Sump pump not working
Answer: call a plumber.
A failed sump pump can turn a dry basement into a flooded disaster within hours during heavy rain, potentially causing thousands of dollars in water damage to flooring, drywall, furniture, and stored belongings. The most common causes are a tripped breaker or power outage (the pump runs on electricity and has no backup), a stuck or jammed float switch that prevents the pump from activating, a burned-out motor from age or overwork, or a clogged discharge line that prevents water from exiting. Homeowners often discover the failure only after water has already accumulated several inches deep. Replacing a standard sump pump costs $300–$800 for the unit plus $200–$400 for professional installation, while adding a battery backup system ($200–$600) provides critical protection during power outages. Annual testing — pouring a bucket of water into the pit to confirm the pump activates — is the single best preventive measure.

Symptoms to look for
- Water accumulating on the basement floor during or after heavy rain
- The sump pump makes no sound and does not activate when the pit fills with water
- A humming or buzzing noise from the pump without it actually moving water
- The pump runs continuously without shutting off, or cycles on and off rapidly
- Visible standing water in the sump pit that is not draining down
