The water pressure booster pump is a very important part of the water supply system. They are mounted in individual and centralized systems, since increasing the pressure force improves productivity. They are also very often used in everyday life, because this problem may cause numerous problems with full functioning technical devices in the house, such as: washing and dishwasher, speakers, etc. In our article we will discuss the features of its work, types and advantages.
To denote the concept of pressure, two quantities are used:
Important! The ratio of these two quantities is displayed in the following diagram: 1 bar = 1.197 atmospheres = 10.19.
There are standards for pressure in city water supply systems, according to which it should be 4 atmospheres. Today, pressure drops can be frequent and high and can destroy your devices, because 6-7 atmospheres have a destructive effect on the system. Imported modern technology is especially sensitive in this situation. If the pressure, on the contrary, is low enough, this may affect the operation of the washing machine and dishwasher.
Important! The lowest indicator for the work of elementary equipment should be no lower than 1.5 atmospheres, and for the work of firefighters - 3 atmospheres.
If you are going to buy a pump to control water pressure, then you need to determine the problem. The most popular complaints about water supply systems are:
The first problem can be solved by installing a pump, but for the second it will be useless. In such a situation, it is necessary to install a pumping station.
Normalizing the operation of an autonomous water supply system takes a very long time. Although many people believe that for this it is enough to make a well and install a pump in it, it is important to know that the water temperature is very low, so it has to be stored in a container, and because of this the pressure pressure may drop. To get out of this situation, a flow mechanism was invented to increase pressure.
Their direct purpose is to completely optimize the pressure level in the water supply system in a house or apartment. They are in highest demand on individual plots. Sometimes such pumps are installed to maintain technical requirements devices.
Design features are manifested in hardware complex, which consists of several units - an electric motor and a pump. Features of the scope of application require the use of optimal materials, such as:
Attention! It is worth noting that all of the above materials have a common feature - resistance to corrosion.
The pump body is almost completely immersed in water, therefore it has two sockets in its structure:
It is also worth noting that a wet-type rotor is installed here, which helps reduce the temperature of the installation elements. This item gives the device two advantages:
Attention! Today, there is equipment with blade coolers, which are much more efficient, but also have more noise during operation.
This type of device has a large number of advantages in their performance, which reflect the ease and comfort of their operation:
The following factors may influence the decrease in blood pressure:
For multi-apartment buildings, such situations can be easily resolved, but for individual systems, a device for increasing pressure will be the most optimal solution to the problem.
If the pump works in conjunction with the storage tank, then they can easily cope with the problems of water intake. Such a scheme has a huge number of advantages in operation, especially for a surface or submersible apparatus.
When installing a pressure booster pump, not everyone makes correct calculations of its performance, and this is very important detail. After all, if the indicators of the device and the highway do not match, then the effect may not appear. First of all, this is due to the fact that installation of the device does not increase the pressure of the main line, because it combines several water intake points. The net result will be a reduction in fluid supply.
Attention! If your neighbors already have such a pump, then they are reducing the level of your flow of cold and hot water. You need to pay attention to this. Indeed, in this situation, the pressure increase device begins to work at its maximum, which reduces its life cycle.
For best result efficiency of the device, it is necessary to mount it together with a special tank.
If the room does not have the parameters to accommodate this installation, then you can install submersible pump, which is placed in a container. Its main advantage is the compact size and silent performance of the system. In addition, it has a membrane storage area, which can be part of a central or main system.
It is also worth highlighting the disadvantages of functionality - this is a more complex installation. In addition to connecting to the main line, you also need to configure the automatic operation.
Advice. To avoid mistakes, you need to use standard connection mechanisms or use the services of professionals. But, do not forget that if your pump fails due to improper installation, the warranty will no longer apply and you will have to carry out repairs at your own expense.
The problem of unstable pressure covers a large number of areas of human activity, so the market segment contains a large number of models for different purposes and distinctive volumes. As for the size, there are compact devices for domestic installations and large ones for industrial applications.
