The original townsite is the area bounded by Greenway Road, El Mirage Road, Bell Road, and Dysart Road. It holds the city's oldest homes, which are the most likely in Surprise to have galvanized or aging copper supply lines. Rust-colored water and leaks in more than one place are the usual signs.
The Grand, formerly Sun City Grand, was built from 1996 to 2005 and has 9,802 homes. That is after the polybutylene years ended in 1995, but it overlaps the years Kitec was sold. Not every home from that era has Kitec. Checking takes a minute at the water heater.
Homes built after 2007 are the polybutylene years. A repipe here usually only makes sense after repeat slab leaks or a construction defect.
In homes built on a slab, supply lines under the concrete can fail at any age. After a second slab leak, rerouting the lines through the attic often costs less than breaking the floor again.

Replacing restricted fittings restores flow at every fixture.
An overhead reroute takes supply lines out from under the slab, so the next leak, if one ever happens, is in an attic or wall, not under your floor.
Modern PEX fittings are designed for chlorinated drinking water, and the pipe carries a printed chlorine resistance rating.
A documented replacement with a transferable warranty answers questions before a buyer's inspector raises them.
Moving supply lines out of the slab protects tile and wood floors from future leak repairs.

PEX is what we install in most Surprise repipes. For drinking water it is certified to NSF/ANSI 61. We route it to stay out of sunlight and off hot surfaces in the attic.

Copper is a good option for exposed outdoor lines and for homeowners who prefer metal. For the full comparison, see PEX vs Copper: Which Is Better for an Arizona Repipe?.

We repipe homes throughout Surprise, including the original townsite, The Grand, and the master-planned neighborhoods built since. For other plumbing work in the city, visit our Surprise plumbing page.
