Repiping and Water Line Replacement in San Francisco

Repiping means putting new supply pipe in place of the old, throughout the house or along one run. When you phone, describe the pipes you have or the trouble they cause.

The plumber you hire does the work, and this page also takes in the license class, the permit and what the city says about lead.

Repiping choices

Whole-house repipe

A whole-house repipe replaces all of the supply lines, so walls and ceilings open up wherever the old pipe runs. The plumber you hire can describe the extent of it.

Partial repipe

Where only one area has given trouble, just that run of pipe is replaced and the other lines stay as they were.

A new water service line

The pipe bringing water into the building can be replaced on its own. Mention where it runs and how it is behaving.

Pipe materials

Households use both copper and PEX for water lines. The right one for your house is a choice to settle with the plumber you hire.

Lead and San Francisco’s water lines

The San Francisco Public Utilities Commission states that there is no lead in the city’s distribution lines, and that every lead service line from the distribution system was removed in the 1980s. Lead in household water mostly comes from corrosion of faucets, fixtures and solder.

That statement is about the city’s own lines. The pipes on your property are a separate question from the city’s supply.

Repipes and permits

Plumbing permit applications go to the Department of Building Inspection online, through PermitSF, and the Department tells applicants to have the work inspected before pipes are covered. Contractors authorized for Express Permits skip City staff review.

The license class

California’s C-36 classification extends to water and gas piping running from the owner’s side of the meter to the structure. The city accepts either a C-4 or a C-36 contractor for a plumbing permit.

Water showing up where it should not is covered under leak detection, while tank and tankless heaters are covered on their own water heater page. You can find the other services from the homepage.
