Leak detection in Gilbert
Still legally a town, and one of the youngest large places in the Valley — which puts nearly all of its buried pipe in the same generation.
Gilbert’s housing is young and consistent, and its lots are generous. Both facts matter. Young housing means PEX and newer copper underneath, which rarely fails along its length but does fail at fittings and manifolds. Generous lots mean long private runs: more buried supply line, more irrigation, more distance between the meter and anything anyone would notice.
Put together, that produces the most common Gilbert call we get, which is not a flood at all. It is a bill that climbed, or a meter that will not sit still, with a house that is completely dry inside.
Gilbert is still legally a town, despite being larger than most Arizona cities, and it is one of the newest large places in the Valley: a median year of construction of 2003, with well over half the housing built since 2000, only a sliver predating 1980, and a high single-family share.

Long runs, quiet losses
The service line from the meter to the house is the piece of plumbing homeowners think about least and own most completely. On a large Gilbert lot it can be a substantial run of buried pipe, and when it weeps there is nothing above it to get wet — no ceiling, no wall, no floor. The only witness is the meter.
Irrigation is the other silent one. Valves, lateral joints and drip runs all fail underground, and desert landscaping hides the result: moisture under decorative rock is invisible until the colour of the stone changes. On City of Phoenix Water Services’ own reckoning the larger part of household water is used outdoors, so the odds sit outside before they sit inside.

What fails in a house built in the 2000s
Fittings, manifolds and the elbows where a line turns up out of the slab. That is genuinely most of it. Newer pipe does not corrode along its length the way mid-century galvanized did, so the search is for a point rather than a stretch, which rewards isolating zones and pressure-testing them one at a time.
When a Gilbert slab leak is real, it is usually small: a warm patch of floor, a faint hiss in a silent house, a meter creeping overnight. We prove the loss, trace the line, listen along it and confirm with thermal imaging before anybody discusses concrete — and a post-tension slab is not cut until the requirements around cutting have been respected.

Where to start before you call anyone
Ten Valley cities put out the Smart Home Water Guide together, through the Arizona Municipal Water Users Association, and Gilbert is one of them. It walks a homeowner through finding a household leak a step at a time, it is written for householders rather than for the trade, and working through it is worth the time.
The two steps from it that save us the most time: read the meter with every water-using thing switched off, and if the pool is a suspect, run a bucket test with the auto-fill turned off, once with the equipment on and once with it off. Send us those two answers and we arrive already knowing which half of the property to work.

Questions we get in Gilbert
Nothing is wet anywhere but the bill went up. Where would you look in Gilbert?
Outside, and probably underground. Gilbert lots are large, so the private service line between the meter and the house is a long run that nothing sits above — a weep there produces no visible damage at all. Irrigation is the other candidate, and desert landscaping hides a wet patch under decorative rock until the stone changes colour.
My house is from the early 2000s. What actually fails at that age?
Connections. With a median build year of 2003, most Gilbert housing is PEX or newer copper, which almost never fails along a run. It fails at fittings, manifolds and the elbows coming up out of the slab, so we isolate and pressure-test zones rather than hunting for a corroded length of pipe.
Is there anything Gilbert publishes that would help me check first?
Yes. The Smart Home Water Guide is put out by ten Valley cities together, Gilbert among them, through the Arizona Municipal Water Users Association, and it walks a homeowner through finding a household leak a step at a time. The meter check and the pool bucket test in it are the two things worth doing before you call anybody.

Read the meter with everything off and send us the photo. On a large lot that one reading narrows the search enormously.
