Water Heater Leaking — San Francisco, California
A water heater leaking from the bottom, top, or pipe connections can quickly cause significant water damage to floors, walls, and belongings. Leaks may stem from a corroded tank, a failing pressure relief valve, or loose fittings. Because water heaters involve high temperatures and potential electrical or gas connections, a licensed plumber should diagnose and repair the issue promptly.
Why this is common 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.
