The quality indicator of the water supply system, both a centralized highway and autonomous, is the pressure indicator. For its measurement, specialized pressure is applied (mainly to adjust the pressure when connecting home appliances - washing or dishwasher, boiler, gas GVS or in the heating system).

Sometimes the pressure is so weak that everything is clear without using the instruments. Correct the situation will help increase pressure in the system when connected.

Features of use

Pumps to increase water pressure in an apartment or a private house - a special category of pumping equipment. The Systems of the HPW and GVS consist of a network of pipelines, the free movement of water by which is determined by the level of pressure in the system.

According to the standards adopted in Europe, this indicator should be from 2.5 to 4 atmospheres, depending on the length of the system and the average daily load on it. The intensity of the pressure affects the number and type of equipment used. For example, pressing enough pressure from 2.5 atmospheres. And to connect a shower cabin, jacuzzi or heating systems - 3.5-4 atmospheres.

Water pressure in the apartment is usually equal to 3.5-4 atmospheres. But this does not mean that from more comfortable conditions for life will have to abandon. An efficient and inexpensive solution is to increase pressure pumps for water in apartments. With the development of multi-storey construction, cases occur when water does not go to the consumer in view of too much the length of the riser and the pumping station used in the pipeline is not capable of raising water to the required level. In this case, an alternative to the pump will be in the apartment.

The same situation in the country and cottage buildings. In them, the water supply system is often autonomous, and one, even characterized by increased power, the pump does not always provide due intensity of the stream. It will not pump water with due efficiency and in the event that errors were allowed when designing or laying the system.

A water pump that increases pressure is also applied in industry. These are large backup type models that allow not to stop production processes in the event of an emergency disconnection of the system or reducing the water level in the water supply.

Device, principle of work

As a rule, an increase in pressure pump for water, including consumer for the apartment, turns on automatically when fixing a critical low pressure level. They differ in the type of design and appointment.

Views and differences

By key operational and production parameters, the water pressure increase pump is divided into 2 main categories:

• circulation pumps to increase water pressure in the apartment;
• self-priming pumping stations.

The most popular in view of a universal simple design is considered a circulation pump for water pressure increase, the pump to increase the water pressure of this type is easy to install and provides optimal indicators of the intensity of motion inside the system. It is characterized by compactness and is intended mainly to adjust the performance of heating systems and.

The unit consists of a compact engine, which leads to a motion equipped with a rotor. By injection of water circulation rate, pressure lifted throughout the system. The market shows models and cold water, and for hot. Pumps of the first type of cheap due to use in the process of producing durable, but inexpensive plastic. They can operate in a temperature environment not exceeding +40 o C.

The second variety of pumping equipment - the station is more complex and productive. The key difference from circulating equipment, which is crashed in any fragment of the network and does not affect its autonomy performance, the pumping station completely cuts off the system from an external source of feeding. However, it is this installation that allows you to increase the water pressure to the required level.

The design consists of a surface pump operating from the hydroaccumulator equipped with a self-priming mechanism. Such an aggregate is guaranteed to improve the quality of water supply, even if, for technical reasons, water is not available on the upper floors of the building. The pressure level is adjustable and maintained on the specified parameters for adjusting the relay level using the membrane-valve system.

Main characteristics

When choosing a model, we recommend paying attention to the information provided by the manufacturer, since not all units are universal. In general, to select a pump or pumping station, it suffices to pay attention to the following characteristics:

• type of Sun system - hot or cold;
• the power of the device determined by the water intake ability, the height of water lifting and the maximum value of the pressure increase;
• pressure and consumption;
• temperature Range;
• power consumption parameters;
• productivity (the amount of pulmoned mass per unit time);
• the direction of the axis, which moves the workers;
• startup type (mechanical or automatic);
• motor cooling method;
• the level of generated noise;
• material production of the body and nodal connections.

Famous manufacturers

The corresponding segment of the market is extensive - it presents equipment from both domestic and foreign manufacturers.

The leader is products, in particular, 15-90 / UPA15-90N. The advantages include low weight and envelope, simplicity of connection to the pipeline. With relatively low power from increasing the pressure level by 1.5-2 atmospheres, produced from high-quality durable materials (accordingly cast iron and stainless steel) and almost do not create noise. Both installations are equipped with a switch that allows you to adjust the working parameters using manual or automatic settings.

The German brand Wilo produces pumps equipped with a duct sensor, mainly with a wet rotor cooling type. Popular models - PB 088-EA, PB-H 089 EA, PB 201-EA and PB 400-EA in cast iron housing. The advantages of this brand include:

• simple installation due to fastening with nuts;
• thermal protection of the motor;
• small power consumption;
• compactness;
• low noise;
• corrosion resistance.

Chinese Wester WPA 15-90 / 20-120 pumps have proven to be reliable technique in the available segment. It is possible to apply them in equipping apartments, country houses and cottages. Each of the models operates in one of the three provided modes in the temperature range + 6 ... + 60 ° C, has a slight consumption and raises water to a height of up to 9 m.

Connection rules

Installing the pump for increasing pressure is simple - it is possible to cope with it without attracting specialists. It is more efficient to carry out the cut at the entrance.

