Many household appliances are plumbed into the water supply and need a constant flow of water to make them run properly.

 

If, however, your water pressure is too low or too high, your appliances may not work to their fullest capabilities or may even get damaged. It is advisable to test your water pressure several times a year and before and after installing new appliances.

 
     
   

What is water pressure?

Water pressure is a measure of the force that pushes water through a system. Water pressure is measured in "bars". One bar is the force needed to raise water through pipes to a height of 10 metres.

 

The higher the water pressure, the greater the force with which water is expelled from a system. If your taps or appliances appear to to have high or low pressure then it may be a tell-tale sign that you need to get your water pressure gauge out.