Now we will take a closer look at these types.
These types have a number of advantages:
Attention! Household devices function optimally in a temperature range from -15 to +100 degrees.
Pumps are also divided according to such criteria as control type:
What is this mechanism? This is connecting and turning off the system independently, which provides some inconvenience for operation.
It is also worth highlighting the advantages of this type of equipment:
The automatically controlled pump starts working as soon as the fence opens, and its volume instantly collects data on the flow sensor. When closing occurs automatic shutdown tap. This mode prevents dry operation of the device, which increases its life cycle. It is worth highlighting the disadvantage of the system - its high price.
But this is not a huge minus for the performance of the device, since it has a huge number of significant advantages:
There is also a classification according to such a criterion as the method of cooling the housing, which can occur during the operation of the impeller or pumped water. The following types are distinguished:
Attention! There are also universal models that are suitable for working with any water temperature.
Today, there are a number of leaders in the production of pressure boosting devices for water systems. They all have general scheme buildings, but made of different materials. Let's take a look at them:
Individual characteristics of models that you should pay attention to when buying a pump:
When choosing a pump, you must know the system pressure and performance. You can find out these values yourself or hire a specialist. Let us give you a small diagram so that you understand the deduction system. If the pressure in the system is 1.5 atmospheres, then a compact device that can be installed in the pipeline is suitable for its maintenance.
Advice! Purchase pumps from licensed sales outlets.
If your home is on a mains system, then this must be taken into account when installing the pump. It’s just that not only you, but all your neighbors may have such equipment - this will lead to the fact that the mechanism will work at full strength, and the pressure will not increase. In addition, this situation can lead to its breakdown.
Advice! To avoid this situation, you need to install a storage tank in which reserve water will be stored. This liquid is very useful when reducing pressure.
You open the tap and water flows out of it in a sluggish stream. It’s still enough to wash your hands or rinse the dishes, but it’s no longer possible to take a full shower. The situation is even worse with complex household appliances - gas water heater it simply does not start, and the notorious “Error” is displayed on the displays of the washing machine or dishwasher.
The situation is very sad, but, alas, quite common. Residents of apartments in city high-rise buildings face this problem to a greater extent - during peak water collection hours, the pressure in the water supply on the upper floors drops sharply. But owners of houses “on the ground” connected to city water supply networks are not at all immune from this - we have to admit that the quality of public services is often still very far from acceptable indicators. This means that some measures need to be taken.
It would seem that the solution is obvious. It is necessary to install a pump to increase the water pressure, and the problem will go away on its own. However, such a measure often becomes a “half solution,” that is, it does not completely resolve the issue. And in some cases, installing just such a pump becomes a waste of money, since a more in-depth, systematic approach is required.
IN technical documentation pumping equipment, in articles and descriptions on this topic, on instrument scales, different units of pressure in the water supply may be used. To immediately clarify this issue, here is a small table that will help you navigate in the future:
| Bar | Technical atmosphere (at) | Water column meter | Kilopascal (kPa) | |
|---|---|---|---|---|
| 1 bar | 1 | 1.0197 | 10.2 | 100 |
| 1 technical atmosphere (at) | 0.98 | 1 | 10 | 98.07 |
| 1 meter of water column | 0.098 | 0.1 | 1 | 9.8 |
| 1 kilopascal (kPa) | 0.01 | 0.0102 | 0.102 | 1 |
We don’t need too high an accuracy at the everyday level, so to assess your conditions, with a completely acceptable level of error, you can get by with an approximate ratio:
1 bar ≈ 1 at ≈ 10 m aq. Art. ≈ 100 kPa ≈ 0.1 MPa
So, what pressure is considered normal for a home plumbing network?
According to current regulations, water must be supplied to the end consumer at a pressure of approximately 4 bar. With this pressure, the operation of almost all existing plumbing and household appliances will be ensured - from ordinary taps and flush tanks to hydromassage showers or bathtubs.
