Symptoms
Possible Cause(s)
Pump operates
1. Worn bearings
noisily or vibrates
2. Impeller broken
excessively
3. Piping attachments to building
structure too rigid or too loose
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
1. Bad GFCI
Pump trips GFCI
2. Bad pump
ROUTINE MAINTENANCE
The pump should be inspected monthly 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 war-
ranty.
• 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 pump. Check in on your sewage pump and reset the GFCI if
necessary.
• Ensure the pump is standing upright. Vibrations during operation can cause it to move or tilt onto one side. This can jam the
tether float so it can't activate the pump.
• Flush toilet or run sink 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.
• Replace the tether switch every two (2) years. This maintence will reduce the risk of improper pump operation, switch failure
and/or flooding.
