Electric pump for water supply

Without running water, life in apartment buildings is unthinkable. But not always its presence pleases apartment owners. It’s all about the water pressure, which can be so low that household appliances such as a washing machine, dishwasher, gas water heater simply refuse to work. It even comes to the point that water does not enter the upper floors of houses at all. If it is impossible to somehow increase the total pressure, then you can do this only in relation to your apartment by installing a pump to increase the water pressure in the apartment. Of course, such a step would be rational if the reason for the low pressure does not lie in the supply water riser or clogged water pipes.

In what cases are used

The water pump for increasing the water pressure in the apartment is designed to create an acceptable pressure in the water supply. If the pressure in the region of 4 atmospheres is the norm, then in practice we record its decrease to a value of 1-1.5 and even lower. And to work, for example, a washing machine requires a pressure of at least 2 atmospheres. A jacuzzi and a shower cabin will not want to work at such a pressure at all, since they are designed for 4 atmospheres. However, even higher pressure is dangerous for pipelines. Already at a pressure of 7 atmospheres, some elements of the water supply network may be damaged. Therefore, the pressure must be within certain limits and be stable .

It is especially disappointing for the residents of the upper floors during rush hours, when, having come from work in the evening, it is impossible even to wash properly. At the same time, the inhabitants of the lower floors have a normal pressure. In this case, a circulation pump for increasing water pressure, embedded directly in the inlet water main, is able to give residents a complete sense of comfort.

What parameters differ in booster pumps

Pumps that increase the pressure of water in the water supply system differ in several ways:

1. By type of management.

  • Manual control , in which the device is constantly on or off. The owners only make sure that there is water in the system. When working “dry”, the serviceability of the device is not guaranteed. It can just burn out from overheating. Therefore, such a device turns on when performing some one-time operations, and after their completion it turns off;
  • Automatic control . A special sensor turns on the unit when the need arises. The same sensor turns off the automatic water pressure booster pump when there is no water in the system.

2. According to the permissible temperature of the water in the pipes.

The fact is that not all household pumps for increasing the water pressure in an apartment can transport cold and hot substances. This indicator should be guided when buying a pump.

There are 3 types of pumps:

  • apparatus for cold water only;
  • device for pumping only hot water;
  • universal device for working with liquids of any temperature.

3. According to the pump cooling method. The cooling system protects the pump from possible overheating.

Can be of two types:

  • Cooling by the flow of liquid flowing through the pump (“wet rotor”). They work almost silently. May overheat if operated without water;
  • Cooling by rotating blades mounted on a shaft (“dry rotor”). Such devices are characterized by an increased noise level, but greater productivity.

Features of self-priming pumping station

In apartments located on the upper floors of high-rise buildings, water may not reach at all. The way out in this situation is to install a self-priming pumping station. A typical station consists of a pump, a pressure switch and a membrane tank (hydraulic accumulator). The pump supplies water to the tank, from which it is supplied to the water points under a certain pressure pre-set by the owner using a pressure switch.

Pumping station with Wilo accumulator

Tip: Some pumping stations may be without a hydraulic accumulator, but it is recommended to purchase equipment with an accumulation tank into which water will be pumped. The larger it is, the longer the station will last, since the pumping unit will turn on less often.

The station pumps liquid into the tank, after which it turns off. However, the consumer can use the water from the tank even if it is not in the water supply at all. When the water leaves the tank, the relay will turn the station back on.

Note that such a pump can also be used to increase the water pressure in the country, both for water supply and for irrigation.

Before buying a station, check its maximum pressure. For example, a Grundfos JP Booster 6-24L self-priming water pressure booster can supply water with a maximum pressure of up to 48 m, and its tank volume is quite impressive – 24 liters.

What to look for when choosing

When buying an electric water pump to increase pressure, check with a consultant for the following nuances:

  • power. The more powerful the device, the more consumers will be able to enjoy its benefits. Consider the number of taps in the apartment and household appliances connected to the water supply;
  • noise level, which is different for different models;
  • certain pump models are designed for specific pipe sections. If you use a device for a water supply system with an inappropriate cross section, the pump will work with overloads, and the pressure will be less than the calculated one;
  • the height of the water level. A pump for water pressure in a water supply system, designed for a lower load, may simply not reach the liquid to the desired level (this item applies to the purchase of a pumping station);
  • the size of the unit also matters, because sometimes it has to be installed in very small rooms in which the entrance to the apartment is located;
  • An important factor is the reliability and fame of the manufacturer.

