Circulation pump to increase the pressure in the system. Pumps for increasing water pressure in an apartment: types, design and application features. The pumping station does not gain pressure - what to do?
A pump to increase water pressure is needed when there is low pressure in the water supply networks in order to make the liquid supply stable. The water pressure booster pump is produced by many manufacturers, so the consumer is often faced with the task of choosing such a unit according to certain criteria that correspond to the specific conditions of the water supply network.
What indicators should be used to select a pump?
A pump that increases pressure, like any other technical device, has certain characteristics. The main ones are the minimum inlet pressure and the maximum value that the booster pump provides for the water supply. The standard pressure that water should have in household pipeline networks is 4 atmospheres. But in real conditions, this figure can reach 7 atmospheres, which has a very bad effect on any plumbing and pipelines.
If the water in the pipes has less than 2 atmospheres, then no device such as a washing machine or jacuzzi will work. The minimum value of this parameter for the operation of the entire water supply system is chosen within 2.3 atmospheres. Some pressure boosting pumps have values expressed in meters of water column in their data sheets. When purchasing a unit, you must take into account that one atmosphere is equal to 10 meters of water column. For systems fire safety 3 atmospheres are taken as the standard. According to all of the above, pressure booster pumps must provide output operating pressure water from 2 to 4 atmospheres with fluctuations of this parameter at the inlet from 1.5 to 2 bar.
Types of units for flow stabilization
Such a pressure boosting pump is a flow-through apparatus, the operation of which creates additional force, sharply increasing the fluid pressure at the outlet.
- There are several types of pumps that increase fluid pressure in a pipeline:
- Household pumps for creating water flow in a private house or increasing water pressure in an apartment on a high floor. A garden pump capable of lifting water from deep well
- and used for watering plants in the garden or vegetable garden.
All types of pumps have two operating modes:
- Manual control that allows you to implement the mode continuous operation. At the same time, the person himself ensures that the unit does not overheat, and, if necessary, turns it off.
- Automatic control is based on the use of a flow sensor, which turns on the pump only when the consumer's tap is opened. This mode is more economical and the equipment lasts much longer.
- The units are cooled by a fan impeller or a flow of pumped liquid.
The pumping station includes a centrifugal unit capable of increasing the flow of water so much that the module can pump it out of itself. deep well or increase the fluid flow rate so that it reaches last floor high-rise building with the required parameters.
To obtain high-pressure liquid when the flow is unstable, a hydraulic accumulator is installed in the station, increasing the pressure in the water supply. The consumer receives water from its tank when the pressure switch turns off the centrifugal pump when the supply of liquid from the central network stops.
What should a consumer consider when purchasing a pump?
When selecting, you need to focus on the following parameters:
- The pressure created by the unit and its throughput.
- Dimensions of the room or platform on which it should stand pump equipment.
- Reliability of the pump from the manufacturer whose device the buyer wants to purchase.
- Financial capabilities of the consumer himself.
Before you go to purchase the desired pump, you need to contact a specialist who will carry out the necessary calculations on the performance of the unit and the required pressure. Such things cannot be decided by eye. Most pumping equipment manufacturers provide such services almost free of charge.
If a person only needs to increase the pressure in the pipeline by 1.5-2 bar, then many companies for this purpose produce compact pumping devices that fit directly into the water supply pipe.
If possible, then instead of one large pumping station, you can purchase several small units of lower power, which are usually turned on right before the liquid entry points and various household appliances, their work should be optimized as much as possible.
Buy pumping units possible at construction markets, in various stores. It is better to go to special branded centers. There the choice is much wider, and it is possible to get free advice on pump parameters and their installation, as well as warranty service.
It often happens that, getting up in the morning and going to the washbasin, we find, instead of a good, powerful stream of water from the tap, only a thin, barely oozing stream. It takes a lot of time to fill a kettle or coffee pot, and performing ordinary hygiene procedures turns into torture. Not to mention that many household appliances, such as a washing machine, simply will not work in such conditions. The problem is serious, but it can be solved by installing a pump that increases the pressure. However, first you need to understand the reasons for its occurrence.
