You open the tap - and water flows out of it in a sluggish stream. Washing your hands or rinsing the dishes, with grief in half, is still enough, but taking a full shower is no longer possible. Even worse is the situation with complex household appliances – gas water heater it just doesn’t 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. To a greater extent, residents of apartments in urban high-rise buildings face it - during peak hours of water intake, the pressure in the water supply system on the upper floors drops sharply. But the owners of houses “on the ground” connected to city water supply networks are not insured at all from this - we have to admit that the quality of utility services is often still very far from acceptable performance. So, some action needs to be taken.

It would seem that the way out 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-way solution”, that is, it does not completely remove the issue. And in some cases, installing only such a pump becomes a waste of money, since a deeper, more systematic approach is required.

AT technical documentation pumping equipment, in articles and descriptions on this topic, on instrument scales, various units of pressure in the water supply system can 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 water column	0.098	0.1	1	9.8
1 kilopascal (kPa)	0.01	0.0102	0.102	1

Too much high accuracy we don’t need it at the household level, therefore, to assess our conditions, with a completely acceptable level of error, we can get by with an approximate ratio:

1 bar ≈ 1 atm ≈ 10 m of water Art. ≈ 100 kPa ≈ 0.1 MPa

So, what pressure is considered normal for a home plumbing network?

In accordance with current regulations, water must be supplied to the end user at a pressure of about 4 bar. With such a pressure, the work of almost all existing plumbing and household appliances– from conventional faucets and cisterns to hydromassage showers or bathtubs.

However, in practice, such an even pressure is extremely rare. Moreover, deviations to a smaller or larger side are very significant. Both phenomena can seriously affect the correct operation of the home water supply system. So, when the threshold is exceeded by 6÷7 bar, depressurization may occur at pipe joints, on shut-off and control valves. With jumps up to 10 bar, there is a high probability of more serious accidents.

But it is, in principle, not difficult to deal with increased pressure - it is enough to install a special device at the entrance to a house or apartment, a gearbox that will equalize the pressure in the internal wiring of the water supply system and eliminate the effects of water hammer. With the correct choice or adjustment of the reducer, the optimal value of water pressure will be maintained at all points of water intake.

The problem is much more acute if there is a systematic lack of water pressure in the system. And here, for a start, it is worth trying to figure out what is the cause of this phenomenon. Well, for this it is necessary, first of all, to have a clear idea of what pressure is in your local home water supply, whether it changes depending on the time of day or the point of draw-off, how things are, for example, with neighbors in the landing and in the riser - above and below . Such information will help to clarify the picture in many ways.

The easiest way, of course, is to measure the 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 - to mount a mesh coarse water filter with a built-in pressure gauge at the inlet - two problems are solved at once. It remains only for a certain period to regularly take and record readings about four times a day - during peak consumption hours in the evening and in the morning, in "normal" daytime and night mode. Then it will be possible to conduct a preliminary analysis of the situation.

You can have a portable pressure gauge on the farm or rent from friends. It is easy to temporarily connect it, for example, with a flexible hose, to the water sockets of mixers or even directly to the spouts, if the threaded connection allows.

Can also be made homemade simple manometer, which, despite the primitive design, is nevertheless able to give very accurate results.

For the manufacture of such a device, a transparent plastic tube with a length of about 2000 mm is required. Its diameter of great importance does not have - the main thing is that it is convenient to make a tight connection with a fitting that will be screwed, for example, onto a tap 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 placed vertically. A short-term start-up of water is carried out, and then such a position is achieved that the liquid level is approximately on the same horizontal line with the connection point, so that there is no air gap from the side of the tap (shown in the diagram - left fragment). In this position, the height of the air section of the tube is measured ( ho).

Then the top opening of the cabin is tightly closed with a cork to prevent air from escaping. The faucet is fully open. Water, compressing the air column, will rise. When the position stabilizes, after a minute or two, it remains to measure the height of the experimental air column ( he).

With 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 is the initial pressure in the tube. It will not be a big mistake to take it for atmospheric, that is, 1.0332 at.

ho and he - experimentally obtained air column heights

Calculator for experimental determination of water pressure

Enter the results of two measurements and get the result

atmospheric

ho - height of the air column before opening the valve, mm

he - the height of the air column with the valve fully open, mm

If measurements are taken at several points, and the readings are different, then this is a sure sign that possible reason insufficient pressure on a particular plumbing or household appliance lies in defects in the internal wiring of the water supply system itself. It is possible that the old pipes are overgrown with rust or limescale, and no additional equipment will change the situation - you will have to change the piping.

