Choosing the right booster pump: count the taps and showers that will run at the same time and how high the water must go (a double-storey house needs more head than a single storey). Each 10m of head is about 1 bar of pressure. Pick a pump whose head at your flow is comfortably above what you need. Not sure? Send us your setup (tank position, number of bathrooms, storeys) and we will recommend a pump.