Standards for water supply parameters
Requirements for water supply network parameters in apartment building set out in SNiP 2.04.02-84. According to this document, the water pressure value at the entrance to the apartment must be at least 0.3 atmospheres and no more than 6.0 atmospheres. Conventionally, 1 atmosphere can be considered equal to the pressure created by a water column 10 meters high.
When entering the building, the pressure must be no less than 1.0 atm and no more than 6.0 atm. For buildings with a height of more than one floor, the pressure should increase by 0.4 atm for each floor.
It is easy to calculate that if the number of floors is more than twelve, these requirements will not be met. To provide normal pressure V upper floors, for example, on the sixteenth, at the entrance to the house it should be equal to:
1.0 atm + 0.4 atm*16 fl. = 7.4 atm
This value is higher than the maximum permissible established by SNiP. To comply with all regulations, multi-storey buildings pumps are used to increase pressure. They are installed in technical rooms houses immediately after the water supply entry point. Such pumps pump up the water entering the building and deliver it to the upper floors, providing.
Often, booster pumps for water supply are used in buildings with more than five floors. In such cases, it is more often necessary to use them for injection cold water, since the pressure in the pipeline with hot water supported by pumps installed in boiler rooms.
Often, even in buildings with a small number of storeys or in multi-storey buildings With booster pumps, the water pressure in the apartment is insufficient. The reasons for this can be very different.
Owners of private houses also often face the problem of insufficient pressure in the system autonomous water supply. In this case, it is also necessary to find out the cause and install the appropriate equipment.
Reasons for low pressure
There can be many reasons for unsatisfactory pressure:
- clogged filters for coarse mechanical cleaning water installed at the entrance to the residential premises;
- underestimation of the calculated diameter of pipes or its reduction due to the build-up of deposits on the internal walls;
- presence of defects or malfunctions shut-off valves at the entrance to a house or apartment;
- the presence of faults in the main water supply and loss of pressure due to leaks;
- non-compliance of water supply with standards due to the fault of the water supply organization, which usually services the pipelines.
In most cases, you should first eliminate the root cause, and then think about purchasing a pump to increase the pressure.
Clogged filters are detected by disassembling and inspecting the filter element. Typically, this is a brass mesh rolled into a cylinder shape. It may be clogged with large pieces of rust and scale that got into the pipeline during repairs. The mesh must be washed and replaced.
In high-rise buildings
Underdiameter main pipeline perhaps when several more large consumers are connected to the existing water supply network, which were not taken into account during the design. This could happen, for example, if several lower floor apartments are converted into non-residential premises, used as hairdressing salons, laundries, SPA salons. Water consumption in such premises, especially during the day, can increase many times over.
Sediments can accumulate on the walls of pipes due to poor preparation of water for domestic needs. Water that is too hard, that is, containing a lot of calcium, when heated, releases this element and it, especially in a hot pipeline, is deposited on the walls of the pipes. In both cases, if the diameter of the pipes is insufficient, their replacement is necessary.
If there are faults in the pipelines, they must be eliminated, and then the parameters of the water supply system must be checked again.
The dishonesty of the water supplier can be identified if all previous causes have been eliminated and the pressure in the water supply has not increased. To do this, you need to monitor the pressure throughout the day in all rooms. It often happens that suppliers turn off some of the electric pumps that are supposed to increase pressure at night or in the middle of the working day. At this time, water consumption in urban residential areas decreases, and such a shutdown helps save energy for the organization, significantly reducing its operating costs.
In a private house
In a private house with an autonomous water supply system, everything is a little different. As a rule, water is supplied either by a deep-well pump from a well or by a pumping station with a centrifugal vane pump from a well. In the event of a drop in pressure, it is necessary to check the productivity of the well, the serviceability of the pump, and at the pumping station you also need to check the condition of the hydraulic accumulator, which is responsible for maintaining the operating pressure.