To demand normal pressure from such a water supply system is simply naive

The reason for the drop in pressure can be filters that have not been changed or cleaned for a long time - and carrying out appropriate prevention immediately puts everything in place.

You should compare the readings with similar parameters in neighboring apartments located on the same level - they should be approximately equal. Sometimes this helps to identify the problem that lies in the water riser.

It would be nice to find out the state of affairs in the neighboring apartments vertically - how much the problem of low pressure affects them. As the floor height increases, the pressure (in meters of water column) should decrease by approximately the excess value.

And, finally, if, of course, it is possible, it is advisable to find out the pressure on the "sunbeds" of the house, that is, on the collectors in the basement, to which the risers are connected along the porches. It is possible that the public utilities fulfill their obligations, and the water pressure to the risers is normal.

This means that the area of \u200b\u200bthe problem will be localized - often the “pilot” of all the troubles becomes the owner of the apartment living down the same riser, who, when carrying out repairs in his bathroom, narrowed the diameter of the pipe for one reason or another - “it’s cheaper”, “it’s more convenient and more beautiful” , “as an experienced plumber suggested” or even “everything is fine with me, but the rest do not bother me.” Here you will either have to agree on a good one, or take administrative measures through public utilities.

If the pressure on the house collector is also weak, you should “get the truth” from the public utilities, since the quality of the service they provide does not meet the requirements. Whether it will be possible to achieve something is still a big question, since you can hear a lot of reasons: from requiring replacement of main pipelines to the inability to currently install new pumping equipment to replace obsolete ones.

What can be done?

If all the steps taken of the “administrative plan” have not yielded results, and there is not enough pressure to ensure the correct operation of plumbing and household appliances, technological measures will have to be taken. Here you will need to install one or another additional equipment. But, again, to say that a pump to increase water pressure will become a panacea would be naive.

Such a measure will become effective only if the water always flows almost uninterrupted, but its pressure is not enough to trigger household appliances. For example, the owner of a private house connected to the main, in which there is constantly a pressure of no higher than 1 - 1.5 bar, may well be able to install a pump at the entrance to the house or even in front of the draw-off point, which requires higher rates. To some extent, this is also acceptable in urban high-rise buildings, but again - with a stable water supply, but with a "deficit" of pressure.

If the "failures" of pressure reach the point that on the upper floors there is often a complete disappearance of water from the taps, the booster pump will not justify itself. Firstly, he needs to “lean” on the minimum allowable pressure in the pipe for this model in order to give the desired value at the output, and he cannot create anything from the void. Secondly, by increasing the pressure, the pump necessarily creates a certain vacuum behind. In case of insufficient pressure, open on any ground floor the tap turns into a "hole" through which air can be sucked in. The pump will start trying to pump air, and in the best case, if it is equipped with a dry-running protection system, it will simply turn off all the time, but if not, it will quickly burn out. And thirdly, by somehow improving the situation in his apartment, the owner of the pump unwittingly worsens the situation in neighboring ones.

What is the way out? There are several of them, but not all of them will be easy to implement.

1. Install a pumping station operating in automatic mode, preferably with a hydroaccumulating membrane tank of the maximum possible volume. The main element of such a station is centrifugal pump self-priming type, that is, capable of independently, even at “zero” inlet pressure, to raise water from a certain depth (for example, from a basement collector or an autonomous source) and create a very significant pressure at the outlet.

The pressure switch, which is usually included in the station kit, will ensure that the pump motor is turned on only when the pressure in the home (apartment) water supply drops below the set level. The storage tank will create a reserve supply of water, which will also be under pressure and consumed in cases where the water supply in the main is temporarily interrupted.

Thus, the pumping station both raises the water up, and creates the necessary pressure in the system, and provides a certain supply of water. The larger the volume of the storage tank, the less often the pump will turn on.

The solution is excellent, one might say - optimal for private households, but in multi-storey buildings, a lot of difficulties can arise with it. If the pressure in the risers is weak, then many residents of the upper floors suffer from this. If they begin to get out of the situation in this way, then a real rivalry “for the stream” will flare up in the house, since the total amount of incoming water will still be insufficient for everyone. Again, the same situation as mentioned above - sucking water out of the pipes will lead to airing with all the ensuing consequences. Scandals and trials are inevitable on this out, “denunciations” against each other to the operating organization or to the “water utility”. And the installation of such a station without the knowledge of public utilities may well result in a decent fine, as the equipment introduces an imbalance in the overall operation of the water supply system at home.

