A sump pump sits quietly in your basement doing nothing — until a heavy storm hits and it's the only thing standing between you and a flooded basement. That's exactly why regular testing matters.
Test it quarterly
Pour a bucket of water into the sump pit until the float rises. The pump should kick on, pump the water out, and shut off. If it doesn't, it needs attention before the next storm.
Routine maintenance checklist
- Clear debris from the pit and inlet screen
- Make sure the float moves freely and isn't stuck
- Check that the discharge pipe is clear and directs water away from the foundation
- Confirm the check valve is working (prevents backflow)
- Listen for unusual grinding or rattling noises
Consider a battery backup
Storms that flood basements often knock out power at the same time — right when you need the pump most. A battery backup system keeps it running during an outage.
Know the lifespan
Most sump pumps last about 7–10 years. If yours is older, replacing it proactively is far cheaper than a flooded basement. A plumber can assess yours and recommend the right capacity for your home.