Installation of a circular pump:

• the product is crashed in a single position according to information from the manufacturer;
• getting Started, make sure that the water supply system is disabled, there is no water in it;
• cut the pipes, connect and fix the pump, process the joints with moisture-resistant and heat-resistant sealant;
• connect the unit to the power grid;
• test the installed pump.

Pumping stations are also cut into the system, but this process is better to entrust specialists. The complexity of the installation is that in addition to the insertion and connecting the pump, it must be properly assembled and tested the input / output hoses. The time consuming and requires practical experience is the process of setting the pumping station.

Installation in the apartment pump that increases water pressure GPD 15-9A (video)

If you are tired of a weak water head in the crane, and you want to solve this problem, then you can immediately offer the installation of the pump to increase the water pressure. It can be said that this is the easiest solution, however, not in all cases it is possible. For example, what if in your city or microdistrict on schedule turn off the water? The pump will not fully solve the problem of water shortage. In this case, it becomes necessary to create an additional source of water. Or at least, then the equipment should be purchased for the backup storage of a small volume of water.

If you all decide and in your case the installation of the pump is an ideal solution, it is important to familiarize yourself with all the selections of choosing this device. However, first of all, it is necessary to deal with the causes of low pressure. Although the main direction of this article is the choice of pump, we are comprehensively and wider consider with you and this question. In particular, we will deal with what optimal pressure should be in the crane for the normal exploitation of household appliances (washing, dishwasher), convenience of using plumbing devices and so on.

Water pressure - what it should be

In general, the pressure is measured in the atmospheres or bars. So, 1 bar is 0.99 atmospheres. If we are talking about apartments in multi-storey private houses, there are norms that regulate the level of pressure on the entrances to the house and the entrance to each apartment. These regulations are described in SNiP 2.04.02-84 and SNIV \u200b\u200b2.04.01-85.

The table holds pressure indicators on different sites, as well as in the apartment and house:

For home water pipes and satisfying everyday needs, 2 atm pressure is quite enough. However, there are exceptions. For the shower cabin with the hydromassage function, as well as for the bathroom with a jacuzzi, pressure is needed up to 4 atm.

Some may believe that the more pressure will be in the system, the better. But there is also the reverse side of the medal. With too high pressure, for example, from 6.5 atm and more, may not withstand fittings on pipes and other connections. Also, cranes, mixers and other plumbing equipment can be found.

How to determine water pressure

Given the data given above, it is important to be able to determine the pressure of water at home. This task is simplified if the measuring equipment is already standing at the entrance of the water supply system - a pressure gauge, as can be seen in the photo:

However, as practice shows, rarely has such equipment. For this reason, in this section, we offer you several methods, how to determine the level of water pressure.

Stationary pressure gauge - optimal solution

If you are installing or replacing the pipeline, then you can install a stationary pressure gauge for measuring water pressure in the system. In this case, you will not need to resort to submitumed means.

Ideal if the pressure gauge is installed near each plumbing device. However, from aesthetic point of view, this is a clear minus. Plus, it is quite a timely pleasure.

If you follow the practice, the pressure gauge is installed immediately at the entrance to the apartment. At the same time to the meter. Why? Everything is very simple: the filter, the check valve and the meter itself is already knocked down the pressure. Therefore, if you are interested in the indicator directly at the entrance, then the pressure gauge is installed in this way.

But remember, on all consumers the pressure will be different, as it falls, passing through many barriers in the pipeline. The following elements affect the decrease in water pressure:

• places with a change in pipe diameter;
• installation of regulating and shut-off reinforcement;
• filters;
• tees;
• turns;
• hoses (on a toilet bowl, in the shower and other).

Given all this, the water pressure indicator at the entrance to the apartment and at the exit of a particular consumer will be different. If you do not have a pressure gauge at all, then below we present for you 2 measurement methods for which you will need a portable pressure gauge and hose.

Video: Operation of stationary pressure gauges

Pressure gauge for testing for testing

One of the simple methods for measuring pressure - instead of the shower watering can be installed a pressure gauge. To do this, you will need to prepare the following:

• thread extension;
• water gauge for water up to 6 atm;
• adapter on the thread ½;
• fUM tape.

All these elements should be connected to each other. To do this, the metal extension can be screwed to the pressure gauge, and after the transition to ½ threads. Fum-ribbon is used to seal the threads. It is important to make a hermetic connection, otherwise it will not work accurate measurements.

After that, in the shower cabin, we unscrew the watering can and instead we screw our design with a manometer. At the same time, it is important to be careful that a sealing gum will not be lost in the nut from under the watering can be lost, it looks like this:

Now you can open the crane and measure the water pressure. At the same time, it is important to produce one operation: so that there is no air in the shower, switch the water from the shower to the crane several times. The air will be released, and you can find out the pressure value.

But here you should not hurry with conclusions. The fact is that the water enters the shower along the complex system of pipelines. Moreover, it is known that the more turns the water and thinner the pipe (the diameter of the hose is much smaller than the diameter of the inlet pipe in the apartment), the stronger the pressure drops. Therefore, in this way you can only find out the pressure indicator on this plumbing device. If this operation produce, for example, near the washing machine, the indicator will be slightly different, as the hose diameter is greater than that of the shower.

