Repiping in Sun City West
Sun City West was built mostly from 1978 into the late 1990s, which overlaps the years polybutylene was widely used. Many homes there have been or are being repiped with PEX, under Maricopa County permits because the community is unincorporated.

A repipe sounds like a huge project, but most single-family Valley homes are repiped in a few days while the family stays in the house. Water is off during working hours and restored most evenings.
In slab homes, the new lines run overhead: through the attic, with drops down interior walls to each fixture. Old lines in the slab are capped and abandoned, which also ends the risk of future slab leaks on those lines.

Repiping in Sun City West: local conditions
Del Webb built Sun City West from 1978 onward, the same window when polybutylene supply pipe was a common choice. Owners often find it at the water heater and under sinks, and insurers and buyers regularly ask about it when homes change hands.
Because Sun City West is unincorporated, repipe permits and inspections go through Maricopa County rather than a city. Most homes are single-story slab houses with accessible attics, which makes an overhead PEX repipe a relatively clean few-day job.
Water: EPCOR supplies water to Sun City West. Permits: Sun City West is unincorporated, so Maricopa County Planning & Development issues plumbing permits.

Frequently asked questions
Who issues repipe permits in Sun City West?
Maricopa County Planning & Development, because Sun City West is unincorporated.
PEX or copper for a Phoenix repipe?
PEX is the most common choice today: it resists scale better than older copper, has fewer joints, and handles attic routing well. Copper is still an option.
Can we live in the house during a repipe?
Usually. Water is off during working hours and restored at night on most days.