However, in practice such even pressure is extremely rare. Moreover, deviations to a smaller or larger direction can be very significant. Both phenomena can seriously affect the correct operation of the home water supply system. Thus, if the threshold of 6–7 bar is exceeded, depressurization may occur at pipe connections and at shut-off and control valves. With surges up to 10 bar, there is a high probability of more serious accidents.
But dealing with high blood pressure, in principle, is not difficult - just install it at the entrance to your house or apartment special device, a reducer that will equalize the pressure in the internal distribution of the water supply system and eliminate the phenomenon of water hammer. If you select or configure the reducer correctly, the optimal water pressure will be maintained at all water intake points.
The problem is much more acute if there is a systematic lack of water pressure in the system. And here, first of all, it’s worth trying to figure out what is causing this phenomenon. Well, for this you need, first of all, to have a clear idea of what the pressure is in your local home water supply, whether it changes depending on the time of day or the point of water supply, how things are, for example, with neighbors on the landing and on the riser - above and below . Such information will greatly clarify the picture.
The easiest way, of course, is to measure pressure using a conventional pressure gauge. Such a device is not so expensive, and it makes sense to install it permanently at the entrance to an apartment or house. Even better - install a mesh at the entrance wash filter rough water purification with a built-in pressure gauge - two problems are solved at once. All that remains is for a certain period to regularly take and record readings approximately four times a day - during peak consumption hours in the evening and morning, in “normal” daytime and at night. Then a preliminary analysis of the situation can be carried out.
You can have a portable pressure gauge on your farm or rent it from friends. It is easy to temporarily connect it, for example, using a flexible connection, to the water sockets of faucets or even directly to the spouts, if the threaded connection allows.
You can also make a homemade simple pressure gauge, which, despite the primitive design, is nevertheless capable of giving very accurate results.
To make such a device, you will need a transparent plastic tube about 2000 mm long. Its diameter of great importance does not have one - the main thing is that it is convenient to make a sealed connection with a fitting that will be screwed, for example, onto a faucet spout instead of a divider nozzle.
Before starting the measurement, the tube is connected to the tap (in principle, it can be any other water outlet) and is positioned vertically. The water is started briefly, and then a position is achieved so that the liquid level is approximately on the same horizontal line with the connection point, so that there is no air gap(shown in the diagram - left fragment). In this position, the height of the air section of the tube is measured ( ho).
Then top hole The cabin is tightly closed with a stopper to prevent air from escaping. The tap is opened fully. The water, compressing the air column, will rise. When the position stabilizes, in a minute or two, all that remains is to measure the experimental height of the air column ( heh).
Given these two values, it is easy to calculate the pressure using the following formula:
Rv = Ro × (ho/he)
Rv– pressure in the water supply at a given point.
Ro– initial pressure in the tube. It would not be a big mistake to mistake it for atmospheric, that is, 1.0332 at.
ho And he – air column height values obtained experimentally
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 real solution water pressure problems in a city apartment or in a private house - it increases the water pressure in the system to the required level and stabilizes it.
The presence of a pump that increases water pressure in the apartment - big advantage, because such household appliances as geyser, dishwasher, washing machine work without failures or breakdowns only if there is stable water pressure.

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.
Requirements for the parameters of the water supply network in an apartment building are 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 ensure normal pressure in the upper floors, for example, on the sixteenth, at the entrance to the house it must 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 standards, multi-storey buildings use pumps that increase pressure. They are installed in the technical rooms of 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 the required water pressure.
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 to pump cold water, since the pressure in the hot water pipeline is maintained 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.
There can be many reasons for unsatisfactory pressure:
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.
Underestimating the diameter of the main pipeline is possible when several more large consumers that were not taken into account during the design are connected to the existing water supply network. 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 daytime, 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 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, a deep-well pump in an autonomous water supply system 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.
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 level of noise 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.
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.
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.
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.
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.
