What to Expect with Sump Pump Not Working
A sump pump that isn't working is a serious problem, especially during or before heavy rain. Before calling a contractor, run through these quick checks: (1) Is the pump plugged in and is the outlet working — test with another device. (2) Is the circuit breaker tripped? (3) Is the float switch stuck? It should move freely up and down in the pit.
If those checks don't solve it, the issue is likely a failed motor, a burned-out capacitor, or a seized impeller from debris. These require professional diagnosis. A technician will first test the pump electrically, then inspect the float mechanism, then check for mechanical blockage.
Don't wait on this one. Heavy rain can arrive with little warning, and a basement without a working pump can take on water fast. Most contractors in our network offer same-day service for non-working pumps during peak storm season.

Frequently Asked Questions
How much does sump pump not working cost? ▼

A good rule of thumb: if the repair cost exceeds 50% of a new pump's installed price, replace it — especially if the pump is over 7 years old. Our AI chat can walk you through the diagnostic questions a technician would ask to help you figure out which situation you're in.
