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

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 effluent 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 fall or tilt onto one side. This can jam the float
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.
• Replace the tether switch every two (2) years. This maintenance will reduce the risk of improper pump operation, switch failure
and/or flooding.
