Shallow Well Loses Prime: Check Valve Failure

Foot Valve at Bottom of Suction Line Holds Prime

A check valve (foot valve) at the well end of the suction pipe prevents water from draining back when the pump stops. If the pump loses prime in minutes, the foot valve is leaking. Pull the suction line to inspect or replace the foot valve. Hire a well service professional unless experienced.
