Sump Pump Maintenance Checklist
Test your sump pump quarterly. Failure during a storm causes basement flooding — maintenance takes 15 minutes.
Pour a bucket of water into the sump pit — the pump should activate, discharge water, and shut off. Clean the pit of debris annually. Check the discharge line for clogs and ensure it drains away from the foundation.
Install a battery backup pump ($150–$400) for power outages during storms — when sump pumps are needed most. Consider a high-water alarm that alerts your phone.
Sump pump failure is a leading basement flooding cause. Standard homeowners insurance often excludes sump pump overflow without a water backup endorsement.

Frequently Asked Questions
How often should I test my sump pump?
Quarterly, and always before spring thaw and hurricane season. Pour a bucket of water into the pit to trigger the float switch.
Is sump pump failure covered by insurance?
Often no — requires a water backup endorsement ($50–$100/year). Standard HO-3 excludes sump pump overflow.
