broken or dirty valves.
and replace if needed
on most pumps are made of a plastic cage with a metal seat.
Sometimes the cage will break due to debris in the supply water,
allowing the valve to float. The metal valve seat could be
worn or scored due to
dirty supply water. The
valve assembly sits on an o-ring that fits between the valve
assembly and the head of the pump. Click
here for a selection of replacement valve assemblies.
Check this o-ring for wear and the brass seat for scoring.
Usually this condition is caused by cavitation due
to insufficient water supply. Cavitation in this area will
destroy your pump. The worm holes under the o-ring are in the head
of the pump and not fixable. Fixing your water supply
problem and replacing the valves and o-rings will help for a while
but the problem will soon return as the pressurized water will
work it's way under the o-ring, through the wormholes. For
