Leak detection in 85023, Phoenix
What the Census says about the housing in 85023, and what it means for a hidden leak.
85023 covers part of Phoenix, where the typical home was built in 1985. It is the most useful thing to know about a property nobody has seen yet: build year picks the material, and here that means copper, with CPVC and early PEX appearing towards the end.
85023 is mid-table for age in our coverage, and mid-table usually means mixed.

Is a whole-home repipe the answer in 85023?
Not on the strength of a build year. Age raises the odds of a repeat failure in 85023; it does not decide anything.
Repeat failures in a short span are the thing to watch. In 85023, where 39 percent of the housing predates 1980, it comes up. But after evidence, not before it.
We would rather find one leak in 85023 and fix one leak. See slab leak repair and rerouting.
Who owns the leaking line when 85023 homes are attached?
The first question stops being where the leak is and becomes whose line it is. Only about 56 percent of the housing in 85023 is single-family detached.
Water under a slab ignores the wall above it. It surfaces at the easiest point, which may be two doors along. So the person who finds the damp may not own the pipe that lost it.
We prove which line is losing water before anyone in 85023 is blamed. It also stops the wrong floor being opened. See HOA and community leak detection.
Who pays for a leak in a rented home in 85023?
Whoever owns the building owns the water line past the meter. In 85023 only about 57 percent of occupied homes are lived in by their owner. That makes it a routine conversation rather than an awkward one.
What it changes is the clock. A resident notices damp at floor level and tells a manager. Weeks pass, and the leak is no longer near the symptom.
The finding goes in writing so it can be passed along. See property management leak detection and apartment and multi-family leak detection.
What happens to a leak in 85023 while the house is empty?
Nothing stops it, which is the problem. An empty 85023 house has nobody to notice damp or hear a hiss.
Two numbers and a date is a leak test. Write down the meter with everything off. Have someone read it again while you are away.
Seasonal and empty properties come up often enough here to have their own page. See vacant and seasonal home leak checks.

Questions we get about 85023
How old is the housing in 85023?
The U.S. Census Bureau puts the median year of construction in 85023 at 1985. It is the 2023 American Community Survey five-year estimate. About 39 percent of 85023 was built before 1980 and about 15 percent since 2000.
What kind of supply pipe is under a house in 85023?
Probably copper, with CPVC and early PEX appearing towards the end: 85023 was built around 1985. No page can tell you what is under your own slab. Plenty of 85023 houses have been altered since. So the line is isolated and tested under pressure before anything is opened.
Homes in 85023 share walls. How do you tell whose leak it is?
Under pressure, one line at a time, before ownership comes into it. Only about 56 percent of the housing in 85023 is single-family detached. Water under a slab travels sideways, so damp in one home is not proof of where it came from.
Will you dig or open a floor in 85023 to find out where the leak is?
Locating comes first, and it is non-destructive. Detection in 85023 is pressure testing, line tracing and listening, none of which breaks anything. The whole purpose is to open one place rather than several. You hear the finding before any work starts.