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 the implementation of hygiene procedures, as well as for the operation of household appliances that require 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 must carefully study the technical documentation of 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.
Installation should be in a location where regular maintenance is possible. 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 booster pump is installed in a small apartment, you need to carefully consider the decision about where to mount this unit.
In some cases, the option of installing it inside a closing kitchen table slightly reduces noise. 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.
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 raising water by 8 meters at a minimum pressure of 0.2 atm, 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.
Perhaps you have ever encountered a situation where water flows from a tap in a very weak stream. At the same time, it’s inconvenient to wash dishes, and there’s no need to even talk about taking a shower. But the inconvenience, unfortunately, does not end there. If the water pressure in the tap is low, it is impossible to start a gas water heater; washing machines and dishwashers may also “refuse” to work in such conditions. As sad as it may be, this situation is quite common. Very often, residents of the upper floors of high buildings suffer due to insufficient water pressure. apartment buildings during peak hours. Owners of private houses also often face this problem, which is explained by shortcomings in the work of public utilities. If you are familiar with the problem described, then know that it has a fairly simple solution: they will help you out in a private house.
Pressure can be indicated in different units of measurement. That is, for example, in the technical documentation of a pump, the pressure can be indicated in MPa, in articles - in kPA, and on instrument panels - in mm of water. Art.
You probably won't need to know exact value pressure in the water supply system, so you can use the following ratio, which will make it easier for you to evaluate the operation of the water supply system in your private home:
1 bar ≈ 1 at ≈ 10 m aq. Art. ≈ 100 kPa ≈ 0.1 MPa.
The standards establish pressure requirements tap water for residents of a private house or apartment - 4 bar. With this value, all household appliances in a private or apartment building will be able to work well.
Unfortunately, few residents of private houses have pressure in their taps at exactly this level. Most often the deviations are significant. Any deviations from the norm are harmful to the water supply system. Thus, a pressure of more than 6-7 bar can lead to depressurization at pipe joints. A jump to 10 bar is fraught with an emergency situation.
The solution to the problem of insufficient or increased water pressure in a private house is to install a reducer that equalizes the pressure in the internal water supply, which eliminates the possibility of water hammer. If you avoid mistakes at the stage of selecting and installing the gearbox, the pressure in the system will always be optimal.
More a difficult situation is a systematic lack of pressure in the water supply of a private home. It is necessary to identify the cause of this problem. Conduct a simple study to find out what pressure in the water supply of your private home is normal and how it changes during the day. After research, the situation will become clearer.
You can measure pressure with a pressure gauge. It is inexpensive, so we recommend that you purchase it and install it on the inlet main of your private home. It will be even better if you buy a mesh wash filter for coarse water purification with a built-in pressure gauge. It is enough to record the device readings 3-4 times a day at certain hours (including peak hours). Then it will be possible to analyze the water pressure in your private home and draw preliminary conclusions.
You can ask someone you know or buy your own portable pressure gauge. Connecting it is not difficult: you can do this using a flexible connection to the water sockets of faucets or to spouts, if the threaded connection is suitable. In fact, you can even assemble a simple, but quite accurate pressure gauge with your own hands.
In order to assemble the pressure gauge, you will need a plastic tube approximately 2000 mm long. The diameter of the tube must be such that it forms a tight connection with a fitting that screws onto the faucet spout, replacing the divider nozzle.
You can accurately determine the water pressure in a private house in the following simple way:
The first step is to connect the tube (vertically) to the faucet (or other water outlet). Then turn on the water and level the liquid level: there should be one horizontal line with a connection point (without an air gap at the tap - see the left figure). Now you can measure the height of the air section of the tube ( h o).
The next step is to close the top hole of the tube with a stopper (so that air does not escape) and open the tap completely. The water will rise. After stabilizing the position, you need to measure the experimental value of the air column ( h e).
