Why is my pump not holding pressure

If your pump is losing pressure during use it will be cycling, that is frequent stopping and starting while in use. Go through the following checklist to troubleshoot the problem:

  • If you have a pressure tank it may require checking, it should be at least 130 kpa. Refer to your pump manual.
  • You may have leaking taps, float valves or a fault in the pipework. This will also cause the pump to turn on and off while not in use.
  • If you have an auto restart controller fitted to you pump it may have a fault result in cycling, consult your local dealer if this is occurring.
  • The check valve or foot valve may be leaking, resulting in water flowing from the pump to the water source ie: tank or dam. This will mean that the pump will start while not in use.
  • If you have filtration attached to your house, filters may be blocked and require changing.
  • In some cases outlets within the house may become impeded by debris from your tank.
  • In some cases the impeller in your pump may be partially blocked causing pressure loss, or your pump may have a leaking seal and this may result in a pool of water at the base of your pump.