Installation of equipment in the apartment

Installation of a water pressure booster pump in an apartment is carried out in the following sequence:

Pictured is a booster pump for water

  1. The pipe on which the pump will be installed is marked taking into account the length of the pump and adapters.
  2. Water is shut off in the apartment.
  3. The pipe is cut in two marked places.
  4. A thread is cut from the outside of the cut ends of the pipe.
  5. Adapters with internal threads are screwed onto the pipes.
  6. The fittings included in the kit are screwed into the adapters. When installing the pump, be guided by the arrow on the body of the device, which shows the direction of fluid flow.
  7. A three-core cable is pulled from the electrical panel to the pump. It is advisable to equip a separate outlet near the pump, and connect the pump through a separate RCD.
  8. Turn on the pump and check it. Pay attention to the absence of leaks from under the fittings. Tighten fasteners if necessary. For better sealing, use FUM tape by winding it around the thread.

Mounting Recommendations

Proper installation of a pump to increase the water pressure with automatic control will ensure the water needs of the apartment for many years to come. During the installation process, adhere to the following recommendations:

  • For longer operation of the device, it is highly desirable to install a mechanical filter at the inlet to the pump. Thus, you will protect the equipment from foreign particles entering it;
  • The device must be installed in a dry place in a heated room. At negative temperatures, the water in the pump may freeze, damaging the inside of the device;
  • A shut-off valve must be installed upstream of the pump. This will make it possible to carry out preventive maintenance of equipment when the water flow is turned off;
  • Gradually, during operation, the vibration acting on the pump can loosen the device, which may cause leaks at the points of its attachment. Therefore, first check the tightness of the connections.

A properly selected and correctly installed pump to increase the working water pressure in an apartment water supply will solve your problems associated with a low level of water pressure in an apartment of any number of storeys.

You live in a private house or apartment in an urban high-rise building, where the water supply system is connected to public pipelines. During peak hours, the pressure drops sharply, as a result, the instantaneous water heater and washing machine do not turn on. – Unable to take a shower. You made the right decision: you need to buy a pump to increase the water pressure. Which? Certainly the best. We bring to your attention the best booster pumps. Choose.

Low pressure in the water supply system can infuriate not only you, but also expensive equipment. Agree, both of them just need to be protected. Such situations mainly oppress the owners of private houses, but they also happen in apartments connected to centralized networks. How to deal with them?

Pumps to increase water pressure will permanently get rid of these troubles. They will provide the operating parameters required for the normal functionality of household appliances. Compact, almost invisible devices will protect your nerves and extend the life of the units.

The article presented to your attention details the principles of equipment selection and the rules for its installation. Useful schemes will help those who wish to carry out the work themselves or control the hired plumbers. The information is supplemented by photo-collections and videos.

The operation of the pump to increase the pressure in the network

The problem of low pressure in the water supply is solved using two types of devices: circulation and self-priming pumps. The former are simpler and easier to assemble into the system.

A conventional circulation pump consists of a rotor, an impeller mounted on it and an engine that rotates it all. Usually, if there is water in the system, but its pressure is weak, one or two pumps are enough.

But if water does not flow to the upper floors at all, you will have to install a high-power pumping station with a hydraulic tank. Such a device is simply installed as part of a plumbing system in a suitable location. The impeller spins, giving the water flow additional acceleration.

As a result, the pipes fill with water faster, providing the necessary level of pressure in the water supply. These are compact low power devices designed to solve local problems. Suction pumps are characterized by higher performance and more complex device.

In addition to a suction pump capable of pumping water to a considerable height, the system is also equipped with a hydraulic accumulator equipped with a special membrane.

The operation of this technique is automated, a pressure switch is used. Water is first supplied to the storage tank, and then enters the water supply, providing the necessary characteristics within the system.

Thus, if a centrifugal pump allows you to eliminate the problem in a particular area, then suction equipment is used to regulate the entire plumbing in a house or apartment.

Self-priming booster pumps are capable of lifting liquid to a height of up to 12 m, while their capacity starts from 2 m 3 / h.

Increasing water pressure pump works as follows. When the water flow reaches 1.5 cubic meters, the motion sensor petal changes position.

This will automatically turn on the pump. When the water flow stops, the pump turns off. This type of equipment is used both in private cottages and in apartment buildings.

It is especially relevant in high-rise residential buildings, where it is impossible for various reasons to ensure the normal delivery of water to the upper floors without a special pump. Installing a single pump or even a special station with increased power can be a real salvation for residents of the upper floors.

