Household Pump Maintenance

This tip has been provided by Think Water Peats Ridge.

Does the pressure in your shower fluctuate? Does your pump start and stop rapidly?

Pumps equipped with pressure tanks require regular servicing to extend their working life and to reduce running costs. A pressure tank stores a supply of water under pressure to provide a buffer for your plumbing system. This works to minimise pump operating time and maximise the life of your pump unit.

Like the tyres on your car, the pressure in your pressure tank needs to be checked regularly.

The following is a quick guide for determining whether your household pump requires maintenance.

  • Step 1 - Determine the cut in pressure of the pump unit. If the pump is equipped with a pressure gauge, stand by the pump whilst someone opens a tap nearby. Take note of the pressure on the gauge when the pump starts. This is the cut in pressure.
  • Step 2 - Turn off the power to the pump unit.
  • Step 3 - Turn off the water supply to the pump from the tank.
  • Step 4 - Open a tap nearest to the pump until the system is completely drained.
  • Step 5 - Use a tyre pressure gauge to check the pressure in the tank.
  • Step 6 - The pressure required in the tank is 10% less than the cut in pressure. eg. cut in pressure 20psi or 138kpa less 10% therefore pressure tank should have 18psi or 124kpa. A 12-volt or 240- volt compressor should be used to increase pressure in the tank if it is low.

If your pump is not equipped with a pressure gauge, visit our Store Locator to contact your local Think Water store who will be able to advise you of the correct pressure setting for your pump system.
