems.

In information tables, as well as on the scales of control devices, the value of liquid pressure can be expressed in four basic units of measurement: bar, technical atmosphere (at), meter of water column (m water column), kilo- and megapascals (kPa and MPa). When measuring pressure in domestic water systems, where too much accuracy of the parameters is not required, the following relationships between different units of measurement can be used:

1 bar \u003d 1 atm \u003d 10 m of water. Art. = 100 kPa = 0.1 MPa

What is the normal water pressure in the water supply of the apartment? According to current standards, the value of this parameter should be about four bar. This water pressure is quite enough to ensure that all plumbing fixtures and household appliances connected to the water supply system (taps, drains, showers, washing machines and dishwashers, etc.) can work without interruption in the apartment. However, this regulatory requirement is strictly observed in very rare cases. Usually, in the water pipes of apartment buildings, constant pressure surges are observed, which can occur both in the direction of its increase and decrease.

If the issue of increased pressure in the domestic water supply is solved quite simply (by installing a water reducer at the inlet to the system that equalizes the water pressure in the entire internal piping), then in order to eliminate the problem with a decrease in pressure, it is necessary to determine why this happens.

In order to find out where the pressure drop occurs - in the water supply system of only your apartment, in the whole house or in apartments that receive water from one riser, you need to interview neighbors living in the upper, lower and side apartments. If it turns out that your neighbors also need an increase in water pressure, you should contact the utility service serving your home with this issue. If this problem is local and occurs only in your apartment, then you personally should look for ways to solve it.

First of all, it is necessary to localize the section of the apartment water supply, which needs to increase the water pressure. To solve this problem, a conventional pressure gauge is used, with which the water pressure is measured at various points in the water supply system. The data obtained as a result of measurements will allow us to draw conclusions about the negative factor, the impact of which leads to a weak pressure of water flowing from the taps in your apartment.

Clogged pipes help to identify different pressure values in individual sections of the apartment's water supply system. Most often, this situation occurs when using old steel pipes, the inner walls of which are highly rough. The only way to effectively solve this problem is to replace old pipes with new ones.
It is also possible that the sump (coarse filter) is clogged, which is usually installed in front of water meters. If the reason for the poor water pressure lies precisely in this filter, in all sections of the water supply system located after such a device, the same low pressure will be recorded. The problem of clogging the coarse filter is solved quite simply: it is opened and the accumulated debris is cleaned out of it.
The least critical and easiest to solve problem, which caused a weak water pressure, is clogging of the aerator - the filter mesh that the ganders of the cranes are equipped with. A manometer will also help determine that this is the reason, which in such cases will show that the fluid pressure in all parts of the water supply is normal, but only a weak stream flows out of the tap. To fix the problem, the filter mesh is unscrewed from the gander of the crane, thoroughly cleaned and installed back.

If the water pipes in your apartment, the filter and aerators are not clogged, and the water initially enters the water supply under low pressure from the central riser, then you can install a household boost pump in the apartment to increase the pressure.

In many cases, installing a compact pump for pumping water from the central water supply system leads to an increase in pressure in the water pipes of the apartment to the standard values.

Varieties and design features of household pumps

Pumps for increasing the water pressure in the apartment according to the design can be divided into two large groups:

devices with a "wet" rotor;
water pumps with a "dry" rotor.

Pumps for increasing water pressure, belonging to the class of devices with a "wet" rotor, are compact in size, less noisy during operation and do not require special maintenance, since the lubrication of their internal parts is provided by the liquid they pump. The scheme for connecting such devices to the water supply is quite simple: they simply cut into the pipe and work like a flow pump. Such booster pumps are installed right in front of the tapping point or in front of household appliances, into which water must flow under a certain pressure.

Wet rotor pump design

If we talk about the shortcomings of booster pumps of this type, then this should include:

low productivity;
not too high rates of additionally created water pressure;
the possibility of installation only in such a way that the axis of the rotor of the electric drive of the pump is located in a horizontal plane.

Water pumps for home plumbing, belonging to the class of devices with a "dry" rotor, have higher power and performance when compared with models with a "wet" rotor. Such a booster pump, with the right choice and installation, can be used to simultaneously serve several water intake points. The power unit of this type of electric pump-pump is moved away from the main body of the device and is equipped with its own air cooling system. Because of this, the booster pump with a "dry" rotor must additionally be cantilevered to the wall surface.

Pump device with a "dry" rotor

A dry rotor booster pump requires regular lubrication of internal components subject to friction. In addition, this high-pressure water pump creates a noticeable noise during operation, which must be taken into account when choosing a place for its installation.

Starting the booster pump for the water supply should only occur at those moments when the pressure of the liquid decreases. This requirement is met by pump control systems that can operate in manual or automatic mode.

The water pressure booster pump, equipped with a manual control system, is switched on by the user when the need arises. Accordingly, the user of such a device is responsible for the serviceability of the pump for increasing the water pressure in those cases, for example, when it will run dry, without water.

