Sewer gas smell in house — San Francisco, California
A rotten-egg or sulfur smell inside your home usually means sewer gas is escaping through a dried-out trap, cracked drain pipe, or failing wax ring on a toilet. Sewer gas contains methane and hydrogen sulfide, which are unpleasant and potentially hazardous in high concentrations. A licensed plumber can locate the source, restore trap seals, replace damaged components, and ensure your venting system is working properly.
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.
