How to Choose the Best Water Pressure Booster Pump for You

Often for various reasons, the owners of apartments, private cottages, and country houses face the problem of insufficient pressure in the plumbing system. The reason may lie in different circumstances: damaged pipes, blockages, upper floors, remoteness from a water source, poor pressure in the entire system of the city, and so on.


It can bring a lot of inconveniences because household appliances stop working with low water pressure. Here is a pressure booster pump that quickly solves these problems and makes life more comfortable. But for the pump to become salvation, not a torment, you need to follow some rules for choosing the right model.

No. 01 – Determine the Type of the Pump


When you start looking for a booster pump, you will find a huge number of the most diverse and dissimilar models. And they all differ not only by brand and appearance but also by functionality and purpose. By type, booster pumps are divided into two groups.

Circulation Pumps

This is a standard compact booster, which promotes the circulation of water in pipes. They cut it into a particular part of the water supply to increase the pressure and the rate of circulation of water.

Circulation pumps consist of an engine that rotates a rotor with an impeller. This small device injects fluid into the chamber and improves the parameters of the pipeline. Circulating pumps are also divided by the temperature of the water.

  • For cold water. These are the simplest models, made as a rule of cheap plastic. They pump water at temperatures up to 40 degrees Celsius.
  • For hot water. This type is used in the heating and hot water system. The pumps are made of stainless steel and high-quality rubber.
  • There are also universal devices that work with liquids of different temperatures.

Self-Priming Pumps

This unit consists of a surface pump and hydro accumulator. The principle of the self-priming pump is that it can lift water in the pipes, even if it`s not available. Then it pumps a certain level of fluid into the accumulator, on which the system closes.

The battery regulates the level of pressure in the system and maintains it at the required level due to the check valves and an air diaphragm. The device lifts the liquid to a height of 12 m. When choosing a model, note that the circulation pump eliminates the problem in a separate area, and priming equipment is used to adjust the entire water supply in the apartment or private house.

By type of control, booster pumps are divided into:

Hand-operated devices. The device is constantly either on or off. You should only ensure that the system has liquid to avoid the "dry" pump burn. That`s why it is included for performing one-time actions and is turned off after the work is completed.

Devices with automatic control. They are equipped with a special sensor that turns on the device if necessary. When there is no water in the system, the sensor turns off the machine.

The cooling system protects the mechanism from overheating. It can be of two types.

Devices with a “wet rotor” get cooling from the water flowing through a pump. Their work is almost silent, but they can overheat when working without water.

Devices with a "dry rotor" are cooled by rotating blades, which are mounted on the shaft. These pumps have a higher level of performance but are quite noisy.

Pumps also divided according to the method of installation: horizontal, vertical, universal. They differ in the presence of speeds: single-stage - one swap rate; multistage - work of different intensity, depending on the water flow.

So, as we can see, before buying, you should clearly decide what you want to get in the end: pressure increase in one place or throughout the system, permanent work or temporary switching on, power or silence, one speed or several, and so on.

No. 02 – Mind the Following Factors


Power And Maximum Working Pressure

Pump power is essential, as it must meet the needs of the system. This value indicates the performance of the motor, measured in watts (W). It takes into account the number of taps and the characteristics of household appliances.

Insufficient power will make the purchase of a pump meaningless, and too much power can be harmful and cause damage to the equipment. The maximum pressure indicates what the booster can give at the outlet.

Lifting Height

This factor is vital for those who buy a pump for installation in an apartment in a high-rise building. Be sure to find the information about the height at which the pump can lift water. A device designed for lower loads won`t be able to lift the water to a sufficient height.

Size of the Pipe Section

The pressure booster pump cuts into the pipeline, so it`s important that the size of the connecting elements matches the diameter of the pipes. If the device and the pipe have different sections, the pump will work with overloads and the pressure will be less than expected.

Maximum Supply

This parameter shows how much water this device can pump per unit of time: liters per minute or cubic meters per hour. This feature is important for those users who consume large amounts of water.

Installation Location

Many of us consider this fact irrelevant, but much depends on the location of the booster pump: how convenient it will be to install the pump, to operate it, whether it will disturb you during work or not, etc. So, the following two factors also significantly influence the choice of location.

The Noise Level And Dimensions of the Equipment

Before you buy the booster, find out how noisy your chosen model will be. If the noise level is high, it`s best to “hide” the pump away. The size of the equipment is also an important parameter to consider, since you may simply not have enough space to install the pump or in the future, it will be extremely inconvenient to maintain it.

Reliability of the Manufacturer

Read customer reviews and check out the proposed manufacturers. As a rule, large and well-known companies value their reputation and provide pumps that meet high standards. It`ll help you avoid buying low-quality or fake goods.

There are average models that may suit different conditions. For example, among the most popular are wet-rotor pumps, which combine low noise and ease of installation, multi-speed equipment, and equipment that operates in both manual and automatic mode.

Carefully following the selection rules described above, you will definitely not go wrong and buy that very pump that will become your assistant for many years.