The automatic pressure pump, which is controlled by a water flow sensor, turns on automatically when liquid appears in the pipeline, and turns itself off when the pipeline is empty. Equipping the pump with such an automatic sensor makes it possible to prevent equipment from idling, which inevitably leads to overheating of the device and, accordingly, to its rapid breakdown. When choosing a pump that increases pressure, you can immediately purchase a model equipped with a water flow sensor, or purchase such a sensor separately if it is not provided in the factory configuration of the pumping device. If the flow sensor is purchased separately, it should be placed after the pump that increases the water pressure.

For installation in domestic water supply systems, in which the liquid pressure can periodically be both normal and reduced, it is better to use an automatic booster pump, additionally equipped with a water pressure sensor. The task of such a device, which also operates in automatic mode, is to turn on the pressure pump in cases where the water pressure drops below normal, and turn it off if the fluid pressure meets the required parameters. In this case, the pressure pump will not turn on even if it receives a control signal from the flow sensor, if the water pressure meets the required values.

In cases where the living area allows, an increase in the pressure of the liquid in the water supply system can be provided by a pumping station for the apartment. Such a pumping station, the design of which, in addition to the pump itself, is made up of a membrane-type accumulator and a pressure sensor, not only increases the pressure to the required level - it creates it itself.

The efficiency of the pumps used to increase the pressure in the water supply system is largely determined by the correct choice of such equipment.

When purchasing a booster pump for water, you need to pay attention to the following parameters.

The power of the device is a parameter that determines the number of water intake points that can be served by a pressure-increasing pump for a water supply system. When choosing a pump on this basis, you should first of all decide on how many taps and household appliances in the apartment it will have to supply water under the required pressure.
The noise level that the pump makes when it pumps water into the system should also be known before purchase.
Separate models of pumps for increasing water pressure are installed on pipelines of only a certain diameter. Otherwise, such a device will not only not contribute to an increase in water pressure, but will also start to work with overloads, which will lead to its rapid failure.
The height of the water level rise that the pump can provide is a parameter that is relevant in cases where not ordinary apartment boosters are selected, but pumping stations used to increase the water pressure in the pipelines of several consumers at once.
The performance of the device is a parameter on which the amount of liquid pumped by the pump to increase the pressure in the water supply system per unit time depends. When choosing a high-pressure pump for water, it should be borne in mind that the value of the named parameter must be higher than the average water consumption consumed by the water supply system or water intake point where such a device is planned to be installed.
It is also important to consider the maximum allowable temperature of the pumped water. The type of pipeline (cold or hot water supply) on which the pump can be installed depends on the value of this parameter.
The size of the device determines the choice of a section of the water supply for connecting the pump.
The manufacturing company, its fame and credibility in the market are no less important than all of the above parameters. When choosing high pressure water pumps, it is better to give preference to models from well-known manufacturers that produce high quality products, provide reliable guarantees for them and provide maintenance and repair.

How to ensure high water pressure throughout an apartment building

The problem of low water pressure, which worries residents of apartment buildings, can be solved in a more radical way - by installing a pumping station to increase water pressure, which will serve the entire house. Such pumping stations for supplying water to the apartments of the whole house, operating in automatic mode, are equipped with a self-priming centrifugal pump, a hydraulic accumulator and a pressure switch. Pumping stations of this type are also used in autonomous water supply systems for a private house or cottage.

Another way to increase the water pressure in the apartment pipeline is to install a storage tank in which the liquid will be accumulated and then, when the pressure in the pipeline drops, it will be returned to the system. Of course, given the small areas of typical apartments, it will be quite problematic to install such a capacity inside the housing. However, many of those who are constantly faced with problems associated not only with low water pressure in the pipeline, but also with its regular absence in it, install small storage tanks (200-500 liters) in their apartments.

A multi-pump station allows you to "remove" the effect of the upper and lower floors in terms of water supply to them

It is also possible to place a storage capacity of a much larger volume on the roof of an apartment building or in its attic part. To install such a container, the volume of which can be very impressive, it is better to cooperate with the rest of the residents of the house in order to share the upcoming financial costs with everyone who wants to use the water supplied to taps or household appliances at the required pressure at any time.

A water pressure boosting station, equipped not only with a hydraulic accumulator and elements of an automation system, but also with a large storage tank, is another way to effectively solve the issue of low fluid pressure in the water supply systems of apartment buildings. Such a pressure boosting installation will provide all apartments in the house with water, not only in cases where the liquid pressure in the central water supply system needs to be increased, but also when water does not enter the pipes at all.

Naturally, in order to purchase all the elements of equipping such a serious installation, as well as to carry out its qualified installation, the residents of an apartment building will have to agree and incur joint costs.

The benefits of any apartment buildings are efficient communication systems, which include plumbing. The operation of household appliances, such as a boiler, washing machine or dishwasher, depends on the quality of its functioning. In some situations, the installed pump helps to increase the water pressure. It pumps the required level in the system, providing a continuous powerful flow.

A booster pump will be the best solution for the local level. It is mounted within the apartment and is designed to serve one household. The installation of such equipment will become effective if the problem lies solely in the lack of pressure, but at the same time all the pipes are not clogged and the rest of the supply system is fully operational.