Now you can calculate the pressure:
P in = R o × (h o / h e)
Where R in– pressure in the water supply at a given point; R o– initial pressure in the tube. It is acceptable to take it as atmospheric, that is - 1.0332 at; h o And h e – experimentally obtained value of the height of the air column.
It may be that the pressure at several different points in the pipeline of a private house varies. This is evidence of the formation of rust or limescale. In this case, it is necessary to replace the piping.
It is possible that the filters used in the water supply of your private home are very dirty or too old. To troubleshoot problems, it is necessary to perform appropriate preventative measures.
On sale you will find different variants pump designs for increasing water pressure in a private house:
circulation pumps for increasing pressure;
self-priming pumping stations to increase pressure.
They are standard devices for increasing water pressure in a private home. They received this name because they accelerate the movement of water in the pipes. Circulating ones are most often small in size, they are very compact. They are installed in sections of pipelines with insufficient pressure.
The developers of pumps for increasing water pressure in a private home had a specific goal - they wanted to come up with a device to improve the operation of systems with hot coolant. This is understandable, since the heating circuits have an impressive length, and there is resistance at the node connections. Without the use of pumps, such systems will not function effectively.
If we talk about water supply, then the essence is the same, with the only difference being that the pump accelerates the movement of water, and does not pump up hot coolant.
A circulation pump for increasing water pressure in a private home consists of a motor that drives a rotor part with an impeller. Thanks to these elements, the pump accelerates the movement of water in the chamber and significantly improves the characteristics of the pipeline as a whole.
The installation consists of a surface pump and a hydraulic accumulator. A surface pump pumps water into a hydraulic accumulator, which has an air membrane and check valves, with the help of which the pressure in the water supply system of a private house is regulated and maintained at the required level.
The pressure switch allows you to adjust the value of this indicator and automates processes.
Pumps for increasing water pressure in a private house operate in the following systems:
With cold water;
with hot water.
To increase the pressure of cold water in a private home, simple plastic pumps are used. They work with liquid whose temperature does not exceed +40 °C and do not tolerate prolonged contact with hot water.
Pumps for increasing the pressure of hot water in a private home are more expensive, but can be used in heating and hot water supply systems. They are made from expensive polymers, stainless steel and high-quality rubber.
The circulation pump to increase water pressure is no different high power, but also consumes very little energy.
It increases the water pressure in a private house by 2-3 atmospheres. There are more powerful analogues that pump up to 2-3 m 3 of water per hour.
Significantly more powerful are water stations for increasing water pressure, the self-priming pumps of which consume 2 kW of electricity when operating. They "attract" water from long distance(up to 12 meters).
So, when planning to purchase a pump to increase water pressure in a private house, it is important to determine why it is needed: simply to improve pressure or to raise water to the upper floors. To increase the pressure, a small, low-power pump of an “in-line” design, embedded in the pipeline, is suitable. But if you need to raise the water level, you need a centrifugal water pump high pressure with hydraulic accumulator. The operating mode of such pumps is:
Manual– in which the equipment can operate continuously. It will be necessary to monitor the temperature of the pump itself in order to avoid overheating and failure.
Automatic– in which the pump operation is controlled by a flow sensor. The pump will start the moment water flows from the tap. This is an ideal operating scheme, as it eliminates the need to start the pump to increase pressure in dry mode. Such a pump is more profitable because its service life is longer.
Pumps for increasing water pressure in a private home can be cooled thanks to the motor impeller or the pumped liquid. Here is a classification of pumps depending on the method of their cooling, namely:
Blades mounted on a shaft(dry rotor design). Such engines have a low efficiency value and create little noise during operation.
Liquid(wet rotor). The operation of such pumps is almost silent.
For the homeowner, the size of the pump to increase water pressure is important, since it is necessary to allocate space for its installation.
The advantage of a pump with a dry rotor is high efficiency, and with a wet rotor it is quiet.
As a rule, pumps are installed at the inlet a private house. Note that there are models that can be installed on both cold and hot water supply systems (universal pumps) or for a certain water temperature.
