Finding water leaks in 85022 (Phoenix)
What the Census says about the housing in 85022, and what it means for a hidden leak.
85022 covers part of Phoenix, where the typical home was built in 1986. That one number decides most of what we expect before we arrive, because a home of that vintage usually has copper, with CPVC and early PEX appearing towards the end under it.
Among the ZIP codes we cover 85022 sits in the middle for age, which in practice means more than one generation of plumbing inside the same boundary.
| What the housing in 85022 is | Figure |
|---|---|
| Median year housing was built | 1986 |
| Built before 1980 | 29 percent |
| Build era | Late-1980s through 1990s |
| Built since 2000 | 19 percent |
| Likely supply material | copper, with CPVC and early PEX appearing towards the end |
| Largest decade of building | 1980s (34 percent) |
| What tends to fail first | Mixed-material houses are the awkward ones: the failure point is often the transition fitting between two materials rather than either run itself. |
| Owner-occupied households | 51 percent |
| What we listen for | Two sounds rather than one: the escape itself, and the knock a transition fitting makes where two different materials meet |
| Single-family detached homes | 45 percent |

How many generations of pipe are there in 85022?
No — 85022 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. Where a house was part repiped, the joint between materials is the weak point.
Each 85022 address gets read on its own. Isolate, hold at pressure, and let the result say what is down there.
Does all the housing packed into 85022 get in the way?
It changes the method rather than the outcome. There is more housing per square mile in 85022 than almost anywhere we work. Dense ground is noisy ground.
Several sources put sound into the same 85022 slab. The loudest point is not automatically the leak.
So sequence matters more in 85022 than anywhere. Once the loss is proved and isolated, the noise that is left is the one that matters. See acoustic leak detection and thermal imaging.
What changes when homes in 85022 share a wall?
The first question stops being where the leak is and becomes whose line it is. Only about 45 percent of the housing in 85022 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. Finding it and owning it are different things here.
So the loss is isolated to a line under pressure before anyone assigns it. See apartment and multi-family leak detection.
The house in 85022 is a rental. Whose leak is it?
The property owner, not the resident: that pipe is part of the building. About 51 percent of 85022 is owner-occupied, which is low for the Valley. So the question comes up here more than almost anywhere we work.
The real cost in 85022 is delay. The report goes from resident to manager to owner. 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.

Straight answers
Questions we get about 85022
What is the typical age of a home in 85022?
The U.S. Census Bureau puts the median year of construction in 85022 at 1986. That figure comes from the 2023 American Community Survey five-year estimates. It places most of the housing in the late-1980s through 1990s era, which is what decides the supply material.
Does the age of 85022 tell you what the plumbing is?
Most likely copper, with CPVC and early PEX appearing towards the end, going by a median build year of 1986 in 85022. That is a starting point, not a finding. Plenty of 85022 houses have been altered since. So the line is isolated and tested under pressure before anything is opened.
Homes in 85022 share walls. How do you tell whose leak it is?
Under pressure, one line at a time, before ownership comes into it. About 55 percent of 85022 is attached or multi-unit. Water under a slab travels sideways, so damp in one home is not proof of where it came from.
Do you need to know which water utility serves 85022 before you come out?
No. The two maps do not line up, and a wrong answer about your meter helps nobody. The bill and a reading off your own meter tell us what we need.
