Make sure the pump is plugged into a working ground fault circuit interrupter (GFCI) outlet and the cord is in good shape. In damp areas, GFCI breakers may trip and shut off the pump, so check in periodically so you can reset it if necessary.
A Basic Sump Pump Maintenance Checklist
Most sump pumps are equipped with water level or flood alarms that alert you if the pump isn't working properly, and sump pumps on the whole are quite reliable. But as with any important piece of equipment, regular maintenance is a good idea — spend a few minutes in the fall and spring, when heavy rains are forecast, on these basic jobs.
Check the GFCI Outlet
Make Sure the Pump Stands Upright
Vibrations during operation can cause the pump to fall or tilt onto one side, which can jam the float arm so it can't activate the pump.
Test It With a Bucket of Water
Periodically pour a bucket of water into the pit to make sure the pump starts automatically and drains the water quickly. If it doesn't start, have it serviced.
Clean the Submersible Pump's Grate
Physically remove the pump from the pit and clean the grate on the bottom; the pump's suction can pull small stones into the grate, blocking the inlet or damaging the pump over time.
Check the Outlet Pipes
Make sure the outlet pipes are tightly joined together and draining out at least 20 feet (6 meters) from your foundation.
Check the Vent Hole
Make sure the vent hole in the discharge pipe is clear.
