How often should a sump pump be checked?

Keeping a sump pump in good working order is essential for avoiding basement flooding during heavy rain or rapid snowmelt. For most homes, a routine check every month plus a more thorough seasonal inspection is enough to catch issues before they fail.

Monthly quick checks — In a quick 5-minute cycle, test the pump by pouring a small amount of water into the sump pit to ensure the float rises and the pump activates. Listen for the motor running smoothly and check that discharge lines are clear. While you test, look for signs of corrosion, leaks, or unusual noises.

Seasonal and annual checkpoints — At least once a season, remove any debris from the pit, verify the power connection, and inspect the electrical outlet and GFCI protection. Check the sump’s backup system (battery-powered pump or water-powered backup) if you have one, testing it according to the manufacturer’s instructions. Replace batteries as needed and confirm the backup can operate independently if the primary pump fails.