This method is convenient because it is possible to determine the presence of a blockage in the pipe. For example, you noticed that the water pressure is good in the bathroom, and in the kitchen is relatively low. By installing the pressure gauge and comparing the indicators, it is easy to determine which plot formed on the pipeline on the pipeline.

Immediately before disconnecting the shower watering can from the hose or dismantle a different plumbing device, do not forget to turn off the water. Otherwise, you can not avail floodings.

Video: homemade pressure gauge for pressure

Using a hose for computing pressure

If not accurate, then approximate pressure measurements can be made using a conventional 2 meters long hose. This method is primarily used only to measure the pressure at the outlet of the water from the crane.

An important condition is the use of a transparent hose. This will allow the necessary measurements.

The measurement process occurs as follows:

Having all measurements, some computations should be made by the formula:

P \u003d RATM × H0 ÷ H1.

In this formula:

• P - pressure in the pipeline at the exit of the crane, measured in atm;
• RATM - the pressure in the hose until the opening of the crane is measured in the atmosphere;
• H0 - the length of the hose before the start of tests from the zero level;
• H1 - the length of the hose between the cork and the well-established water level.

But remember that such calculations will be close to reality, or rather, measuring the pressure can be methods described above.

Causes of low water pressure in plumbing

Before making any actions, it is important to determine the cause of low pressure. In some cases, the purchase and installation of pumping equipment will not fully solve the problem. Causes can be a variety of:

• water leakage on the waterway track;
• unestation of the inner diameter of pipes;
• water purification filter clogged;
• faulty faucet or other locking valves.

Often, the cause of low pressure is poor-quality maintenance by water supplier. For example, utilities deliberately can turn off the work of one or more pumps in order to save. As a result, the consumer gets water, however, its pressure leaves much to be desired.

Notable is the fact that according to the situation of SNIPA No. 2.04.02 of 1984, as well as the state decree No. 307 of 2006, the minimum water pressure pressure for a single-storey building is 1 atm. If in the house 2 floor, then 2.4 atm.

Now consider several methods, how to increase water pressure, as well as look at the option with the installation of pumping equipment.

Video: Causes of low water pressure in the pipeline

In this video, it is described that water pressure may be low due to the clogged aerator:

Here you will learn that water pressure may fall due to a clogged filter intended for rough cleaning:

And here it is described about why a weak pressure may be due to the check valve:

How to increase pressure

It would be absurd about the installation of the pump, this is an absolute panacea. This option is possible only in one case - when water in the pipeline is uninterrupted. With constant water disconnections, if it comes to the city highway, the operation of the pump is frowning can lead to his breakdown. If there is no water, then the pump is simply overheated, and the engine burns. Water is a natural cooler. However, there is a way out here - installing special automation, for example:

• relay to protect against dry stroke;
• water level sensor;
• water flow control.

This equipment is intended for the pump to be disconnected in the absence of water. As a result, the pump will be completely protected from possible breakdowns.

Video: Protection of the pump from dry stroke

If you live in an apartment building, installing a pump to increase the pressure significantly worsens the quality of water supply from your neighbors. To prevent this, you can take some measures. At the same time, solutions for the apartment and private house should be different. Why? Now make sure of this.

Nuances set pumping station

In this case, the mandatory component of the link is a centrifugal pump of self-priming type. This equipment will allow even a zero pressure level to raise water from a certain depth of the input. This will provide sufficient water pressure.

Additionally, such a station is equipped with a pressure relay. Due to this, when the pressure drops in the pipeline, the pump will automatically turn off / turn on. Plus, a water supply under sufficient pressure will be created in the accumulating tank. It is consumed only in cases where it will be observed in the highway. As a result, this installation provides a small margin of water and the necessary pressure. But this method is relevant only for private houses.

Consider such an example: as you know, on the last floors of the house, residents most often experience the problem of water shortages. If they begin to solve it aforementioned way, it is soon in the whole house, at least, the tenants will begin the struggle for the water stream. As a result, this can end for you fines from public utilities. After all, the installation of pumping equipment without appropriate permits is prohibited. Plus to everything, the pump installation will cause an imbalance in the entire highway. Also keep in mind that self-priming pumps have technical limitations. They are able to raise water to a height of about 8 meters. So, if you live on the third floor, it will work with the stretch, not to mention the floors located above.

Video: Installation and launch of the pumping station

Reserve water supply installation - how to implement

This system is most effective in cases where you turn off the water over time. The installed tank is filled with cold water. The entire subsequent water consumption will be carried out exactly from it. It is equipped with a pump and other equipment. Due to this, sufficient water pressure in the whole house or apartment is ensured. Plus, the problem of turning off the water is solved, you will have a clock day. It will not be only if the electricity is turned off.

Installation of backup water supply is easier to implement in a private house. In the apartment it is enough to distinguish the place to set the backup container. Is that you have a lot of rooms, and one can allocate for such needs, or you live on the top floor and the container can be installed in the attic. Such a solution will not cause an imbalance in a plumbing riser.

To implement the project, it is necessary to choose a suitable container. Most often, a plastic tank is used for this. Today you can find models of different litters. The choice of tank volume will depend on the estimated consumption of water in your family. For a family of 3-4 people, there is enough capacity to 500 liters.

