Pressure never reaches cut-off
If the gauge does not climb high enough, the pump may keep running because the switch never reaches shut-off pressure.
Pump will not shut off
Well pump runs constantly in Port St. Lucie?
A pump that keeps running may be trying to build pressure but failing. That can point to a leak, low water, damaged pump, pressure switch problem, tank problem, or restriction in the system.
Signs to mention
Pump sounds dry or hot
A pump running without enough water can be damaged. Shut it off if it appears to run dry.
Water is weak while pump runs
Weak flow during constant pump operation can point to leaks, well supply, or pump performance problems.
