Repiping in Fresno, 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 Fresno 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.

Repiping in Fresno: what's different

Older Fresno homes in the Tower District and Fig Garden still have galvanized supply that corrodes and loses pressure. Repiping restores pressure and stops repeat leaks.

Attic routing needs insulation because summer heat warms cold-water lines. Permits come from the City of Fresno.

Many Tower District homes sit on raised foundations, so plumbers can run new PEX or copper through the crawl space. Since meters were installed citywide, repeated leaks in old galvanized pipe also show up on bills, which is often what prompts a repipe.

Repiping questions in Fresno

How do I know if my Fresno home needs repiping?

Low pressure, rusty water and repeated leaks in galvanized pipe are the main signs.

Is PEX or copper better for repiping?

Both meet code in most U.S. jurisdictions. PEX costs less, needs fewer joints, and tolerates freezing better than copper. Copper lasts a long time and handles UV and high heat better. Most whole-house repipes now use PEX.

Can I live in the house during a repipe?

Usually yes. Water is shut off during the day while lines are switched over, and most plumbers restore water each evening.

How long does a whole-house repipe take?

Most single-family repipes take two to five days, depending on the number of bathrooms, the number of stories and access from a basement or crawl space.