Often deep well pump in an autonomous water supply system it is designed for high performance. His task is to raise as much as possible more water from the lower horizon. The depth of the water can be 120-140 m, and such a pump may no longer cope with the rise of water to the upper floors of the cottage. In this case, it is also necessary to connect a pump to the system to increase the pressure.
Which pump to install
To pump up water pressure you can use various options equipment. If you are going to install a pump to increase water pressure in an apartment, then the choice should be based not only on performance and other functional characteristics. The noise level emitted by the unit during operation is also important. In a private home, you cannot always rely on this indicator, since it is possible to install equipment to increase pressure in various utility rooms.
The pump performance should take into account the number of people living in the house. The calculation may be based on housing and communal services standards, which require the use of 200 liters of cold water and 100 liters of hot water per person per day. Of course, such a flow rate is unlikely to be in demand, but a pump with better characteristics than required during operation will work much longer, and the increase in price will be insignificant.
When choosing pumps to increase water pressure in a private house with several floors, you must take into account the possibility of creating the pressure necessary to lift water to the upper floors.
Control method
Depending on the control method, pressure booster pumps can be manual or automatic.
Hand pumps are turned on for the time required to supply water and then turned off. Such options are used to fill storage containers. Similar water supply schemes are also used in private homes. The inconvenience is that the operation of the pump must be monitored and turned off in time to prevent unnecessary waste of water or running dry.
Booster pumps, equipped with special sensors and controllers, can be turned on and off depending on the conditions created by operating modes. Automation, based on the readings of pressure sensors, will determine when a vacuum appears in the water supply and turn on the pump. If all shut-off equipment is closed and the pressure reaches the control value, the pump will turn off. The automation will also protect the pump from running dry if the water supply to it suddenly stops.
Design differences
The operating principle of pressure boosting units also differs. They can be circulating, which are included directly in the pipeline, or they can be suction - lifting water and directing it into the main line.
Circulation pumps are used primarily to increase the pressure in the heating system, but with some tolerances they can also be used to increase the pressure in the water supply system.
Installation of such pumps is carried out in pipeline breaks, and they, using a rotary impeller, accelerate running water. Such pumps are very quiet, but their performance is low.
Centrifugal pumps can be used to lift more water to greater heights and also to increase pressure. The working body in them is the impeller, which is installed in a housing that looks like a snail. Experts call it that among themselves. Water entering through the central hole of the volute is accelerated by a rotating impeller and thrown out under the influence of centrifugal force through a side hole, entering the pipeline.
Suction pump operation diagram
The operation of the suction pump is based on creating a vacuum in the intake pipe. Such pumps can lift water from wells and shallow wells. When assembled together with a hydraulic accumulator, such a pump can turn into a full-fledged pumping station, which is capable of lifting water several tens of meters.
Vacuum is created when the pump impeller rotates. Depending on its design and engine power, the suction depth can vary, but rarely exceeds 8 meters.
The horizontal distance from the pump to the well also affects the suction depth.
To correctly take this characteristic into account when choosing equipment, you must use the formula:
where H is the maximum possible suction depth,
L – distance from the pump to the water intake,
h – height difference between the pump installation location and the water level.
The h value can increase or decrease depending on weather conditions or time of year. When calculating, you need to take into account the lowest position of the water in the well and take the maximum value of h in the formula.
Features of pumping stations
To organize an autonomous water supply for a private home, it is advisable to use pumping stations. According to their design and principle of operation, they can be submersible or suction. The first ones are installed in a well and are intended for water supply to houses with permanent residence. The latter can be dismantled if they are not used for a reason seasonal residence in houses. Depending on the chosen scheme, pumping stations may differ in design and equipment.
For schemes using a storage water tank, a simple submersible pump is suitable, which can be turned on and off manually, especially with a large tank volume. You can improve the design of the pumping station by installing float water level sensors in the tank. The advantages of this scheme are that it makes it possible to use the water supply even when there is no power to the electric pump for some reason. If storage capacity is large enough, it is possible to experience significant interruptions.
