Leak Detection in Phoenix, AZ

Our Phoenix work concentrates on the I-17 corridor up to the 303, where 1990s slab homes in Desert View, Tatum Ranch and Stetson Hills are producing a steady run of pinhole and slab leaks. It is some of the most predictable leak work in the Valley, if you know the housing.

Phoenix homeowners call Liberty for leak detection because we're local to the Valley, licensed, and answer the phone 24/7. We focus on north Phoenix, Deer Valley, Norterra, and the I-17 corridor up to the 303. It's a mix of 1990s and 2000s tract homes and newer master-planned builds, all on slab and all fighting the same extreme hard water. We know this stretch of the city well. We'll show you the real problem, lay out your options in plain English, and quote it fair before we start. Done right the first time.

Our Phoenix work concentrates in the north valley, where Liberty already runs daily: Deer Valley, Norterra, Tatum Ranch, and the surrounding 1990s and 2000s subdivisions off Tatum, Cave Creek, and the I-17 corridor. These neighborhoods went up fast during the build boom, almost all slab-on-grade, with copper supply lines run beneath the slab. Those copper lines are now two to three decades old, and combined with Phoenix's hard water they're hitting the age where pinhole slab leaks start showing up: a warm spot on the floor, an unexplained spike on the water bill, or the sound of running water with every fixture off.

What we see on Phoenix plumbing

  • Aging copper in 1990s slab homes prone to pinhole and slab leaks
  • High demand for water heater replacement as 2000s units age out

Leak Detection in Phoenix, FAQ

Can you find a leak without breaking anything?
Yes, that's the whole point of electronic detection. We find it first, then open exactly one spot.
My bill doubled, is it always a slab leak?
Not always. Could be an irrigation line, a running toilet, or a pool. We check the whole system.
How do you find a leak without tearing things apart?
We use acoustic listening equipment, pressure isolation testing, thermal imaging, and sometimes tracer gas to pin down the exact spot first. The whole point is to open one small, correct spot instead of tearing into walls or slab while we hunt.
How can I tell if I have a hidden leak?
Watch for a water bill that jumps with no change in how you're using it, a meter that moves when everything's off, a warm spot on the floor, a musty smell, or buckling paint and baseboards. Those indirect signs are how slab and in-wall leaks give themselves away.
Is there a leak test I can do myself?
Yes. Shut off every fixture and appliance, then look at whether the water meter's flow indicator is still moving. If it is, you've got a leak. Shut the valve where water comes into the house and check again, and that tells you whether it's inside the home or outside in the irrigation.
Could my high water bill be the pool or sprinklers, not the house?
Very possibly. In the Valley, pools and big drip irrigation setups are common sources of mystery high bills and water loss. Detection isolates which system is leaking first, so you're not opening a slab when a cracked irrigation line out in the yard is the real problem.
How urgent is chasing down a hidden leak?
Don't wait. A silent leak under a slab or in a wall wastes water around the clock, runs up your bill, and can grow mold or undermine the foundation. The sooner we find it, the smaller and cheaper the repair and the less collateral damage you're left with.
Do you cover all of Phoenix or just the north side?
We focus on north Phoenix, where we're already working every day: Deer Valley, Norterra, Tatum Ranch, and the neighborhoods along the I-17 and Cave Creek corridors. Staying concentrated in the north valley means faster response and crews who know the housing stock and the water in these specific subdivisions.
