Citywide emergency dispatch
For urgent plumbing help anywhere in San Francisco, call us now.
Emergency Plumber SF serves San Francisco with fast, practical help for leaks, clogs, burst pipes, sewer backups, water heater trouble, and sudden plumbing failures. San Francisco buildings are complicated: Victorians and Edwardians with century-old pipe runs, dense apartment buildings, restaurants, offices, and mixed-use properties. An emergency call here often means tight access, shared walls, aging pipes, and neighbors whose units are one leaky ceiling away from your problem.
When you call us, we focus on the problem in front of you: what's leaking, what's backing up, what can be shut off, and what needs immediate repair. We help homeowners, tenants, landlords, property managers, and business owners get clear answers without wasted time. Whether the issue is in a bathroom, kitchen, garage, basement, or commercial space, our goal is the same: stabilize the situation and restore safe plumbing function anywhere in San Francisco.
San Francisco's building stock is unusually concentrated in one era. An enormous share went up in the decades after 1906, and that shared vintage means shared failure modes. Galvanized steel supply lines corroding from the inside out, clay and cast iron laterals with separated joints, and cast iron drainage that has scaled down to half its original bore all turn up again and again across the city.
What varies is the ground underneath. The western districts sit on sand, the eastern flats on made ground, and the hills on rock. That changes how laterals settle, how quickly a leak migrates, and how much excavation a repair really involves.
The rule worth knowing anywhere in the city concerns your sewer lateral. You own the whole pipe, but the upper section from the building to the curb is yours to repair, while the lower section from curb to main is under most circumstances repaired by the SFPUC after a report through 311. A camera inspection that locates the defect relative to the curb line is therefore financial as well as diagnostic.
Corrodes internally over decades and fails as pinholes inside walls. The first one is a signal about the rest of the system.
Separated joints admit roots; cast iron scales and cracks. Both produce backups that cabling only postpones.
Upper lateral is yours, lower lateral is usually the SFPUC's after a 311 report. Locate the defect before approving work.

We know the access issues, shared systems, older piping, and fast decisions that San Francisco plumbing demands.
When you call us, we ask the right questions and help you take useful action before the technician even arrives.
Emergency plumbing, burst pipe repair, drain cleaning, sewer backup repair, water heater repair, and leak detection, all across San Francisco.
We work carefully in homes, apartments, condos, restaurants, shops, and offices throughout the city.
It depends which section failed. The upper lateral, building to the face of the curb including vent and trap, is the owner's responsibility using a licensed contractor. The lower lateral, curb to the main, is under most circumstances repaired by the SFPUC at no extra cost once you report it through 311 and their crew inspects. Get the camera locate before approving anything.
Corrosion rather than ice. Galvanized steel supply lines from the post-quake building boom corrode from the inside, narrowing and thinning until they perforate. The result is a pinhole spraying inside a wall rather than a dramatic split, which is why so many are found weeks after they started.
Often. Water heater replacement, repiping, and drain or vent alterations generally require a permit through the Department of Building Inspection. Lateral work past the trap toward the street needs a side sewer permit from San Francisco Public Works, and the contractor must hold the right licence class. Confirm who is pulling it before work starts.
Water you cannot stop, sewage backing up indoors, no water at all, a steadily leaking water heater, or the only toilet in the home blocked. A single slow drain or a dripping tap does not. After-hours labour typically runs 1.5 to 2 times standard, so the distinction is worth real money.