Note! Pumping stations with hydraulic accumulators are more often used. These are metal two-volume tanks in which the cavities are separated by an elastic membrane.
Gas is pumped into one cavity, creating pressure in the pipeline as it is compressed. Water from a source is pumped into another cavity by a pump. The design of the hydraulic accumulator has a pressure sensor that turns off the pump when the maximum calculated value is reached, and turns it on when the pressure drops when the collapsible fittings open in the pipeline. This ensures automation of the water supply process.
The capacity of the hydraulic accumulator is selected based on the volume of water consumed. The size of the tank determines how even the pressure will be when using the water supply, how often the pump will turn on, and how much pressure reserve in the accumulator will be sufficient if the power to the pump is suddenly turned off.
Hydraulic accumulators can be used to create pumping stations with both submersible and suction pumps. When using the latter, it is advisable to equip the station with a check valve, which is installed at the end of the suction hose.
Power selection
The power of the pressure boosting pump must be selected based on the conditions in which it will have to operate and the requirements for parameters and characteristics. The pump must provide comfortable conditions for hygiene procedures, as well as for work household appliances, which requires water supply with certain parameters.
For normal operation of the shower, a pressure of 1 atm is usually sufficient, which must be provided on the top floor of the building. To operate a washing machine or dishwasher, higher pressure is required. To determine which pressure boosting unit to install at the water supply inlet, you need to carefully study technical documentation all available devices.
Note! Having chosen a pump based on pressure and performance, you must make sure that the existing electrical network is suitable for operation.
Pump installation
Installation should be done in a location where it is possible regular maintenance. It should be noted that many booster pumps make noise during operation. If there utility rooms, well isolated from residential areas, there will be no problems, but if the boost pump is installed in small apartment, careful consideration must be given to deciding where to mount this unit.
In some cases, the option of installing inside a closing door slightly reduces noise. kitchen table. An even greater result can be achieved if during installation you use a porous rubber gasket installed between the pump and the base.
When connecting to a pipeline, it is necessary to provide for the possibility of quick dismantling for repair or replacement in the event of a breakdown. To do this, you must use detachable fittings.
Famous models
The most common manufacturers of pumps for increasing pressure and pressure are traditionally Grundfos, Jeelex, Wilo.
One of the best pumps can safely be called Grundfos UPA 15-90 (N). This device, consuming only 120 W of electricity, is capable of minimum pressure at 0.2 atm, raise water by 8 meters, while providing a flow rate of up to 1.5 m³/h. The pump is very quiet, the noise level is only 35 dB. Service life up to 10 years.
For users who are more demanding in terms of performance, we can recommend the Wilo PB-201EA model. This pump is capable of delivering a capacity of 3.3 m³/h, lifting water to a height of up to 15 meters. Noise level during operation: 41 dB. Service life up to 10 years.
One of the most powerful units Jeelex Jambo 70/50 N-50 N is a suction pumping station for lifting water. Provides a flow rate of 4.2 m³/h with a lift height of up to 50 meters and a suction depth of up to 9 meters. Power consumption of the electric pump is 1.1 kW. The device is equipped with a 50-liter hydraulic accumulator.
Boosting pumps water in the water supply system refers to household pumps. They are in great demand nowadays. Often, due to low water pressure, various household appliances may not work, or it is simply difficult to take a shower or run a bath. What can we say about such an important matter as washing dishes?
This device is a real solution to the problem of water pressure in a city apartment or in a private house - it increases the water pressure in the system to the required level and stabilizes it.

Ecology of consumption. Estate: The lack of sufficient water pressure in the system is, of course, not a disaster, but there is little pleasant in such a situation. If you can't wash the dishes or take a shower, then household appliances, such as a washing machine or dishwasher, may simply refuse to work. Fortunately, to solve this kind of problem, pumps have been invented to increase water pressure.