Video: Reserve water supply in the apartment

Place to install a tank

For apartments, a suitable location can be a balcony / loggia, storage room, bathroom and other rooms, where there will be free access to it. If you live on the last or penultimate floor, that is, it makes sense to consider the option with installing a tank in the attic. However, in this case, the container must be carefully insulated and worry about safety measures so that it is not stolen.

If the backup barrel and pumping equipment is installed inside the apartment, then it is important that the pump be silent. Otherwise, it will annoy you and create discomfort to your neighbors.

As for the private house, everything is much easier here. The selected location can be a basement or other technical room. The main condition so that it is heated.

Installation of cumulative tank

So, in addition to the cumulative tank, you need to purchase a pump, preferably silent. In this category, you can find equipment such brands:

• Grundfos MQ;
• Rens;
• Pedrollo 3 cpm and the like.

It is also necessary to install automation that necessarily includes the pump protection relay from dry stroke. This relay will serve a signal to turn on / off. Thus, the pumping equipment will be protected from breakage.

So that the pump does not turn on with the minimum water flow, the system can be equipped with a hydroaccumulator. Its volume will directly affect the frequency of switching on / off pump.

So, the entire diagram of the backup cumulative tank will work for this principle: as soon as the water turns on in the crane or mixer, the pump is turned on and sufficient pressure issues. If the water supply capacity is exhausted, the relay gives a signal to disconnect the pump. As a result, the work of the entire system will be safe and economical.

Video: Installation features and assembly of cumulative capacity

As for the barrel, it is necessary to equip it with a float. As soon as it is filled, the float overlaps the water supply. The system completely resembles the principle of the drain tank on the toilet. Also mounted with a coarse water purification filter. It is mounted at the entrance of the highway to the house, as well as before the pump. Due to this, no compounds will penetrate the cumulative tank, as well as in the pump, which can bring it out of order.

You can install an additional filtering system, it is already at will. But consider the presence of filters will slightly reduce the pressure.

Also, the water reserve drive system is equipped with shut-off reinforcement, check valves, necessary fittings and other components. You can figure out more in detail in the connection, seeing the schemes presented in the article.

Schemes: Connecting water reserve tank

Pumping station for all risers

Another option that allows you to increase water pressure in the apartment, this is an installation in the basement of a powerful pumping station, a large storage tank and a hydroaccumulator. In this case, all over the riser in the entrance is supported by the required pressure, and the water will be the clock. Although this output seems to be an optimal solution, it is extremely difficult to implement it. Not all your neighbors agree to produce such large-scale work, due to financial considerations. And some, for example, the elderly, and such a water pressure in the crane is enough.

Principle of action protection of the relay of dry stroke

The relay is designed to control the water pressure in the system. If the pressure drops below the specified mark, the relay is triggered and the power circuit is broken. The pump is turned off and thereby protects against dry stroke. One of the main elements of the relay - membrane. It directly reacts to the contact group and pressure. If the water pressure decreases, the membrane presses on the contact group, disconnecting the power.

Based on the factory settings, the relay can react to the pressure in the range from 0.1 to 0.6 atm. With this pressure, the relay is triggered and eliminates the dry pump.

Video: dry running relay

Relay and hydroaccumulator: Is it possible to combine into one system

If you use a hydroaccumulator in your system, the relay will not provide a pump 100% protection against dry stroke. This feature of this system is explained. The relay is installed in front of the hydroaccumulator and pressure switch. Between protection and pump usually worth the check valve. As a result, the membrane inside the relay is always under pressure, which is created by the hydroaccumulator.

For clarity, let's see the following situation: there is a small supply of water in the hydroaccumulator, while it does not have it in the well / reserve capacity. Moreover, the lower pressure threshold is usually installed in the area of \u200b\u200b1.4-1.6 atm, the membrane in the relay will not work, since in fact there is pressure in the system. This will lead to the fact that the pump will start working in dry. POMP will turn off only in two cases: when water is spent from the hydroaccumulator, or when the pump burns. If this happens when there is a water supply in the system, then no threat carries it. Another thing is when this happens in the absence of feeding. For example, the tank was merged at night, the hands were waved, the tank scored water. In this case, the pump, naturally, is turned on, but there is no signal to shut down. In the morning the pump is most likely half ancient.

Given this if the system is equipped with a hydroaccumulator, it is preferable to use other devices for protection against dry stroke.

Video: Why do you need a hydroaccumulator how to connect it and calculate

From this video, you will be able to learn how role the hydroaccumulator performs:

This plot describes the principle of action of the hydroaccumulator:

And from this video you can learn how to calculate the container of the hydroaccumulator:

Water Level Sensor - Alternative Dry Rift Relay

Such sensors are mounted in reserve containers, as well as in the case of the use of wells / well. In our case, consider the float sensor, although there is its analog - electronic.

The float sensor is two types:

1. On emptying (this sensor prevents dry pump stroke).
2. On filling (this sensor prevents water overflow).

In our case, the sensor for emptying is just a suitable option to completely eliminate the dry pump:

The principle of operation is simple: in the presence of fluid in the capacitance, the float sensor is at the top, when lowering the level, so that the electrical circuit is disconnected, the sensor is lowered. As a result, the pump will be completely disabled. It will not be turned on until the level is restored to the desired indicator, and the sensor will again give a signal to switch on.

