How many generations of pipe are there in 85375?
No — 85375 was built in layers, with four decades each holding at least a tenth of its homes. Few ZIP codes in the metro are built out over that long.
Mixed-vintage ground is the awkward kind. The failure is often at a transition fitting where an older run meets a newer one.
Each 85375 address gets read on its own. Isolate, hold at pressure, and let the result say what is down there.
Why do slab leaks show up in 85375 more than in 85379?
The two were built a generation apart: 85375 dates from 1990, 85379 in Surprise from 2006. Pipe that has been in the ground longer has had longer to corrode and perforate.
About 5 miles separates them, and rather more than that underground. One is a question about copper, with CPVC and early PEX appearing towards the end, the other about PEX and newer copper.

Straight answers
Questions we get about 85375
How old is the housing in 85375?
Most of 85375 dates from around 1990, going by the U.S. Census Bureau. It is the 2023 American Community Survey five-year estimate. About 20 percent of 85375 was built before 1980 and about 17 percent since 2000.
Does the age of 85375 tell you what the plumbing is?
In 85375, usually copper, with CPVC and early PEX appearing towards the end, which is what a 1990 build implies. That is a starting point, not a finding. Previous work changes the answer, and often has. We prove it at the property before touching a floor.
Our pressure has dropped over the last few seasons in 85375. Is that a leak?
Often, yes — on housing of this age the two go together. With a median build year of 1990, a good deal of the plumbing in 85375 is old enough for the inside of the pipe to have closed up as it corroded. That is also what eventually puts a hole in it.
Will you dig or open a floor in 85375 to find out where the leak is?
Locating comes first, and it is non-destructive. The line is isolated, held at pressure, traced and listened along. The whole purpose is to open one place rather than several. We will tell you what we found before anything is touched.
