Rusty water, pressure that’s dropped off, or one pinhole leak after another — when a San Francisco home’s original piping reaches the end, a repipe fixes the cause instead of chasing symptoms. Send a few details and you’ll get a straight answer from one vetted, licensed San Francisco plumber — not five companies fighting over your phone number.
Tell us the home’s age and what you’re seeing, and you’ll get a candid read on whether it’s time for a repipe or a smaller fix will do.
A repipe replaces a home’s supply piping — the lines that carry fresh water to every fixture — and in San Francisco it’s usually driven by the age of the plumbing. Many pre-war homes still run on galvanized steel that rusts closed from the inside, which is why you get low pressure and rust-tinted water. Homes piped in copper have their own issue here: the city’s soft Hetch Hetchy water is mildly aggressive to copper over decades, so once one pinhole leak shows up, others tend to follow. When a plumber is patching the same tired system over and over, a repipe is the honest fix — it resets the whole supply system rather than buying a few months at a time.
PEX or copper, and living through it
Most modern repipes use PEX, which is flexible enough to route through the tight chases, plaster walls, and raised foundations of an older San Francisco home with fewer, smaller openings — and it isn’t vulnerable to the pinhole corrosion that affects copper in soft water. Copper is still an option where it’s preferred. The real craft in a city repipe is planning the route to minimize wall damage, working around an occupied home or a stacked flat so you’re not without water for long, and pulling the proper permit and inspection through SF DBI. A plumber walks the house, gives you a straight repipe-versus-repair recommendation, and lays out how the job would actually go.

San Francisco repipe questions
How do I know if I need a repipe or just a repair?
One isolated leak is usually a repair. But when the water runs rusty, pressure has dropped throughout the house, or you’re getting repeated pinhole leaks, the piping itself is failing — and repairs just move the next leak down the line. A plumber assesses the system and gives you the honest call.
Why do copper pipes leak in San Francisco?
The city’s soft Hetch Hetchy water is mildly aggressive to copper over the years, which can lead to pinhole leaks — especially in homes piped decades ago. Once one appears, more often follow, which is why a whole-home repipe sometimes makes more sense than repairing them one at a time.
Will a repipe tear my walls apart?
Less than you’d expect when it’s planned well. PEX routes through tight spaces with fewer openings, and a good plumber maps the run to minimize wall damage and keep an occupied home — or a stacked flat — livable during the work, then handles the permit and inspection.