There is one more limitation: self-priming pumps are usually limited in depth (in the case of a high-rise building - height) of water rise - about 7 ÷ 8 meters. That is, for the first or second floor - it will do, the third - already with a stretch, and above - it is unlikely to cope.

2. Install a volumetric non-pressure tank in your home so that it is constantly replenished during the hours of normal water supply, even if with insufficient pressure. The simplest float valve will not allow the tank to overflow.

If such a container for at least 200 ÷ 500 liters can be installed at the height of the ceiling, then water from it will either flow by gravity to the points of water intake, in front of which it is already possible to install conventional compact pressure boosting pumps, or it will be possible to mount a booster at the common outlet of the tank. pump, the power and performance of which will be enough for all consumption devices. As an option - a compact pumping station with a small volume hydraulic accumulator, which will already be powered from a storage tank. In this case, the tank can not be lifted up, but to find for it the most convenient place for the existing conditions.

The main obstacle to the implementation of such a project is the tightness of standard city apartments: there is simply nowhere to install even a small capacity. Again, such an output seems to be optimal for a private developer.

However, it is quite possible that it will be possible to cooperate with neighbors who also have a similar problem in order to install a large-capacity collective storage tank, for example, in the attic of a house. The scheme will be the same - water flows to each apartment by gravity, and then the owners themselves decide at what points they need to install a boost pump.

A possible solution to the problem is with the installation of a collective storage tank

3. The third option also implies cooperation - this is the installation of a powerful pumping station with an impressive storage tank and a hydraulic accumulator for the collected funds, so that the power and productivity of the equipment is enough for the entire riser. Thus, in the basement it will be possible to have a significant non-pressure and pressurized supply of water, and all residents will equally receive it in the right amount and with the required force.

It is clear that this is easy to say, but very difficult to perform, since it can be extremely difficult to persuade people. Nevertheless, there are plenty of examples of such collective interaction of the residents of the house.

Now that the main possible applications of pumps that increase water pressure are considered, we can turn to an overview of the equipment.

Choosing a pump to increase water pressure

So, if the situation can be completely corrected just by installing a pump to increase the water pressure, then you need to know how to choose the right device.

All pumps of this class can be divided into two large groups- These are devices with a dry and wet rotor.

Glandless pumps are more compact, less noisy, do not require any maintenance work, since all moving parts are lubricated by the pumped liquid. They are installed directly into a pipe, for example, in front of a household appliance or a tapping point, and do not require any additional fasteners.

A typical representative of pumps with a "wet rotor"

Their disadvantage is their low performance and the additional water pressure created. In addition, there are restrictions on the installation method - the rotor axis of the pump electric drive must be in a horizontal position.

Pumps with a dry rotor can be immediately distinguished even outwardly due to the pronounced asymmetric shape - a power unit taken out to the side, which has its own air cooling system - a fan impeller located on the axis. This arrangement most often involves additional cantilever mounting of the device to the wall surface.

Pumps with a "dry rotor" usually require additional wall mounting

Such devices usually have higher performance characteristics, and when right choice and the installation is sometimes able to "serve" several points of water intake at once.

Pumps with a dry rotor require regular lubrication of friction units, and during operation they can create, albeit small, but still noticeable noise - this must also be taken into account when choosing a place for their installation.

In general, devices of this class of both types, both in design and in principle of operation and in installation rules, are very similar to circulation pumps that are built into the circuit autonomous system heating. To avoid repetition, the reader who is interested in these issues can be directed to the relevant publication.

What you need to know about circulation pumps?
These compact devices provide a stable movement of the coolant along the contours of the heating system. Read about the device, calculation of the required operational parameters, selection and installation in a special publication of our portal.
The fundamental difference lies in the fact that circulation pumps, as a rule, work in a constant mode while the heating system is activated. Devices designed to increase the pressure in the water supply system do not require such a mode - they should only work when necessary, when it is necessary to provide pressure.
There are two approaches to solving this issue.
Some inexpensive pumps have only manual control - that is, the user turns them on himself as needed. This is certainly not the best approach given the forgetfulness of some people. In addition, if the device, for example, provides operation washing machine, then the water intake for washing and rinsing is carried out periodically, in accordance with the program, that is most pumping equipment effort cycle is not required.
The optimal solution is to install a device equipped with a flow sensor. The pump will start only when the tap is opened and, of course, if there is water in the pipeline. This will unload the device from unnecessary work, and prevent it from overheating or burnout from a “dry run”.

