Made in Britain, ShowerPowerBooster can add 3 or 4 metres pressure head to your tap or shower and improve flow and performance of your tap or shower (better than moving your cold header tank from the loft to the roof apex).

There are 2 basic choices of where to fit a single or pair of ShowerPowerBoosters (detailed drawings are in the booklet sent with the pumps).

To boost every tap and shower in a house go for a SP2B as a hot water pump only or a pair of pumps (SP22S) to boost hot and cold. If you the pumps immediately next to the hot water cylinder, the pumps can boost every tap and shower in the house (The Whole House Solution). Reliable and easy to fit.

If you fit my pumps only on the pipes that feed only a shower, it will maintain that shower even if other taps are being used in the home (Protected Flow Solution).


Most people get away with just a single ShowerPowerBooster as a hot water pump only pressurising the hot, which should balance an existing cold pressure if the cold is gravity-fed or if the cold is mains-fed. A good mixer tap will balance hot and cold with a pressure differential of 4 to 1, or even 5 to 1 (which is why we have carefully sized the pump as we have – powerful enough but not too powerful so that it unbalances the pressure).