Sometimes you have to use not one booster pump, but two or more. Such a need is sometimes faced by owners of houses in which the plumbing system was originally designed with errors.

In this case, you will have to calculate the cost of reworking the water supply (if such a possibility exists at all) and the cost of installing additional equipment.

It should be remembered that special types of equipment are designed for pumping hot water. They are made of special heat-resistant materials, so they are more expensive than simpler models designed for contact only with cold water. There are also universal booster pumps that are suitable for both cold and hot water.

The power of a conventional circulation pump is small, it consumes less energy than some incandescent lamps.

When it is included in the system, it is possible to achieve an increase in pressure by about 2-3 atmospheres. If more serious correction of characteristics is required, more powerful equipment should be preferred.

Circulation pumps tend to work “to a dead end”, i.e. they do not need to be turned off even if all taps are closed and no water is taken from the system. Inlet pumps operate in approximately the same way to increase water pressure. These devices are similar in design to circulation models.

If such a pump is turned off, water will circulate freely through its housing. As soon as power is supplied to the motor, the pump turns on. The impeller begins to rotate and the water pressure in the system increases. When faced with a choice between automatic or manual systems, the former is usually preferred.

It is more convenient to use such equipment, and it lasts longer, because it does not work idle. It makes sense to take a manual pump only in cases where it will be used either for a very short time (temporary option) or extremely rarely (in summer, in the country, only on weekends).

The concept of dry and wet rotor refers to information about the cooling system of the device. In the first case, it is cooled by the air flow, and in the second – by the flow of pumped water.

A wet rotor pump is cheaper, but lasts less due to the negative effects of sediment that accumulates during pumping water on the working parts. Models with a dry rotor cope with their tasks more efficiently, and their service life is longer.

Rules for selecting the power of the unit

The power of the device must be commensurate with the needs of the system. Lack of pressure is bad, but too much pressure is not needed.

If a too efficient pump is selected for the water supply, the pressure in the system will increase, and all its elements will be subjected to unnecessary additional load. This leads to rapid wear and frequent breakdowns.

Stable water pressure in the system should not be less than two atmospheres. This is enough for comfortable water procedures, as well as for starting an automatic washing machine.

Although some models are more demanding in terms of operating conditions. For example, if the house has a shower, hydromassage, jacuzzi or other similar devices, the pressure should be higher.

In this case, it is better to increase the pressure in the plumbing system to 5-6 atmospheres. Certain types of equipment require even higher performance.

Therefore, the first step before installing a pressure boosting pump should be to study the documentation of household appliances. If any devices are planned to be purchased in the future, their characteristics also need to be taken into account.

Accurate calculations can be made by a specialist, but preliminary data made “by eye” are usually sufficient. To determine what pressure really exists in the system, you can use a regular liter jar. The water is opened and measured how many liters of water poured out of the tap within a minute.

Then you need to deal with current needs. If the inconvenience is due to the fact that it is difficult to take a shower with an open tap in the kitchen due to low pressure, it is enough to use a conventional pump that will increase the pressure by a couple of atmospheres.

But if the house has an automatic washing machine, shower or other equipment of this kind, you should study the technical documentation.

Each such consumer requires a certain pressure of water. Lack of sufficient pressure can lead to costly equipment running idle.

Household appliances, especially foreign-made ones, are not designed for such operating conditions. A failure caused by a lack of normal pressure can be considered as a case that does not comply with the warranty conditions.

You can focus on the maximum pressure in the plumbing system indicated in the device passports. In the presence of a large number of such equipment, it is worth contacting an engineer for advice.

When choosing a model of a water pump suitable for increasing pressure, one should also take into account the needs of equipment, the purchase of which is planned in the future.

Principles of installation of self-priming models

Installing this type of pump is not difficult. This will require approximately the same skills and tools that are needed to install other types of pumping equipment.

Schematically, the installation of a booster pump can be represented as the following steps:

  1. Choosing a location for the accumulator and pump.
  2. Installing a hydraulic accumulator.
  3. Installation of pipes for connecting equipment to the water supply.
  4. Hanging the pump on the wall.
  5. Tying the pump and accumulator.
  6. Checking the operation of equipment in automatic mode.

In fact, a pump and a hydraulic accumulator with a pressure switch is a variation of a pumping station. To implement the installation of such a system of devices, you first need to find a place to place the tank.

Some craftsmen replace the accumulator with a membrane with a conventional large capacity, for example, a 200 liter plastic tank.

