What should I do if my sump pump stops working after heavy rain?

If your sump pump stops working after heavy rain, cut power, check the outlet and breaker, and call for same-day help if water is rising. The most common storm-related issues are power loss, a tripped GFCI, or a stuck float switch. We handle these calls throughout the Bloomfield area with same-day and emergency response. A quick bucket test often tells a tech whether the float switch or impeller is the problem.

Try these steps if it’s safe and the water isn’t near electrical parts:

• Reset the GFCI and breaker, then plug the pump into a different outlet to rule out power.
• Pour water into the pit; the float should rise and the pump should start within seconds.
• Check that the discharge line isn’t frozen or clogged and that the check valve arrow points away from the pit.
• If the motor hums but doesn’t pump, you may have a blockage; if it’s dead or smells burnt, plan for replacement.

Do not reach into the pit or water while the pump is plugged in.
