Booster systems, also known as booster pumps, are used to maintain pressure in the water supply system. They can be used for several purposes:
- flushing the toilet
- a second or third shower in the house
- multiple washbasins
- appliances such as dishwashers, washing machines and coffee machines
When several appliances are supplied with water simultaneously, the pressure in the water pipes will drop automatically, which, for example, affects the amount of water coming from the shower or tap. This is where booster systems come in handy.

If you are looking for a booster pump, we will be happy to help you find the appropriate model. Please refer to our pump configurator. If you specify your wishes and requirements, the configurator will work out which pump best fits your situation, and you will be assured that you are choosing the right one.

Operation of a booster system
A booster pump draws in water via the suction connection, and it is then pumped into the pressure vessel. The pump switches off automatically when the pressure vessel is full, by which time it usually contains about 20 litres of water. The booster pump is also connected to a drainpipe, which, for example, may lead to several draw-off points (e.g. a number of taps) throughout the house. If a draw-off point (e.g. a tap) is opened, water is transferred directly to it from the expansion vessel. If only a small amount of water is required, the pump does not need to switch on, because the expansion vessel contains enough water to supply the tap. As soon as the water level in the pressure vessel is about to drop too low, the pump switches on automatically to refill it, and switches off automatically when it is full again.
Different types of booster systems
In principle, a booster pump is a garden pump fitted with a pressure switch and an expansion vessel. Without the related accessories, a garden pump does not switch on or off when water is required, but will run continuously. By equipping it with a pressure switch, the pump is converted into a booster pump, but one without a pressure vessel, as shown in the photo on the left. The advantages and disadvantages of each type of installation are specified below.
+ The pump stops automatically when the tank is filled
+ The pump starts automatically to replenish the water level
- Takes up more space
Without a tank
+ Is smaller because it has no tank and is therefore more suitable for extra small spaces
- Always has to run when water is used, resulting in noise and higher energy consumption
Waterpump.us recommends using a booster system with a tank, as shown in our collection.
Installing a booster system
A booster system must be installed in a well-ventilated, dry, and frost-free place, preferably one that is also easily accessible. The following is also important:
- The pump requires an earth connection
- The pump should be placed in an elevated position, which means not on the ground
- The system's inlet should be fitted with a safety valve
- The safety valve should be fitted with a filter (which needs to be cleaned frequently)
- The water supply pipes are connected with special pvc or brass connecting pieces, which have an insertion part on one side and a screw-on nozzle part on the other. If the system is placed outdoors, we recommend using brass connecting pieces.