To prevent the pump to prevent the pump, the cable of the float is connected to the gap of the phase wire.

Water pressure relay to control the pump operation

Pressure relay consists of two elements: one hydraulic, other electric. The hydraulic part has a membrane. It presses two springs (small and large). Due to this, the signal is sent to switch on / off. As for the electrical part, there is a group of contacts that closed / open the electrical circuit, look in more detail in the diagram:

It is worth noting that the relay is produced in two types:

• electronic;
• mechanical.

Given that the mechanical relay is cheaper, it is more often used in the arrangement of water supply systems.

Pressure Relay Connection Scheme

Stripping from its structure, it becomes clear that the connection occurs in two stages, at the beginning to the electrical part, then to the water supply. This device does not need to move, for this reason its installation is carried out stationary. Consider how to connect to the electrical part and to the water supply.

We connect the electrical part

It is optional, but it is better to organize a separate electrical line for a pressure switch, so more likely that it will last longer. For this, the wire is supplied to the electric tailor, and the individual RCO is mounted.

When the pressure relay is connected, grounding is required. This is explained by the fact that water and electricity are combined in this device, which is already unsafe.

Inside the relay there are 3 pairs of contacts, each of which has its purpose:

1. Ground.
2. To connect zero and phase wire from the control panel.
3. For wires from the pump.

Connection is carried out according to the scheme from the manufacturer.

Connect to the water pipeline

The easiest and most affordable method of connecting the pressure switch to the water supply is the installation of a special adapter on which there are necessary outputs. For this purpose, a positive fitting is used, see the connection scheme:

It is connected to this stacker: a pressure gauge, a hydroaccumulator, pump, access to the water supply network inside the house and the pressure relay itself. Due to the manometer, it will be much easier to monitor the pressure in the system and adjust the relay.

This connection scheme has its advantages. Water to the house will arrive, bypassing the hydroaccumulator. First, the water will go into the cranes, and only then the tank will fill.

Video: Pressure Relay Connection

Relay adjustment

The adjustment process will look at the example of the RDM-5 pressure relay model:

It is possible to implement individual settings for one or another water supply system. As a rule, the new (factory) relay has standard settings, it has a minimum pressure threshold of 1.5 atm, and the maximum threshold is 2.9 atm. If necessary, these indicators can be reinstalled independently.

As we have talked above, the relay has two springs - small and large. So, adjustment is carried out by twisting nuts on the springs. If the nuts weaken, the pressure drops, if tighten, the pressure increases. One turnover of the nut on average equals 0.6-0.8 atm. For this reason, you should not twist them very much.

Classification of pumps to increase water pressure

Specifications are allocated for which pumps are distinguished:

• mode of operation;
• cooling principle;
• application.

Pump and pumping station: Benefits and Disadvantages

The pump and pumping station have their own characteristics that are marked in the table:

Pumping station: work principle

As for the pumping station for increasing pressure, it takes a lot of effort to introduce it. However, the result to increase water pressure in the pipeline will be impressive. So, for its introduction, additional equipment will be required:

• relay to control the system;
• centrifugal pump;
• hydroaccumulator.

When using it, the consumer uses water that accumulates in the hydroaccumulator. Its use completely eliminates the likelihood of pressure jumps. You can use water, even if the water supply is stopped. The operation of the pump station is regulated by the relay. If the pressure drops, the pump is turned off.

Types of pumping stations

All pumping stations are divided into 2 types:

• ejector with remote or built-in ejector;
• non-comer.

As for the ejector, they are equipped with an inkjet centrifugal pump (self-priming). Models with built-in ejector are less sensitive to the presence of air in the system and provide high water pressure. Minus is the inability to raise water from great depth and strong noise when working.

To raise water from a depth of 20 or more meters, a station with a remote ejector will be required. This pumping station can be set at a remote distance from the well to 40 m. If we talk about disadvantages, then it is a high sensitivity to dirty water and the presence of air in the system.

As for non-certified pumps, a special multi-stage design is applied to supply water. Her work is almost silent. Such a pump consumes less electricity. However, the depth of suction is not more than 9 meters.

Pumping stations are divided by the type of tank used:

• Cumulative. The tank is mounted separately from the station, attached under the ceiling, installed in the attic and the like. Such a drive is practically not used today, as it has a lot of weight, represents the risk of flooding and does not provide sufficient pressure.
• Diaphragm tank. The container is mounted in the basement, since the water level is adjusted by the battery. The tank has a small size. Mostly used for shallow wells.

In addition, pumping stations are divided into water source:

• Deep. The presence of a reliable housing. The device can be completely immersed in water.
• Digging. The ejector is placed on top, and the hose is lowered into the water. However, such a pump can be used when there is no deeper than 9 meters.

