Emergency Plumbing Services in San Francisco
When something goes wrong fast in a San Francisco home, it's usually one of these. Here's what to do first.
- Leak from an old galvanized or cast iron pipe: close the main shutoff. In a multi-unit building, tell the manager too.
- Sewage backing up: stop using water. Old laterals are a common cause. See sewer backup.
- Gas smell: leave and call the gas utility or 911 from outside. See gas smell.
For any of these, an emergency plumber can often come out to San Francisco the same day, including nights and weekends. If you smell gas, leave the building first and call the gas utility or 911 from outside.

Common Plumbing Problems in San Francisco Homes
San Francisco has some of the oldest housing of any large U.S. city: the median home was built in 1946. Victorian and Edwardian homes and pre-war apartment buildings often still have original galvanized supply pipes, cast iron drains and aging sewer laterals.
Most of the city's water comes from Hetch Hetchy Reservoir in Yosemite, filled largely by Sierra Nevada snowmelt. Freezing is rare here, so plumbing calls tend to be about old pipes, leaks, clogs and water heaters, which California requires to be strapped for earthquakes.
Galvanized Pipe in San Francisco Homes
In a city where the median home was built in 1946, galvanized steel supply pipe is still common. It rusts from the inside, so the first symptoms are usually low water pressure on upper floors and brown water after the pipes sit overnight. Spot repairs on galvanized pipe tend to move the problem down the line; repiping solves it for good.
Old Sewer Laterals
Many older San Francisco homes still have their original clay or cast iron sewer laterals. Clay joints let roots in, and cast iron cracks along the bottom. If drains back up repeatedly, a sewer camera inspection shows the condition of the line before you decide on cleaning, spot repair or trenchless repair.
Water Heater Strapping
California requires water heaters to be braced or strapped against earthquakes, so replacements must be secured to code.
What Affects Plumbing Costs in San Francisco
No plumber can quote a firm price before seeing the problem. These are the things that move the cost of plumbing work in San Francisco.
- Old pipe. Galvanized lines often can't be patched cleanly, so more pipe gets replaced.
- Access. Tight lots, shared walls and multi-story buildings make reaching pipes slower.
- Finding the problem. Leak locating and camera inspections are separate steps, but they keep the repair itself small.
- Time of day. Many companies charge an after-hours, weekend or holiday fee.
- Permits. When a job needs one, it comes from San Francisco Department of Building Inspection, and the plumber usually pulls it.
- Ask for the arrival fee before the plumber heads out, and for the repair price in writing before work starts.

Where does San Francisco's water come from?
Most of it comes from Hetch Hetchy Reservoir in Yosemite National Park, supplemented by local Bay Area reservoirs and groundwater, and delivered by the SFPUC.
How quickly can I get a plumber in San Francisco?
Often the same day, including nights and weekends, but it depends on demand and where in San Francisco you are. The plumber gives you an arrival window when you call.