The need for arrangement

Pumps to increase water pressure are introduced into the home hydraulic system, often on the upper floors. There, the established norm often reaches the planned values. The optimum is an indicator reaching 5 bar. However, in reality, the value in the pipeline sometimes drops to the level of 1 bar.

Such parameters are unacceptable, since in this situation automatic washing machines that require at least 2 atm may not even start. It will be possible to take a shower in the shower cabin only at 3 atm. Approximately 2-2.5 atm is needed to start the boiler. The jacuzzi will be in working condition at 3-4 atm.

Operating parameters of connected equipment

Before connecting, you need to figure out which booster pumps for water have characteristics. The difference in them happens in the way they start:

User launch option. The hydraulic apparatus is stably turned on / off by the owner. It is enough for owners to control the presence of liquid in the system, since operation without water leads to a quick failure from overheating. Often a feature of the operation of such schemes is one-time operations with subsequent shutdown.

Models for pumping water with automation installed in the system, thanks to special sensors, are connected independently as needed.

When choosing equipment, you should pay attention to the ability to transport a stream of a certain temperature. Structural features are manifested in the possibility of passing water in a limited temperature regime. In specialized outlets or on the websites of online stores, you can find the following types of devices:

units capable of working exclusively with cold systems;
models designed to be included in hot flow wiring;
universal equipment designed to interface with any liquid temperature.

A well-functioning pump, which should not overheat significantly during operation, helps to maintain the stability of the pressure level.

Cooling systems help to get rid of overheating.

According to this type, productive models are divided into the following groups:

The temperature is lowered by the flow passing through the housing. This technique is called the "wet rotor" method. It has minimal noise parameters, but is capable of overheating when operating without water.

For cooling, rotating blades fixed on the shaft are used. The method is called "dry rotor". The disadvantage is the increased noise during operation. The disadvantages are offset by a fairly high degree of performance, which the pump for water pressure has.

Introduction of step-up stations

For owners of apartments, from the upper levels, it is advisable to install a pumping station. Self-priming equipment includes the following elements in the circuit:

hydraulic pump;
manometer;
relay;
hydraulic accumulator.

The principle of operation of the unit is to pre-fill the accumulator, set the desired outlet pressure on your own using a relay, and start the pump, which ensures the distribution of fluid to consumers.

In some schemes, it is proposed to exclude the accumulator, however, this approach will negatively affect the duration of operation of the entire pressure unit. It is advisable to choose a larger tank that will fit into the interior of an apartment or house, as this will allow you to turn on the boost system less often.

After the volume is pumped into the tank cavity, a shutdown occurs. In this case, the consumer receives a jet from the accumulator even in the situation when there is no water supply in the system at the moment. If the liquid is completely out of the tank, the relay will automatically turn on the pumping.

Before purchasing a station, it is recommended to clarify its maximum pressure. You can use the popular model Grundfos JP Booster 6-24L, which will provide a pressure of 48 m and has a considerable tank with a capacity of 24 liters. Its cost is approximately 24 thousand rubles.

How to choose the right pump to increase water pressure

When choosing the right booster pump, there are important factors to consider:

Power characteristics. The more productive the unit is, the wider the number of points that it can effectively serve. In the calculations, it is necessary to monitor the number of consumers, washers and plumbing fixtures.
Noise. Of course, less noisy devices are preferable, but they may have a higher cost.
Patency. It is important to pay attention to what diameter of water pipes the pump can be combined with. Working sections are specified in the user manual. Failure to comply with this parameter can lead to work with overloads, breakdowns and a decrease in pressure below the calculated value.

Appliance device

lift height. When buying a pumping station with a lower load, it may not reach the required level.
Equipment dimensions. The hydraulic assembly must fit neatly into the allotted space.
Reliability. It is preferable to choose proven well-known brands that have a long warranty period.

The main selection criterion is the outlet pressure indicator, which should not be less than 4 barrels. Further, they are already determined directly with the characteristics of the electrical appliance - dimensions, noise level when turned on, wet or dry, etc. Since we are talking about a high pressure pump, for many it will be a matter of principle - manual or automatic control.

Pumping equipment for hot water supply is different from that which is installed in a system with cold water.

In most cases, when choosing, preference is given to well-known brands. Having overpaid, relatively speaking, just for the brand, the user receives high-quality working equipment and warranty obligations, which the seller or the manufacturer will definitely fulfill.

Among the priority companies:

WILO- the leader in consumer demand according to reviews and store statistics. It is considered elementary in operation, has been operating for more than 7 years in extreme conditions and is very reliable in operation.

Grundfos- in some regions, even Vilo bypassed. The obvious pluses are silent operation and low weight. The factory warranty is 12 months.

OASIS- easy to operate, high-quality equipment, which is only striving for the TOP-10, but has not yet come close.

The leader of domestic production, although it does not enter the European market. All without exception are compact and low-noise. Branch pipes for installation are unified for Russian water utility systems.

Water low-pressure pumps on collectors work non-stop. In order for the pressure to increase gradually (in steps), a multi-wheel system is used. During operation, the device is able to create a pressure in the system up to 10 bar.

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.