Instead of a pressure switch, the tank is equipped with a float sensor to ensure that it is automatically filled as needed. Such a tank is installed as high as possible: in the attic or on the top floor. Immediately you should think not only about the size, but also about the configuration of the container.

The flat and narrow tank will take up less space than a traditional cylindrical model. Although there are no special requirements for the capacity configuration. When choosing a place for a container, access to the tank / accumulator or the possibility of easy dismantling of this element should be provided. This is necessary to perform maintenance, repair or replacement of the device.

Hydraulic accumulators are supplied ready for installation, but the tank should be prepared. It has holes for water inlet and outlet. You can also make a separate shut-off valve to drain water in an emergency. Branch pipes for supplying water to the tank and taking it into the water supply system are mounted to one water pipe.

In modern conditions, for the installation of water supply, it is more logical to use easy-to-install and reliable plastic pipes.

To prevent air from being sucked into the tank from the pump, and also to prevent water from entering there when the equipment is turned off, check valves should be installed on both pipes. After that, pipes are mounted, with the help of which the tank is connected to the plumbing system.

After the tank or accumulator is installed, and the necessary water pipes are laid, the installation of the suction pump can begin. Usually such a device is delivered unassembled. It is first collected, and then proceed to installation.

If you decide to mount the pump on the wall, you should first make markings for fasteners. Then the pump is suspended and connected to the water supply pipes. In general, this is not a very difficult operation. An important point is the direction of the liquid in the pump. It is indicated on the case with special marks.

The pump should be installed in such a way that the movement of water is from the tank to the water points. Thus, the scheme for installing and connecting a pressure boosting pump is as follows: accumulator-pump-consumer. Then the pump is tied.

All connections must be carefully sealed. If threaded connections are used to connect the booster pump, a suitable seal should be used: FUM tape, linen thread, etc.

The amount of sealant should be sufficient, but not excessive. The device is connected to plastic pipes using special fittings.

After that, you should check the operation of the entire system. If a tank with a float sensor was used, it is filled with water. Check not only the operation of the sensor. The container that serves as a storage tank should be checked for leaks. If everything is in order, you can proceed to testing the operation of the pump itself.

The pump must be connected to the electrical network. It is recommended that the pump switch lever be set to the automatic position. It remains to open the nearest water tap and observe the operation of the device. If the installation is done correctly, the pump should automatically turn on, and the water pressure will increase noticeably.

Similarly, the installation of pressure boosting circulation pumps is carried out. For them, they choose a suitable place in the water supply, and cut it there. In this case, it is also extremely important to correctly connect the pump, taking into account the direction of fluid flow. If the position of the device is incorrect, the pump will still let the water flow through.

But his work will be extremely inefficient, since the device simply will not function. The instructions and on the housing detail the correct position of the pump.

After installation, the pump is connected to the mains and its operation is checked. If the water pressure at the nearest water intake point has increased, then the installation is done correctly.

Installing a system with a hydraulic accumulator looks a little more complicated. First you need to deal with the device of the entire structure.

The pump is connected to the accumulator using special hoses. Then a pressure switch is connected, with which the equipment will turn on and off.

The relay setting deserves special attention. Before starting work, it is recommended to carefully study the instructions and recommendations of the manufacturer.

If there is not enough knowledge and skills for high-quality installation and configuration of equipment, it is better to contact a specialist for advice or completely entrust him with all the work.

Some Helpful Tips

Not always a booster pump is needed to solve the problem with low water pressure in the system. To begin with, it does not hurt to diagnose the condition of the water pipes. Their cleaning or complete replacement can restore normal pressure without additional equipment.

To understand that the problem is in the poor condition of the water pipes, sometimes it is enough to ask neighbors who live in apartments on the same floor or higher. If they have normal pressure, you almost certainly need to clean the pipes.

If the picture is the same for everyone, there may be more serious problems affecting the entire plumbing system of the house and even the area. In high-rise buildings, water sometimes simply does not flow to the upper floors. This requires high-powered and rather expensive equipment.

It makes sense to cooperate with other tenants to share the costs. It is a good idea to demand that the organization that receives the payment for the water supply solve the problem, since it is they who must ensure the supply of water to the consumer.

The lack of water on the upper floors is a violation of fire safety requirements. When communicating with the water service provider, it is worth paying attention to this point and mention the possibility of litigation due to non-compliance with the law.

It is best to entrust the installation of equipment in an apartment building to a full-time plumber of the management company. He is also more familiar with the system, and will be held responsible in case of leaks or breakdowns caused by poor-quality installation of equipment.
