FAQ's Pumps

Older pumps can have internal wear, such as wearing of the impeller vanes.  This can result in low pressure output.  Alternatively there may be a blockage in the pump.  It is possible to replace worn parts to increase pressure and improve pumping performance.

The slow loss of pressure will cause a pump to keep running then turning off so to maintain a constant pressure.  A dripping tap or slow leak will cause this.