The lack of sufficient water pressure in the system is, of course, not a disaster, but there is little pleasant in such a situation. If you can't wash the dishes or take a shower, then household appliances, such as a washing machine or dishwasher, may simply refuse to work. Fortunately, to solve this kind of problem, pumps have been invented to increase water pressure.
How it works
problem low pressure in water supply systems are solved using two types of devices: circulation and self-priming pumps. The first ones are simpler and easier to install into the system. A conventional circulation pump consists of a rotor, an impeller attached to it and a motor that rotates it all. Usually, if there is water in the system, but its pressure is weak, one or two pumps are enough.
The problem of increasing pressure in the water supply system is solved in two ways: by installing a circulation or centrifugal self-priming pump
But if water does not flow to the upper floors at all, you will have to install a high-power pumping station with a hydraulic tank. Such a device is simply installed as part plumbing system in a suitable place. The impeller rotates, giving the water flow additional acceleration.
As a result, the pipes fill with water faster, providing the required level of pressure in the water supply. These are compact devices low power designed to solve local problems. Suction pumps differ more high performance and a more complex device.
In addition to a suction pump capable of pumping water to a considerable height, the system is also equipped with a hydraulic accumulator equipped with a special membrane. The operation of this equipment is automated; a pressure switch is used. The water is first supplied to the storage tank and then enters the water supply system, providing required characteristics inside the system.
Thus, if a centrifugal pump eliminates a problem in a particular area, then suction equipment is used to regulate the entire water supply in a house or apartment. Self-priming booster pumps are capable of lifting liquid to a height of up to 12 m, while their power starts from 2 kW/h.
The pressure boosting pump works as follows. When the water flow reaches 1.5 cubic meters, the motion sensor petal changes position. This causes the pump to turn on automatically. When the water flow stops, the pump turns off. This type of equipment is used both in private cottages and in apartment buildings.
It is especially relevant in high-rise residential buildings, where it is impossible to ensure normal water delivery to the upper floors without a special pump for various reasons. Installing one pump or even a special station with increased power can be a real salvation for residents of upper floors.
Sometimes you have to use not one booster pump, but two or more. Owners of houses in which the plumbing system was initially designed with errors sometimes face this need. In this case, you will have to calculate the cost of reworking the water supply (if such a possibility exists at all) and the cost of installing additional equipment.
A small pumping station installed in front of household appliances will ensure a normal water supply
It should be remembered that special types of equipment are designed for pumping hot water. They are made of special heat-resistant materials, so they cost more than more simple models, designed for contact only with cold water. There are also universal booster pumps that are suitable for both cold and hot water.
The power of a conventional circulation pump is low and it consumes less energy than some incandescent lamps. When it is included in the system, you can achieve an increase in pressure by about 2-3 atmospheres. If a more serious correction of characteristics is required, preference should be given to more powerful equipment.
Circulation pumps have the property of working “at a dead end”, i.e. they do not need to be turned off even if all the taps are closed and no water is drawn from the system. Supply pumps operate in approximately the same way to increase water pressure. These devices are similar in design to circulation models.
If such a pump is turned off, water will circulate freely through its body. As soon as power is supplied to the motor, the pump turns on. The impeller begins to rotate and the water pressure in the system increases. If there is a choice between automatic or manual systems, the former is usually preferred.
Comparing the diagram of a water supply system with and without a booster pump allows you to more accurately imagine the installation procedure for such equipment
This type of equipment is more convenient to use and lasts longer because it does not run idle. Take the pump to manual control It makes sense only in cases where it will be used either very briefly (temporary option) or extremely rarely (in the summer, at the dacha, only on weekends).
The diagram clearly shows the design of a wet rotor pump. Water flows around the moving parts of the pump and absorbs excess heat.
The concept of dry and wet rotor refers to information about the cooling system of the device. In the first case, it is cooled by a flow of air, and in the second, by a flow of pumped water. A wet rotor pump is cheaper, but lasts less due to negative impact sediment that accumulates on working parts during pumping of water. Models with a dry rotor cope with their tasks more efficiently and have a longer service life.