After you check whether the water supply pipes are clogged, you can think about purchasing a powerful self-priming pumping station. Pumps for increasing water pressure in a private home can be equipped with a hydraulic accumulator. More often than not, homeowners prefer without it. However, experts advise choosing pumping stations with hydraulic accumulators.
Station is a surface centrifugal pump for increasing water pressure in a private home. It is connected to a hydraulic accumulator and a pressure switch, which controls the entire system. Using the station, water from the system is supplied to the tank. Thanks to the tank, the consumer always has a supply of water, even if it is turned off, which is very convenient. Gradually the pressure drops, and at a certain point the relay will automatically turn on the pump.
It is more profitable for the tank to be large, since there will be enough water in it for a longer time and, accordingly, starting and shutting down the mechanism will be carried out less frequently, and the equipment will wear out more slowly. Standard scheme connections for a pressure booster pump and a diagram for installing a pumping station in a private house with a nearby well are shown below. Please note that connection is possible to any available water source.
When selecting a pump, consider the following:
what problem should a pump for increasing water pressure in a private house solve;
throughput pumps and the pressure it creates;
How reliable is the manufacturer;
the dimensions of the room where the pump will be installed to increase water pressure in a private house;
how much money are you willing to spend on purchasing such a pump?
If you do not know the required performance and pressure, it will be very difficult to choose the most suitable pump for your water supply system. It would be right if you entrust the calculations to a specialist, especially since it is not difficult to find one: many companies involved in the sale of such devices offer this service completely free of charge.
If you need to slightly increase the pressure (by 1.5 atm), then choose a compact pump to increase water pressure in a private home. It is very easy to install.
It can be cut directly into the pipe. Scheme:
Circulation pump.
Stopcock.
Thermostat.
Safety valve.
It is necessary to choose such a pump to increase water pressure in a private home so that its power meets the needs of the system. When the pressure is insufficient, this is bad, but excess pressure should not be allowed, since the system elements will function under conditions of unreasonably high load, which is fraught with rapid wear.
The minimum pressure in the system is 2 atm. In such conditions, you can safely wash the dishes and start the washing machine(note that some models may be “capricious” and refuse to work in such conditions).
However, if you are used to using hydromassage in the bathroom and lying in a jacuzzi, then the pressure in the system should be higher - 5-6 atm. Some techniques only work at even higher values. Thus, when thinking about buying a pump to increase water pressure in a private home, re-read the instructions for the household appliances you have (and those you plan to purchase in the future).
To obtain accurate numbers, you will need the help of a specialist. Most likely, he will have enough preliminary estimated data to carry out calculations.
Now it is important to understand what problem you want to solve by installing a pump in a private home. If you cannot take a normal shower when someone is washing dishes in the kitchen, then a regular pump will be enough for you to increase the water pressure in a private house (it will provide an increase of 2 atm.). You probably have some Appliances(the operation of which is related to water pressure), so study the instructions for it.
The devices operate normally at a certain water pressure in a private home. If the water supply cannot supply your expensive equipment the right amount water, then it will have to run idle, which will most likely lead to a breakdown of the device that cannot be repaired under warranty.
When choosing a pump, take as a basis the maximum permissible pressure indicators for the equipment (data from data sheets). If you have too many of these household appliances, consult an engineer.
There is an opinion that you should not buy an expensive and powerful pump to increase water pressure in a private home. Proponents of this judgment claim that you should choose a less powerful device that is connected directly before the parsing points and household appliances, whose operation needs to be optimized.
Buying a pump today is easy, since their range is quite wide. We recommend purchasing the device not on the market, but in a company store, where there is plenty to choose from, and, which is important when purchasing expensive models, there is warranty service.
Installation of this type of pump is quite simple. You don't need to purchase any complicated tools to install the equipment. You should follow these steps:
determine the location for the accumulator and pump;
install a hydraulic accumulator;
install pipes to connect equipment to the water supply;
hang a pump to increase water pressure from the wall;
tie the pump and accumulator;
check the operation of the pump in automatic mode.
