Repiping in San Diego, 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 San Diego 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 San Diego: what's different
Older San Diego neighborhoods like North Park and Point Loma have homes from the 1920s–1950s with galvanized supply that's often due for repiping.
Permits come from the City of San Diego Development Services Department.
Galvanized pipe corrodes from the inside, causing low pressure, rusty water and leaks at joints. Raised-foundation homes in older neighborhoods often allow lines to be run through the crawl space, which limits wall openings. Slab homes in Clairemont and Mira Mesa may need attic routing instead. A whole-house repipe usually takes two to five days.

Other San Diego conditions that affect plumbing
- Coastal corrosion: Salt air near the coast corrodes exposed metal fixtures and outdoor plumbing faster than inland.
- Hard water: Imported Colorado River water is hard, so scale shortens water heater life.
- Root-filled laterals: Older clay sewer laterals in established neighborhoods collect roots and need periodic cleaning or repair.
- Mild climate, hidden leaks: With few freezes, the biggest risks in San Diego are slow leaks that go unnoticed: slab leaks, running toilets and irrigation lines. Tiered water rates make finding them worthwhile.
