What a slab leak looks like
Your questions answered
Do newer Maricopa homes with plastic lines leak?
They can. In Maricopa's newer homes leaks are less often pinholes and more often fittings or damage during construction, and the technician tests accordingly.
Can you work in a Maricopa townhome with shared walls?
Yes. Associations are common in Maricopa and shared walls mean access needs planning, so tell us about the layout when you call.
What should I tell the dispatcher when calling about Maricopa?
The year the house was built, whether there is a pool, and the meter result with and without the irrigation controller. Those three answers usually shape the first visit in Maricopa.
What is a pinhole leak in a Maricopa home?
A tiny break in the wall of a pipe that weeps slowly. It is less typical in Maricopa's newer plastic lines, which tend to leak at fittings instead.
What if my Maricopa meter keeps moving with everything off?
Water is leaving somewhere on your side. With irrigation and the pool ruled out, the service line or a line under the house is the likely place. With about 58,143 residents (2020 Census), Maricopa is a regular part of our Pinal County calls.
Can a break in a yard line look like a slab leak?
Yes. A line from the meter across the yard can leak without any wet spot indoors. It is ruled out early.
What next if my Maricopa pool and irrigation check out?
Then attention turns to the service line and the lines under the Maricopa house, and a technician can locate the leak. Maricopa homes are mostly newer, so fittings are a common place to look.

The order of elimination
A high bill or a moving meter has several possible sources in an Arizona home: a slab leak, a pool auto-fill, a drip zone, a buried yard line, an evaporative cooler or a toilet that runs on. A technician works through these in order rather than assuming the slab.
Three readings settle most of it: a quiet house, irrigation switched off and a day on the pool mark. If the meter still moves, the buried lines are next.
Isolating hot, cold and outdoor lines
The outdoor line, the cold supply and the hot supply are each closed and tested, so the leak is tied to one of them.
Meter check with everything off
Shut every tap, confirm the dishwasher and washer are idle, then find the leak indicator on the meter, usually a small dial or triangle, and watch it for five minutes.
When repiping becomes the conversation
Repiping is presented as an option with reasons, not as the default.
Sort out where the water goes
Work through the steps in sequence and note each result for the dispatcher.
How the technician finds it