The flow sensor may be included with the pump or purchased separately. It is always installed after the pump in the direction of water movement.
If the water pressure in the water supply is unstable, that is, it can be normal, but becomes insufficient at certain periods, then an optional, but very useful addition can be a pressure switch that is installed at the inlet, in front of the pump.
A useful addition to the wiring diagram is a pressure switch
The pump power circuit in this case is switched through a relay, which can be configured in such a way that it works and turns on the power to the device only in case of insufficient pressure in the system. With normal head pressure, the pump will not turn on even after the flow sensor is triggered.
When choosing a pump, the necessary difference must be taken into account, by which the pressure must be increased for the correct operation of plumbing or household appliances. Do not wait for "outrageous" values - usually this parameter lies in the range of 0.8 ÷ 1.5 bar (8 ÷ 15 meters of water column).
If purchased for installation on a hot water pipe (there are such situations), then its characteristics must correspond to the operating conditions for elevated temperatures pumped liquid. Typically, such information is indicated in the product data sheets.
An important parameter is the performance of the device - the amount of water pumped per unit of time. The performance must be higher than the average flow at the point of consumption before which the equipment is installed.
When choosing a model, of course, you should give preference to "authoritative" brands, while specifying how available service is in your region, and what warranty obligations apply to this device.

Choosing a pumping station
So, the second option for a fundamental solution to the problem of ensuring normal water pressure is to install a pumping station.
This device is a surface centrifugal self-priming pump. It can be conventional or equipped with an injector - this technological addition significantly increases the pump's ability to lift water from a considerable depth, but, however, makes its operation more noisy.
The pumping station may already have a built-in membrane-type accumulator, or this element of the required volume is purchased separately. Required condition- the presence of a pressure switch, but in this case it is already installed after the pump itself - when it reaches in the accumulator threshold pressure, the power supply to the power unit is turned off.
The working pressure in the accumulator is always somewhat excessive - it is calculated in such a way that the correct operation of all plumbing and household appliances is ensured, and at the same time, a certain reserve is also maintained. As the water flows, the pressure drops, and when it reaches a certain lower limit, pre-set by the manufacturer or by the user himself, the relay closes - and the pump again works out the water supply replenishment cycle to the upper threshold.
In fact, the pumping station does not just increase the pressure of water - it creates it itself in a closed home plumbing system and constantly maintains it at a given level. And the presence of a hydraulic accumulator makes it possible to hope for a reserve supply of water in case the supply from an external source (the main network) suddenly stops.
In this case, a flow sensor is not required - the pump does not respond to the current water flow, but to the pressure level in the storage tank.
As a rule, they are equipped with pressure gauges - to make it easier to visually monitor the work.
Installing a pumping station is much more difficult than a conventional tie-in booster pump. It is better not to deal with this issue on your own, but to invite an appropriate specialist.
When installing, it should be noted that there are practically no completely silent pumping stations. This means that it is necessary to provide for a place for it, which, firstly, would be at the entrance to the house or apartment, and secondly, would provide necessary sound insulation for residential premises.
The accumulator can be quite small ...
The hydraulic accumulator included in the pumping station kit can be quite small, literally a few liters. However, it should be remembered that winning in compactness, you can lose in the duration of operation of the device and in power consumption - the smaller the volume of the tank, the more often the pumping unit will turn on and off, the faster its “motor resource” will be consumed.
Nothing prevents you from purchasing a hydraulic accumulator of the required volume - they are also sold separately. For two people, a 24-liter tank is usually enough. For a family of 3-5 people, a hydraulic accumulator with a capacity of 50 liters will already be required.
Well, if free space allows, and there are interruptions in the water supply from city networks, then a non-pressure storage tank with a float valve will not hurt either - the pumping station will draw water from it. This scheme has already been mentioned above.
The optimal solution - the pumping station takes water from a volumetric non-pressure storage tank
Since a pumping station is usually installed to ensure the operation of the entire water supply network of a frequent house or apartment, when choosing a model, it is necessary to pay special attention to the pressure it creates and to its performance. It will be of little use if, taking into account the height and remoteness of the draw-off points in the farthest section, the pressure is insufficient. In the practice of private households, this can be, for example, a garden tap through which watering is done. personal plot. Therefore, when choosing, you should focus on the most distant points in height and length. If these are just mixers, then they will have enough pressure of 10 ÷ 15 meters (1 ÷ 1.5 bar). In the case of installing equipment that requires special pressure parameters, they are taken as the basis.

