Your Plumbing Company in San Francisco, CA
San Francisco's housing stock is among the oldest in California. Victorian and Edwardian homes were built before modern plumbing standards, and many still carry galvanized steel or cast iron lines—or lead components in the oldest buildings. Add the city's steep hills, coastal salt air, and seismic movement, and you get a plumbing environment unlike anywhere else in the state.
As a plumbing company serving San Francisco, we plan around those conditions. Low pressure on a hillside may be a failing pressure-reducing valve rather than a pipe problem. A leak after a tremor may be a loosened joint. We diagnose before we recommend work, and we use methods that suit older buildings.

Plumber in San Francisco, CA: FAQs
Answers to what San Francisco homeowners ask us most.
Do you offer 24 hour emergency plumbing in San Francisco?
Yes. California Plumbing Pros is available 24/7 for urgent plumbing in San Francisco, including burst pipes, sewer backups, flooding, and no hot water. Call (800) 390-6351 any time.
Why is my San Francisco water pressure low?
Common causes include corroded galvanized supply lines, a clogged aerator or cartridge, a failing pressure-reducing valve, or the city's hilly terrain, which can create uneven pressure. We test the system to find the cause. See water line repair.
Do old San Francisco homes need repiping?
Many Victorian and Edwardian homes still have galvanized steel supply lines that corrode from the inside. If you see rusty water, low pressure, or repeat leaks, repiping with modern copper or PEX may be the lasting fix.
Do you work in San Francisco multi-unit buildings?
Yes. We help owners and residents of single-family homes, condos, and small multi-unit buildings with drains, leaks, water heaters, and fixtures.
Why do San Francisco pipes leak after earthquakes?
Even minor seismic movement can loosen joints and crack older pipes. If you notice new moisture or a pressure change after shaking, a leak detection visit can confirm whether the line was affected.
Do you offer trenchless sewer repair in San Francisco?
Yes. When the line qualifies, trenchless methods repair or replace San Francisco sewer laterals through small access points, which is valuable where excavation space is limited.