Pump power and system needs
The power of the device must be commensurate with the needs of the system. Not enough pressure is bad, but you don't want too much pressure either. If a pump that is too efficient is selected for the water supply system, the pressure in the system will increase and all its elements will be subjected to unnecessary additional load. This leads to rapid wear and frequent breakdowns.
The water pressure in the system must be no less than two atmospheres. This is enough for comfortable water procedures, as well as to start an automatic washing machine. Although some models are more demanding in terms of operating conditions. For example, if the house has a shower, hydromassage, jacuzzi or other similar devices, the pressure should be higher.
In this case, it is better to increase the pressure in the water supply system to 5-6 atmospheres. Selected species technology requires even more high performance. Therefore, the first step before installing a pressure booster pump should be to study the documentation of household appliances. If you plan to purchase any devices in the future, their characteristics also need to be taken into account.
To create a permanent high pressure The system uses special pumping stations, including a pump and a hydraulic tank. Their operation is controlled using a pressure switch
A specialist can make accurate calculations, but usually preliminary data made “by eye” is sufficient. To determine how much pressure actually exists in the system, you can use a regular liter jar. They open the water and measure how many liters of water pour out of the tap within a minute.
Then you need to deal with your current needs. If the inconvenience is due to the fact that when the tap in the kitchen is open it is difficult to take a shower due to low pressure, it is enough to use a regular pump, which will increase the pressure by a couple of atmospheres. But if the house has an automatic washing machine, shower cabin or other equipment of this kind, you should study the technical documentation.
Each such consumer requires a certain water pressure. Lack of sufficient pressure can lead to expensive equipment running idle. Household appliances, especially foreign ones, are not designed for such operating conditions. A breakdown caused by a lack of normal pressure may be considered a case that does not comply with the warranty conditions.
You can focus on the maximum pressure indicators in the water supply system indicated in the device data sheets. If you have a large number of such equipment, you should seek advice from an engineer. When choosing a water pump model suitable for power to increase pressure, you should also take into account the needs of equipment that you plan to purchase in the future.
How to install a self-priming pump
Installing a pump of this type is not particularly difficult. To do this, you will need approximately the same skills and tools that are needed to install other types of pumping equipment. Schematically, the installation of a booster pump can be represented in the following steps:
- Choosing a location for the accumulator and pump.
- Installation of a hydraulic accumulator.
- Installation of pipes for connecting equipment to the water supply.
- Hanging the pump from the wall.
- Pump and accumulator piping.
- Checking the operation of equipment in automatic mode.
In fact, a pump and accumulator with a pressure switch is a variation of a pumping station. To implement the installation of such a system of devices, you first need to find a place to place the tank. Some craftsmen replace the hydraulic accumulator with a membrane with an ordinary large capacity, for example, a 200-liter plastic tank.
Instead of a pressure switch, the tank is equipped float sensor to ensure it is automatically filled as needed. Such a tank is installed as high as possible: in the attic or on the top floor. You should immediately think not only about the size, but also about the configuration of the container.
A flat and narrow tank will take less space than the traditional cylindrical model. Although there are no special requirements for the configuration of the container. When choosing a location for a container, you should provide access to the tank/hydraulic accumulator or the ability to easily dismantle this element. This is necessary to complete Maintenance, repair or replacement of the device.
The photo shows the installation of check valves when installing a plastic tank, as well as the procedure for connecting the inlet and outlet pipes to the water pipe
Hydraulic accumulators are supplied ready for installation, but the tank should be prepared. There are holes in it for water inflow and intake. You can also make a separate shut-off valve to drain the water into emergency situation. The pipes for supplying water to the tank and taking it into the water supply system are mounted to one water pipe.
IN modern conditions For the installation of water supply, it is more logical to use easy-to-install and reliable plastic pipes. To prevent air from being sucked into the tank from the pump, and also to prevent water from entering there when the equipment is turned off, both pipes should be equipped with check valves. After this, pipes are installed to connect the tank to the water supply system.
