Discolored or rusty water — San Francisco, California
Brown, yellow, or rusty water coming from your taps can indicate corroding pipes, sediment buildup in the water heater, or issues with the municipal supply. While sometimes temporary after utility work, persistent discoloration may signal galvanized pipes deteriorating from the inside — a problem that worsens over time and can affect water quality and pressure. A plumber can diagnose whether the issue is in your home's plumbing or the supply side and recommend repair or repiping.
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.
