Asked by: Chris Wyble
Water systems which operate at 1.0 bar pressure (10 m of drop) or greater are considered high pressure systems. Those with a pressure less than 1.0 bar are considered low pressure. When you’re ready to choose a tap or shower, you’ll find the water pressure it’s suitable for will be clearly labelled.
How do I know if my water is high or low pressure?
Water pressure is measured in ‘bar’, and generally speaking anything 0.3 bar or below requires a low water pressure tap or shower, and anything at 1.0 bar or above requires a high water pressure tap or shower. There is no middle ground.
