What fails in 85374 is the joinery. Crimped fittings, manifold ports, and the point where a line turns or passes through the slab. That is good news: connections, not a whole run.
Nothing about a 2001 build rules a leak out. See high water bill investigation.
What happens to a leak in 85374 while the house is empty?
Nothing stops it, which is the problem. On housing of about 2001 a slow loss has as long as it wants.
The precaution costs nothing. Note the reading with the 85374 house shut off before you go. Anyone who can walk to the meter can do the second half.
Seasonal and empty properties come up often enough here to have their own page. See vacant and seasonal home leak checks.

Straight answers
Questions we get about 85374
What is the typical age of a home in 85374?
Most of 85374 dates from around 2001, going by the U.S. Census Bureau. The source is the American Community Survey, five-year estimates for 2023. It places most of the housing in the 2000s build-out, which is what decides the supply material.
What kind of supply pipe is under a house in 85374?
Probably PEX and newer copper: 85374 was built around 2001. No page can tell you what is under your own slab. A repipe, an addition or an old repair can put something else in the wall. So the line is isolated and tested under pressure before anything is opened.
Our house in 85374 is one of the newer ones. Can it still have a slab leak?
Yes, and the newness changes where rather than whether. About 52 percent of the homes in 85374 were built since 2000. The failure point is the connection. A fitting under a slab loses water exactly as fast as a split pipe does.
What should I have ready when I call about a property in 85374?
Two meter readings an hour apart with everything in the house turned off. Add a photograph of the wet patch or the pool equipment. The bills show whether the loss is new. With that we can usually narrow it before the visit to 85374.
