PROBLEM

CORRECTIVE ACTION

Motor will not start

No power to pressure switch due to blown fuses, open switches or loose connections.

Pump pressure switch not closed.

Pump fails to deliver water

Pump not completely primed.

Suction lift is too great.

Foot valve is either not submerged, buried in the mud or plugged.

Restrictor valve is fully closed.

Pump loses prime

Air leaks in suction line.

Well draws down too far and requires a tailpipe.

Faulty foot valve.

For well point installations where pump is losing pressure or unable to prime

Have an electrician install a low pressure cut-off switch to shut down the pump prior to critical failure.

Install or adjust a restrictor valve to offset available capacity.

Add a larger tank (20 gallon or larger) for additional capacity.

PROBLEM

CORRECTIVE ACTION

Pump delivers water but not at rated capacity

Leaks in suction or discharge line.

Foot valve, suction line, impeller or nozzle are partially plugged.

Suction lift is greater than recommended.

Improper setting of control valve on deep well units.

Improper impeller rotation or low speed.

Venturi or diffuser is plugged.

Motor is wired for improper voltage.

Low line voltage at motor.

Filtration cartridge (if used) needs changing or is not installed properly.

Pump starts and stops too often

Faulty air volume control.

Air leaks in tank above the water level.

Incorrect setting on pressure switch.

Tank is water logged or incorrectly charged.

Foot valve leaks or is stuck open.

Can't remove plugs

Use socket and ratchet instead of open style wrench. See PLUG DESCRIPTIONS AND SOCKET SIZES.