What to pay attention to when choosing a device

If you have already come to buy a pump to increase the pressure, it is important to pay attention to several important parameters:

• cross section of pipe diameter;
• maximum power and output pressure;
• performance;
• which level of noise is issued when working;
• for which systems of the water supply system you can use hot / cold water;

Be sure to take into account the fact that the pump you bought on average is able to increase water pressure up to 4 atm and up to 40%. Therefore, their use is possible under conditions of constant water pressure in the pipeline equal to 1.5 atm.

Among other things, you should determine the quality of your wiring. Often, a new installed pump is not capable of issuing the necessary pressure due to the weak voltage. Therefore, it may be necessary to carry out an individual line.

Important specifications

The table below presents some specifications to which you must pay attention to when choosing a pump:

Models of the raising pump

Now consider the models and features of various water pumps that can be used to increase the pressure. It is also worth noting that in each individual region of our country, prices may differ slightly:

Video: Features of the raising pumps

Independent installation of a pump that increases pressure

The pumping technology for increasing pressure is practically no different from the installation of a conventional circulation pump. The work process consists of several consecutive stages:

1. Choosing a suitable pump and a hydroaccumulator.
2. Installation of the hydroaccumulator.
3. Installation of pipes for connecting.
4. Fasteners of the pump.
5. Pump and hydroaccumulator binding.

A similar set of pump, in fact, resembles the usual pumping station.

So work happens in this order:

• First of all, fasten the household pump in the selected place, some pump models need to be mounted only horizontally, so be sure to take into account this parameter.
• Install the hydroaccumulator.
• Considering that the pump is mounted on the supply of water supply, then immediately when entering the house, the check valve is mounted.
• Already after the line, the pump is connected to increase pressure.
• Next is connected by the Cross, in the direction of the pump, the check valve is also mounted.
• The remaining 3 exits on the crosses will be directed to the hydroaccumulator, the pump control relays and towards the sources of water.
• All electrical connections must be as sealed as possible.
• This system can be equipped with a stationary pressure gauge for measuring water pressure in the system.
• An individual RCO is installed on the control system (relay).

The principle of such a connection is based on the scheme, which is provided below:

It is important to take into account some nuances if you are working in a private apartment. A crane must be installed on entering. Immediately before starting work, it should be blocked. When installing the pumping pump, do not confuse the direction of the arrows to be directed away from the feed.

All connections should be as sealed as possible, which will avoid water leakage and pressure. Therefore, carefully pack each joint. Other details of the installation work can be found in the offering video material to this article. You will learn how to install pumping equipment with automation yourself.

So, we reviewed with you the question of increasing the pressure in the water pipe system from different sides. Of course, it is impossible to describe all situations. If you have other experience in this area or remembered other nuances of work, then be sure to write comments on this article.

The housewater system is a rather complicated design designed to provide high-quality water supply. The performance indicator of the entire water supply system is characterized by a single indicator - water pressure. Pumps to increase water pressure in a private house Assist to set pressure indicators that are necessary for the convenient use of household appliances.

Why do you need pumps to increase pressure

According to regulatory documentation, the pressure in plumbing communications must correspond to the parameters of 3-6 atm. As practice shows under the pressure of less than 2 atm., Operation of technology (dishwasher, washing machine and water heaters) stops.

The quality operation of various household appliances, as well as fire hydrants, is possible only with the level of water pressure at least 2 atm. In cases where this indicator does not correspond to the norm, special devices designed to help provide the necessary pressure in the pipes.

These technical devices include:
1. Pump to increase pressure.
2. Pump station.

Consider in more detail the principle of pump operation to increase water pressure. This device is used in the case when there is water in the plumbing system, but the pressure level is so small that the quality of the water supply is simply impossible. In practice, such a problem is quite common in high-rise buildings, where the inhabitants of the last floors due to the fact that in the water supply system, very low pressure is often sitting without water. A good output from such an unpleasant situation can be the installation of the pump to increase the pressure level.

Before installing this device, you should carefully study the problem and identify the causes of weak pressure. These include corrosive damage to the inner surface of the pipes or tubes from organic sediments, which appear due to improper care of the water supply system and the poor quality of the supplied water. With such problems, the use of the pump is not fully justified as, by eliminating the problems, the pressure very quickly comes to normal.

Depending on the destination These devices are divided into:
- operated with a certain form of water (cold or hot)
- Universal.
Depending on the cooling method Pumps are divided into:
- Dry rotor. Cooling occurs due to a blowing fan, which is mounted on the shaft.
- Wet rotor. Cooling occurs due to fluid pumping with an impeller, which together with the rotor is omitted into the water.

Options Operations Pump helps to divide the devices to the following types:
- Manual mode pump. The device works constantly. Adjusting work only manually. It is very important using this device to avoid overheating;

What are the advantages of using high pressure pump

1. Regarding compact dimensions.
2. Small weight.
3. Silent motor operation.
4. Installation of the device is carried out directly on the pipes of the plumbing system.
5. Low cost.

What you need to pay attention to, choosing a high pressure pump

You can buy a high-quality device in stores, outlets in building markets or on the Internet. All detailed information about the pump can be easily found at the seller if you want to install it.

Pumping station

However, making a purchase, you should still pay attention to the following technical indicators:

• efficiency of the device;
• power and pressure;
• noise level in work;
• running the working temperatures.