Device and principle of operation

Water pressure booster - pumping equipment designed to create a reliable water supply system. As a rule, such equipment includes: a group of identical pumps, supply and pressure manifolds, a storage hydraulic tank, an automatic control cabinet, pipeline accessories(valves, gate valves, etc.), as well as pressure sensors and dial gauges. The main task of the installation is the implementation of the inherent algorithm for maintaining pressure in the pressure manifold, which ensures maximum efficiency. There are also hybrid water supply and fire extinguishing installations, they combine these two work functions.

All manufactured pumping stations and installations are capable of solving water supply problems of any complexity and volume.

Fire fighting pumping stations

Device and principle of operation

The equipment is used in fire extinguishing systems to eliminate fires. The operation algorithm of fire extinguishing installations and stations is based on the principle of starting the main pumps or a jockey pump (a pump with a low capacity to compensate for leaks) under the condition of a pressure drop in the pressure (fire) pipeline and (or) a signal from the control unit. If in the fire extinguishing mode the pressure in the controlled pipeline exceeds the set value, the pump stops. In the event of a subsequent drop in pressure, the pump will restart. When a jockey pump is used in the system and if the pressure drops below a certain level and for a given period of time it could not compensate for the drop, then the main pumps are switched on.

The Anmeks company manufactures at its production site and supplies throughout Russia high-tech pressure boosting units of the NAPOR series for various purposes and designs, made on the basis of modern components of Russian and foreign production.

In our pressure boosting stations, we combine both European components, for example, pumps from international concerns that have proven themselves in Russian realities: LEO, KSB, Grundfos, Wilo, Lowara, DAB, Flygt, and our own developments: a modern logic controller of the SLK-1 series, graphic operator panels for serial production, power supplies, phase control relays, control cabinets of the KLASS series for control and protection of pumping units, and others interesting solutions, allowing to ensure high quality, reliability and maintainability of the units produced.

Pumping stations are widely used at construction sites, in residential buildings, at various industries food and chemical industry, private houses and cottages, systems of heating, circulation, watering and melioration. In a word, where it is necessary to provide the required flow and pressure, pressure boosting stations "NAPOR" are used.

In addition, urban areas for building are constantly decreasing, forcing construction companies increase the number of storeys of houses, and urban water supply cannot provide adequate pressure in the cold water and hot water systems at such a height of buildings. Monoblock stations that are completely ready for connection to networks help to solve the problem.

Structurally, the NAPOR pressure booster units are divided into the following subgroups according to the type of pumps used:

Horizontal multistage pumps type CM, MHI
Vertical multistage pumps type CR, MVI, Helyx, Movitec
Horizontal single stage pumps type NB, BL, Etabloc
Vertical single-stage pumps type TP, IL, IPL, Etaline, Etaline-R

All of the above allows us to say with confidence that using the equipment of our production, you as a customer receive technically competent solutions (optimal in terms of price, quality and delivery time) that will help you bring water supply to a qualitatively new level when implementing your facilities.

Plumbing - part engineering networks private houses and apartments. Due to the weak pressure in the pipes, residents often receive an insufficient amount of water. This situation limits the possibility of using two plumbing points at the same time, and washing and Dishwasher just don't turn on. The only way to make a difference is with a pumping station designed to increase water pressure. The power and performance of the installation is selected individually. The compact device is able to normalize the level of pressure and maintain an optimal indicator.

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

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

Classification of pumping equipment

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

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

The pump motor is cooled in two ways:

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

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

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

Equipment design includes:

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

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

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

How to choose the right unit

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

Productivity - the amount of water that the installation pumps per unit of time (minute, hour).
Power - is selected based on the number of consumers. A high score is not always a plus. The station sucks water from a source (well, pipeline), if the pump runs faster than it is being filled, then the unit may be left without liquid and overheat.
Compliance of the model with the cross section of pipes in an apartment or a private house.
Maximum lifting height. This indicator is important for the use of equipment for autonomous water intake of a private house and for pumping water to the upper floors of an apartment building.
Unit size. The dimensions of the station, including the accumulator, must correspond to the area of \u200b\u200bthe room where it will be installed.
Noise level. This criterion depends on the method of cooling, " wet rotor” runs silently, and the “dry rotor” is noisy due to fan blades.
Range allowable temperatures. Devices can be for hot, cold water or universal.
Installation type - vertical or horizontal, the choice depends on the characteristics of the room.
Manufacturer's reputation. Products of unknown companies are distinguished by an attractive price, but their quality is doubtful, and service centres missing. It is better to buy high-quality and reliable equipment from a manufacturer with positive reviews.

Notable hardware manufacturers

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

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

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

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

Mounting the booster pump

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

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

DIY station

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

The control system should include:

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

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

Tips for choosing and installing a mini pumping station

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