Sump pump not working — San Francisco, California
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.
Waarom dit veel voorkomt in San Francisco
San Francisco's Victorian and Edwardian housing stock hides original galvanized and cast-iron pipes long past their service life, prone to corrosion and low pressure. Hilly terrain complicates drainage, and seismic shifting periodically cracks pipe joints and sewer laterals.
