Water Pump Solutions – In the UK, OfWat guarantees that a certain minimum water pressure reaches the boundary of each property in the country. Known as the Guaranteed Standards Scheme (GSS), it should be 9 litres per minute at a pressure of 10m head or just under 1 bar. Anything more than this should be considered a bonus. It should be noted that this is the pressure received at the boundary and does not mean that this is the pressure that reaches the tap or the shower.