A pump and hydraulic accumulator with a pressure switch are a variation of a pumping station for increasing pressure in a private house. In order to install it, you will have to think about where exactly the tank can be placed. Some owners of private houses, instead of a hydraulic accumulator with a membrane, install ordinary large plastic tanks (volume 200 l).
In such cases, the pressure switch replaces the float sensor, due to which the tank is filled with water when necessary. Such a tank should be located as high as possible (attic, top floor). It is necessary to think about its most suitable configuration in a timely manner.
To save space, you should choose a narrow flat tank; its shape can be arbitrary. The installation should be carried out in such a way that access to it or to the hydraulic accumulator is maintained (alternatively, it can be made so that it can be easily removed if necessary). This is important, as otherwise difficulties will arise during maintenance, repair or replacement of the device.
A store-bought hydraulic accumulator does not require any preparation for installation, but you will have to create holes in the tank through which water will flow in and out. It would be a good idea to install an additional shut-off valve, with which you can quickly drain the water in the event of an accident. The pipes that take and supply liquid to the water supply system are mounted to one water pipe.
Nowadays, it is most convenient to use plastic pipes for assembling a water supply system: they are easy to install and, what is very important, they are reliable. It makes sense to install on pipes check valves: they will prevent air from the pump and water from entering the container when the equipment is turned off.
Now you can begin assembling and installing a suction pump to increase pressure in a private house, which was probably purchased disassembled.
If you decide to mount the pump to the wall, then do not forget about the markings for fasteners. After the device is installed, it is connected to the water supply. This is not difficult, but it is important to carefully monitor the direction of water movement in the device (there should be special marks on the body).
The liquid in the pump to increase water in a private house must move from the tank to the water collection points. In other words, the installation must be connected according to the following scheme: hydraulic accumulator - pump - consumer. The next stage is piping the pump.
Below is a diagram of connecting a pump to increase water pressure in a private house to the water supply system.
Installation is usually carried out as follows: the pipes at the beginning of the system are disconnected and a pump is connected to them (fittings are used for this).
It is important that the connections are tight. If a pump is “screwed on” to increase water pressure in a private house, then threaded connection there must be a sealant in the required quantity (FUM tape, flax thread). To connect the device to plastic pipes fittings will be required.
It is important to check the operation of the system; to do this, fill the tank with the float with water. It is necessary to make sure that the container does not leak, and also check the operation of the sensor. In the absence of these problems, you can test the work yourself.
To do this, connect the device to the network (automatic mode), open the tap and observe its operation. If everything is correct, then the pump to increase water pressure in a private house should automatically turn on, and the liquid pressure should increase significantly.
Installation is carried out in the same way circulation pumps increased pressure in a private home. They are cut into the water supply in a certain place. It is important to consider the direction of fluid movement. If the device is not positioned correctly, water will pass through the pump.
But you will not notice an increase in pressure, since the device will not perform its task. Therefore, carefully read the instructions, it describes in detail correct position pump to increase water pressure in a private house. If the pump connected to the network affected the water pressure, then it means that no errors were made during installation.
Installing a system equipped with a hydraulic accumulator is somewhat more difficult. Before proceeding with installation, it is necessary to carefully study the design of the pump installation for increasing pressure in a private house. The pump is connected to the hydraulic accumulator using special hoses. A pressure switch, which is also connected to it, is responsible for turning the device on and off.
The figure below shows in detail the principle of operation of a pump with a hydraulic accumulator and the sequence of its connection. The pump turns off after the tank is full.
It is quite difficult to configure the relay. Therefore, carefully read the instructions and recommendations of the manufacturer. If you have never done anything like this, we recommend that you consult with a specialist or entrust him with all the work.
Whatever pump you choose to increase water pressure in a private home, you will have to additionally purchase pipes, fittings, connections, etc. Give preference only to high-quality products from reliable suppliers.
