Basement flooding — San Francisco, California
Basement flooding can destroy stored belongings, damage flooring and drywall, and create conditions for mold growth within 24–48 hours. Common causes include a failed sump pump, foundation cracks, clogged floor drains, or heavy rain overwhelming exterior drainage. A licensed plumber can identify the water source, clear drains, repair or install a sump pump, and recommend waterproofing solutions to prevent future flooding.
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.
