Often, in the existing water supply system in the country, the pressure is insufficient. This is a common occurrence if the system is built on the basis of a storage tank and enters the system by gravity. In the best case, we have a pressure of 0,8-1 atm. This is not always enough even for a shower, and you can connect a boiler or washing machine only at 2 atm. There are two ways to solve the problem. The first is by installing a pumping station that automatically maintains the specified parameters. The method is good, but there is not always the required amount of money. The second output is a pump built into the system that increases the pressure in the water supply in the country. This option is much less expensive. Booster pumps and how to use them will be discussed further.
Booster pump for a summer residence: what are
This is a small device that increases the already existing low pressure. That is, they cannot create it from scratch. This device crashes into an existing water supply and pumps up water, raising the pressure by 1-3 atm. There are several types of booster pumps:
- Cooling type:
- with a dry rotor – they have a higher efficiency, but they are noisier and have larger sizes;
- with a wet rotor – the noise level is low, the dimensions are small, but not very effective, although they can cope with an increase in pressure in the country water supply (and not only) by 100%.
- Turn on method:
- manual activation – when it is necessary to increase the pressure, turn it on, when it is not necessary – turn it off; not very convenient: you need to ensure that the pump does not overheat;
- automatic switching on – the presence of flow is controlled by a flow sensor; when a tap or other consumer is opened and there is a certain flow per second, the pump is turned on, when there is no flow, the pump is turned off;
- combined models that, by switching the switch, work either in one or the other mode.
Booster pumps with horizontal and vertical arrangement
- By installation method:
- horizontally;
- vertical;
- in both positions.
- Available speeds:
- single-stage – have one pumping speed;
- multistage – can work with different intensity, which depends on the flow rate.
- By type of construction:
- in-line – compact, but low-performance models built into the supply pipeline;
- vortex – productive, but noisy and requiring special piping.

How to choose
In order not to be particularly confused, a booster pump for water supply in the country is usually taken in-line (embedded) with a wet rotor. This is the most optimal country option: little noise, ease of installation.
Type of installation vertical or horizontal – depends on the place where you will install it. Regarding speeds, of course, multi-stage adjustment is better, but such pumps cost a lot, therefore they are rarely installed in the country water supply.
You can also pay attention to the material of the case. It can be cast iron or stainless steel. Of course, stainless steel is better, but also more expensive. It is necessary to pay attention to the material from which the pump impeller is made. In the cheapest models, it can be made of plastic, in more expensive ones it can be made of bronze or brass.
Specifications and their meaning
First of all, you need to remember that the pump is powered by electricity, and it needs a normal power supply. Basically, they are demanding on voltage. If, suddenly, the selected booster pump does not produce the required pressure, check the voltage. Perhaps it is low and the required work power is simply not achieved.
The main technical characteristics that determine whether the pump that increases the pressure in the water supply system in the country will cope with the task is maximum working pressure. This is the amount that the equipment can output at the output.
The following characteristics are also important:
- Maximum feed. Shows how much water the pump can pump per unit of time. It is measured in liters per minute (l / min) or cubic meters per hour (m.cub / hour). To make it more convenient to compare, translate l / min into liters per hour – multiply the figure by 60, divide the resulting liters by 1000 and get cubic meters per hour. For example, we translate 30 l / min into m30 / hour: 60 * 1800 u1800d 1000 liters per hour, 1,8/XNUMX uXNUMXd XNUMX mXNUMX / hour.
- Max head. This is the amount by which the booster pump can raise water relative to the installation site. This is important if the cottage is two stories or more, and the pump is installed, say, in a technical floor or basement.

We draw your attention to the fact that usually the maximum values u2buXNUMXbare indicated. To find out the real indicators, divide the declared parameters by XNUMX. Then you definitely won’t be mistaken.
Another important thing is at what flow rate the automatic booster pump for giving is turned on. The values can be different: both 0,12 l/min and 0,3 l/min. This figure determines whether the pump will turn on when, for example, the tank is filled in the toilet, or it will start working only after the faucet in the shower opens.
A few words about what modes the pump should work to increase the pressure in the water supply in the country. It is best to take those models that can work both in manual and automatic mode. Here’s why: not all tapping points provide the flow required for automatic switching on. If the device has only automatic mode, you will not help the trouble. But if it can be switched to manual, turn it on before use and enjoy normal pressure. Just remember to turn it off.
The next parameter is maximum and rated power, measured in watts (W). Shows how efficient the motor drives the impeller. In principle, the more powerful the pump, the more pressure it is able to provide, but much still depends on the design and materials used.
Working environment temperature. Measured in degrees. Here everything is more or less clear. There are pumps to increase the pressure only for cold water, there are for hot. This is what this index represents.
Also important connecting dimensions. The booster pump is installed in a cut – a piece of pipe is cut out, a device is installed in this place with the help of fittings. The size of the connecting nuts should ideally match the diameter of the pipe.

Installing a pump that increases water pressure
The installation location of the pumps depends on the specific situation. For the normal operation of the tap and shower, it is enough to put a pump at the outlet of the storage tank, if we are talking about such a system. If you want to put a boiler or a washing machine in the country, other pressure-demanding devices will most likely have to be placed in front of them. With sufficient power (with sufficient flow), one pump can be enough for two devices. Only then it is necessary to think over the scheme accordingly.
In any case, when designing the circuit, consider the possibility of removing or bypassing the pump. This is done using a bypass (there must be a blocking valve in the bypass).
Installing multiple low power boost pumps is not always the best idea. In this case, it may be worth considering more powerful and efficient models that can stabilize the pressure at a significant flow rate. Some of them even provide the rise of water from a well or reservoir, replacing, in a sense, a pumping station.

Pump station for boosting pressure
This outlet is very convenient, but not very cheap, although there are inexpensive models (for example, Gilex Jumbo units cost from $130). These units can lift water from a well or well, but the suction hose can also be lowered into a tank. Then the storage tank can stand anywhere, not necessarily at the top.
Their advantage is that the pressure is maintained constantly, without human intervention (as long as there is electricity). The main thing is to choose the right parameters. They can even be used to increase pressure when connected to a centralized water supply. If you have this option in your country house:
- water is supplied through pipes, but its pressure is not enough even for a shower, not to mention other needs,
- the supply goes by the hour, and you can’t always be in the country at this time, and accordingly, everything remains without watering, then there is no question of such luxury as a shower.
The issue of increasing pressure in the country can be solved with the help of a pumping station and a storage tank
Everything can be fixed by putting a volumetric tank (liters per 1000) and a pumping station. You will have a supply of water and a shower at any time you wish. For irrigation, such a container may not be enough, but no one bothers to put a larger or slightly smaller one. Read about the selection and installation of a pumping station here.
