Short answerCheck that the pump is plugged in and the breaker is on, lift the float to see if it starts, and make sure the discharge line isn't frozen or blocked. If it won't run, move belongings off the floor, use a wet vac or temporary pump, and schedule a replacement with a battery backup.
Quick checks
- Power and GFCI outlet
- Float stuck
- Discharge line frozen or clogged
- Check valve

Preventing the next failure
Test the pump each spring by filling the pit, replace pumps around the end of their typical life, and add a battery backup or water-powered backup where power outages come with storms. A high-water alarm gives early warning.
