Water Pressure Booster Pump - Automatic & Manual Pack Details

The Water Pressure Booster Pump works to balance Gravity Fed Hot & Mains Fed Cold Systems. The double In Line Micro Pump set is a compact and powerful pump which can be retro-fitted to any shower, tap or hot water system to boost water pressure or flow.

The Automatic & Manual Pack of this water pressure booster offers the easiest and complete solution to balance your gravity fed hot and mains fed cold water supply. Installing these two pumps in line on the gravity hot feed will give your hot water supply a boost to match the cold feed and prevent issues with fluctuations in water pressures or temperatures.