Of course, the higher the data will be the indicators, the greater efficiency of the device can be said. Do not forget about the pricing policy. As a rule, the cost largely depends on the manufacturer's brand, manufacturing materials, technical parameters of the device. Choose a pump to increase pressure, taking into account the features of plumbing communications in your area.

If the apartment has a fairly low water pressure, then you can purchase an increase in the apartment pump. Small head problems can deliver inconvenience to residents, and also negatively affect the work of household equipment. Because of the small pressure, boilers, dishwasher and washing machines can stop functioning. If you encountered a similar problem, that is, it makes sense to think about the acquisition of the described equipment.

Definition of the task and choice of equipment

If you need for an apartment, it is originally necessary to decide what nature is the problem. It may be low pressure, as well as its frequent differences. If there is no pressure on the last floors of the multi-storey building, then, most likely, you will have to purchase a station.

Main parameters when choosing equipment

Initially, it is necessary to determine the task that will be put before the pump. It can adjust, reduce or increase pressure. In the next step, you must determine what characteristics the device must have. You can not choose the device without information about the size of the service area. Thus, it is important to know what the size of the room, where the pump will be located.

Compact solution

The increase in the apartment pump can be used for a slight increase in pressure in the system. Such a need may occur when an increase in pressure per 1.5 atmosphere is required. At the same time, the installation of compact equipment will be quite enough. This device is installed directly into the tap pipe. Connecting such an aggregate is made before the point of fixing pipes, as well as near household appliances. The selection of the device will depend on the need to enhance a small pressure. If there is a need to raise water from the bottom up, then experts recommend choosing a hydraulic accumulator.

Choose a pump for work modes

The increase in the apartment pump can work in one of the two modes. Depending on this, you can choose the desired model. Different equipment options have manual or automatic. In order to prevent overheating during work, if the pump involves manual control, there is a need to constantly monitor the indicators and turn off the equipment in a timely manner. If you do not comply with these rules, the unit can overheat, and subsequently will fail at all. The increase in water pump in the apartment can work in automatic mode. In this case, the process regulation occurs by means of sensors in the ducts. The inclusion of equipment occurs at the moment when the water tap is open. If the water is not poured, the pump will be at rest. Experts advise you to choose such varieties of equipment, as it is much more convenient compared to the manual species. The aggregates are supplied with special treads that exclude the likelihood of inclusion at the moment when water does not flow. This saves and guarantees the durability of the device.

Choosing a pump by cooling method

The increase in water pump in the apartment can be cooled in different ways. Among other methods, you can select the engine impeller, which is the blades on the shaft. They are cooled. This mechanism, equipped with a dry rotor, allows the equipment to work silently and helps to increase the efficiency. A pump that increases pressure in the water supply can be cooled due to fluid that is pumped during operation. The mechanism that is equipped with a wet rotor almost does not create noise, especially if you compare with the previous option.

When it is worth choosing a pumping station

Before purchasing a pump that increases the pressure in the plumbing, it is necessary to ask if the problem is low pressure, and not damage to the pipe. The fact is that over the years, the pipes from the inside are coated with a raid and mechanical particles that remain after filtration. Their volume increases, which causes the low bandwidth of the system. If the reason is this, then how modern and effective will not be able to solve the problem. In this case, it will be necessary to replace the entire water supply system. However, if the problem is still low pressure, then you can prefer a pumping station that has a higher power compared to a conventional pump. With her, it will be possible to raise water even from the lowest tiers of the house. The station involves the presence of a centrifugal structure, which is connected to the hydroaccumulator relay. In the process of operation, the liquid is pumped from the system, entering the accumulative tank. This option is suitable in cases where the water turns off quite often. In this case, you can use stored in water. When the water is turned off, the pressure will decrease with time until it reaches a certain mark. After the relay reaches the specified level, the relay will automatically work and contributes to the inclusion of the pump. If you decide to purchase a pumping station, you will need to think about how much its capacity should have the more location, the longer the pump will last and the less it will turn on and off.

Why it is worth choosing a water-cooled pump for apartments

If you are considering boiling water pumps, you should think what kind of choose for your home. Specialists are most often advised to acquire models that work at the expense of water cooling. This recommendation is due to the fact that the small pump will simply fix it to the plumbing pipe, among other things, to produce such work you can independently. As an additional positive feature of such pumps, a wet rotor protrudes, which provides silent operation. Therefore, it can be installed anywhere in the apartment, without fear that the equipment will cause discomfort. The installation of a water-cooled increases is recommended for the reason that it has a low cost. Therefore, if necessary, such pumps can be set several in front of the instruments that cannot work without pressure. The design assumes the presence of smart automation that protects the device from dry stroke, this indicates that the equipment turns off when water disappears in the pipe. If you have to install an increase in water supply pump, then you can choose the equipment that works at the expense of water cooling. Most often, such aggregates have the ability to work in one of the two modes. Among them can be allocated automatic and manual. The master must only remember that such a device does not tolerate dirty water. Therefore, if the water in the pipes has extraneous inclusions, the pump will have to be cleaned periodically.