Circulation pumps take up minimal space and do not interfere with the maintenance of household appliances
After the tank or accumulator has been installed and the necessary installations have been carried out water pipes, you can begin installing the suction pump. Typically, such a device is supplied disassembled. It is first assembled and then installation begins.
If you decide to mount the pump on the wall, you should first make markings for the fasteners. The pump is then suspended and connected to the water supply pipes. Overall it's not too much complex operation. Important point- direction of fluid in the pump. It is indicated on the body with special marks.
The pump should be installed in such a way that the water flows from the tank to the water collection points. Thus, the installation and connection diagram for the pressure booster pump is as follows: hydraulic accumulator-pump-consumer. Then the pump is connected.
All connections must be carefully sealed. If you use a booster pump to connect threaded connections, you should use a suitable sealant: FUM tape, linen thread, etc. The amount of sealant should be sufficient, but not excessive. TO plastic pipes the device is connected using special fittings.
After this, you should check the operation of the entire system. If a tank with a float sensor was used, fill it with water. They check not only the operation of the sensor. A container that serves storage tank, should be checked for leaks. If everything is in order, you can proceed to testing the operation of the pump itself.
The pump must be connected to electrical network. It is recommended to move the pump switch lever to the position corresponding to automatic mode. All that remains is to open the nearest water tap and observe the operation of the device. If the installation is done correctly, the pump should automatically turn on and the water pressure will increase noticeably.
Pressure boosting circulation pumps are installed in a similar manner. They choose for them appropriate place in the water supply, and they cut it right there. In this case, it is also extremely important to connect the pump correctly, taking into account the direction of fluid flow. If the position of the device is incorrect, the pump will still allow a flow of water.
Connection diagram of the circulation pump to the water supply system. Installation of such a device is very simple, but it is important not to confuse the direction of water flow
But its work will be extremely ineffective, since the device simply will not function. It is detailed in the instructions and on the case correct position pump After installation, the pump is connected to the electrical network and its operation is checked. If the water pressure at the nearest water intake point has increased, it means that the installation was completed correctly.
A small pump to increase pressure is simply cut into the system. Usually, to do this, it is enough to remove a piece of pipe of the appropriate length at the beginning of the water supply
Installing a system with a hydraulic accumulator looks a little more complicated. First you need to understand the structure of the entire structure. The pump is connected to the hydraulic accumulator using special hoses. Then a pressure switch is connected, with which the equipment will be turned on and off.
This figure shows in detail the principle of operation of a pump with a hydraulic accumulator and the procedure for connecting it. The pump fills the tank and then turns off
The configuration of such a relay deserves special attention. Before starting work, it is recommended to carefully study the instructions and recommendations of the manufacturer. If the knowledge and skills for high-quality installation and configuration of equipment are not enough, it is better to contact a specialist for advice or completely entrust him with all the work.
To solve a problem with low water pressure in a system, a booster pump is not always necessary. To begin with, it doesn’t hurt to diagnose the condition of the water pipes. Cleaning them or complete replacement can restore normal pressure without additional equipment.
To understand that the problem is in the poor condition of the water pipes, sometimes it is enough to ask neighbors living in apartments on the same floor or above. If their pressure is normal, the pipes almost certainly need to be cleaned. If the picture is the same for everyone, there may be more serious problems affecting the entire plumbing system of the house and even the area.
In high-rise buildings, water sometimes simply does not reach the upper floors. This requires high-power and quite expensive equipment. It makes sense to team up with other residents to share the costs. Good idea- demand a solution to the problem from the organization that receives payment for water supply, since it is the organization that must ensure the supply of water to the consumer.
The lack of water on the upper floors is a violation of fire safety requirements. When communicating with a water supply service provider, it is worth paying attention to this point and mentioning the possibility judicial trial due to non-compliance with legal regulations.
It is best to entrust the installation of equipment in an apartment building to a full-time plumber. management company. He is also better familiar with the system, and will be responsible in case of leaks or breakdowns caused by poor installation of equipment.
