ROUTINE SUMP MAINTENANCE
We recommend you check your sump pump for proper operation at least once a year.
•
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 in on your sump pump and
reset the GFCI if necessary.
•
Ensure the pump itself 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.
•
Check the inlet screen and clear away any small stones or debris.