Conducting installation work

Installing an increase in water supply pump is made in several steps. It is completely easy to carry out such work, however, before starting manipulations, you need to get acquainted with technology. The first step will be the markup in the place where installation work is expected. Next, the master should block the water and open the faucet crane to eliminate the extra pressure. Using will need to cut a piece of pipe, following the tags. In terms of edges, a thread must be cut, and after screwed the threaded adapters. Installation of the boost pump at the next stage involves the use of American fittings, which are supplied with the equipment. They will need to be connected to adapters.

Final work

The wizard will have to install the pump for the designated place. To connect the power cable you need to use a waterproof outlet. It is recommended to install an automaton in 10 milliamm. These recommendations will allow you to work correctly.

With a centralized supply of water in the apartment of multi-storey houses, residents of the upper floors may experience inconvenience due to a weak water pressure. For the normal functioning of the washing or dishwasher, heating the water of the gas column, pressure is required in the plumbing system from two to four atmospheres. At lower pressure, this technique will not work. A weak jet of the crane, or the complete absence of water, do not make it all happy if necessary to wash the dishes or take a shower. In order to normalize the water supply situation, the inhabitants of height should use pumps to increase water pressure in the apartment.

Installation of the pump in the apartment will be required only when the cause of insufficient pressure is not scored water pipes, and other problems of which require the global modernization of water supply throughout the house.

1 Need to install

Own water pumps in the apartment are installed to create and support acceptable working pressure, taking into account all water consumption points. With the simultaneous use of the water resource in several places there is a natural reduction in pressure in the general system.

Normal pressure for the apartment with domestic use of water is considered to be an indicator of four atmospheres. This is enough that it does not fail in the work of the washing machine, the shower, the jacuzzi, the gas column, which have automation to turn off the device with insufficient pressure.

The occurrence of increased pressure is possible. The indicator of seven and more atmospheres, leads to damage to household appliances and individual elements of the water supply.

With a technically competently calculated and normally mounted water pipeline, there are situations with pressure drops due to peak consumption. For example, in the evening, when most tenants come from work and begin to do homemade affairs, water consumption increases sharply. This leads to an offensive situation, when everything is in order on the lower floors, and it is even problematic to wash the hands at the top.

Pump to increase water pressure, mounted directly on the feed line, is able to provide a complete and stable comfort of use of water at any level of a multi-storey house.

2 What is worth paying attention to?

The water pump installed in the apartment may have two types of management:

• manual - requires constant control when pumping a pump;
• automatic - the operation of the device is adjustable using special sensors (pressure, pressure, duct).

Installing the device for supplying water with manual control is suitable for irregular use. And human control is necessary to exclude the work of the pump to dry. If there will be no water in the central water supply, there will be an electric motor overheating, and it burns.

Pumps with automatic control do not require any attention. They can be included constantly, as their work is regulated by automation, depending on the emerging situations.

The water temperature in the central water supply is also important, since individual models that increase the pressure can work as follows:

• only with cold water;
• only with hot water;
• and cold and hot (universal device).

An important factor in the work of the supporting water pressure in the apartment of the unit is the method of its cooling:

Air cooling causes an increased third-party noise, but the performance of such a device is higher than that of its water-cooled fellow, which works almost silently. Used in in pipelines for both cold water and hot.

2.1 Important characteristics

Since the water pump will be installed directly in the apartment, some of its characteristics should be taken into account:

• power - how it is higher, the greater the number of consumption points will be provided with sufficient pressure;
• noise level - an important factor that should be taken into account to comply with a comfortable noise atmosphere in the apartment. Too noisy aggregates are not suitable, especially when working at night;
• the diameter of the pipes in the apartment - an increase in pressure is possible only in the case of a complete correspondence of the cross section of the pipeline and pump nozzles;
• lifting height - Each swing unit is designed for a certain height of fluid delivery;
• overall dimensions - for an apartment that has limited spatial capabilities to install this kind of equipment, compact aggregates should be selected.

3 Installation in the apartment

Installing the pressure increase pump in the home pipeline will allow for a long time to ensure all domestic needs in water.

In order for the equipment to work smoothly, you should take advantage of the following recommendations:

• the flow of fluid into the pump should occur through a coarse filter. Thus, it is eliminated to enter the water inwards of the unit of solid particles, which can cause mechanical damage;
• location only in a dry and heated room, to prevent the corrosive influence of moisture and the negative effect of low temperatures;
• mandatory presence of a locking valve (crane) installed before the pump, which will allow prophylactic and repair work when disconnected from the central system;
• reliable fastening - ensure the absence of leaks caused by constant vibration of the working unit.

Installation of equipment capable of improving the pressure of water in the apartment, occurs in this way:

• water supply overlaps in an apartment;
• marker on the carrier pipe selected for the installation of the pump, marks are made, taking into account the overall dimensions in length and the presence of adapters;
• on the marked places there is a pipe;
• on the outside of the free ends of the pipe, the screw carving of the desired step is cut;
• at the ends of the pipes are screwed adapters with internal thread;
• adapters are completed with fittings;
• a pump is established in compliance with the correct direction of the movement of the liquid specified by the arrow on the instrument housing;
• a trigger cable from a domestic power source is carried out;

At the end of the mounting work, you need to test the device for checking the leakage in the connections. For absolute sealing, it is recommended to use FMU ribbon by wrapped it on a threaded connection.
