Symptoms
Possible Cause(s)
Pump trips GFCI
1. Bad GFCI
2. Bad pump
Pump will not
1. Switch
shut off
2. Switch obstructions
3. Restricted discharge (obstruction in
piping)
4. Excessive inflow or pump not
properly sized for application
Pump operates
1. Low supply voltage
but delivers little
2. Inlet clogged
or no water
3. Broken impeller
4. Pump not properly sized for
application
5. Check valve stuck closed or
installed backwards
6. Shut off valve closed
ROUTINE MAINTENANCE
The pump should be inspected 3-4 times per year for pump movement or buildup of debris on the switch or float. Reposition
pump if it has moved. Remove any debris that could interfere with the operation of the switch. Lack of proper routine maintenance
will void warranty.
• Make sure the pump is plugged in to a working ground fault circuit interrupter (GFCI) outlet and the cord is in good shape.
In damp areas, GFCI breakers may trip, effectively shutting off the sump pump. Check your sump pump and reset the
GFCI if necessary. Replace pump if it continues to trip a known good GFCI.
• Ensure the pump is standing upright. Vibrations during operation can cause it to fall or tilt onto one side. This can jam
the float arm so it can't activate the pump.
• Pour a bucket of water into the pit to make sure the pump starts automatically and the water drains quickly once the pump
is on. If the pump doesn't start, have it serviced or replaced.
