Sump pump not working — Chicago, Illinois
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.
Why this is common in Chicago
Chicago's extreme winter temperatures routinely cause frozen and burst pipes, especially in older bungalows and greystone buildings. The city's combined sewer system leads to basement flooding during heavy rains, and many homes still have lead service lines requiring replacement.
