What is water pressure?

Water pressure is the force water is delivered into your home.


It’s measured in bar or psi (pounds per square inch). For example, 1.0 bar equals 14.5psi. One bar of water pressure is needed to raise water 10 metres high. This is often why flats and high-rise buildings require greater water pressure than other homes, as the water has further to travel.


The amount of water pressure in your home will vary depending on a number of factors, including the time of the day and the ground level of your property. However, while these factors play a part, your water authority is required to supply a minimum of 0.7 bar of pressure.
