If your home has a basement or crawl space, the sump pump is a quiet hero — until it fails during a storm. Regular maintenance takes only a few minutes and can spare you from a flooded basement and thousands in damage.
How a Sump Pump Works
Water collects in a pit (the sump basin) at the lowest point of your basement. When the water rises, a float switch triggers the pump, which sends water out and away from your foundation.
Test It Regularly
Every few months — and before heavy-rain seasons — pour a bucket of water into the pit. The pump should switch on, remove the water quickly, and shut off. If it does not, something needs attention.
Routine Maintenance Steps
- Clear debris from the pit that could clog the intake
- Check that the float moves freely and is not stuck
- Confirm the discharge pipe is clear and directs water away from the foundation
- Clean the pump inlet screen
- Listen for unusual grinding or rattling noises

Sump pumps fail most often during power outages — exactly when storms hit. A battery backup pump or a water-powered backup keeps you protected when the electricity goes out. It is one of the best investments for flood-prone basements.
Know the Lifespan
Most sump pumps last around 7 to 10 years. If yours is older, runs constantly, or has needed repeated repairs, replacing it before the next big storm is wise.
When to Call a Plumber
If the pump runs but does not move water, cycles constantly, trips the breaker, or fails your bucket test, have a professional inspect it. They can diagnose the switch, check the discharge line, and recommend the right replacement and backup setup for your home.
