Repiping in Oakland, CA
Repiping replaces a home's water supply lines, usually because old galvanized steel has corroded or polybutylene is at risk of failing. Most repipes today use PEX, take two to five days, and are done through small wall openings rather than gutting the house.

Repiping for Oakland homes
Many homes built before the 1960s still have galvanized supply pipe, which rusts from the inside until pressure drops and the water turns brown. Some homes built between the late 1970s and mid-1990s have gray polybutylene pipe, which can fail at fittings without warning.
For the full guide, including what you can safely do before a plumber arrives, see repiping explained.

Local conditions
Repiping in Oakland: what's different
Pre-war Oakland homes often still have galvanized supply lines that corrode and lower pressure. Repiping with PEX or copper restores pressure and is often done during remodels.
Hillside homes may have long service lines too. Permits come from the City of Oakland Planning and Building Department, and EBMUD supplies the water.
Many Oakland Craftsman homes sit on raised foundations, so new lines can be routed through the crawl space with fewer wall openings. Repiping is often paired with a lateral repair when a home is sold, since both are common in pre-war homes.
