Leak Detection Serving Gilbert, AZ
Leak detection in Gilbert starts with a simple question: is water leaving your pipes when nothing is on? If your meter keeps moving or your bill keeps climbing, we narrow down where the water is going before anyone opens a floor or a wall.
Pipeliners serves Gilbert homeowners from our Mesa office. We locate leaks in the water lines that feed your home, including lines under the slab.
What Does Leak Detection in Gilbert Involve?
Leak detection in Gilbert narrows down where a pressurized water line is losing water, often under the slab or inside a wall. We confirm the leak with a pressure test, then trace it with acoustic listening and thermal imaging. It locates the leak. It does not repair it, so the repair is a separate step.
Signs of a Hidden Leak in a Gilbert Home
- Your water bill went up and your habits did not change.
- The leak indicator on your meter moves with every tap, appliance and sprinkler off.
- One part of a tile floor feels warm under bare feet.
- You hear water running in a wall or under the floor when the house is quiet.
- A baseboard is swelling, or carpet near an inside wall is damp.
- Hot water takes longer to arrive, or the water heater seems to run more than usual.
Any one of these is worth a meter check. A running toilet, irrigation or a water softener can cause some of them too, so rule those out first.
How We Locate Slab and Water Line Leaks
Each tool answers a different question. We use them together:
Pressure Test
Tells us if a line is losing water, and whether it is the hot side or the cold side.
Acoustic Listening
Picks up the sound of water escaping under pressure, so we can follow it to one spot.
Thermal Imaging
Can show a warm pattern from a leaking hot water line through the floor. We use it with the other tools, not on its own.
A Marked Spot
We mark the leak as closely as the tools allow, so any opening stays small.
This page is about the water lines that feed your home, which are under pressure. For pools and sprinklers, start with the Town’s leak videos below.
If you smell sewage or the wet spot shows up after a flush, the problem may be a drain line instead. That is found with a camera. See trenchless drain pipe repair.

OUR PROCESS
How a Gilbert Leak Detection Visit Works
Four simple steps, from the meter to your options.


- Check the meter. We confirm water is moving through the meter with the fixtures off.
- Test the lines. A pressure test shows which line is losing water.
- Find the spot. Acoustic and thermal tools narrow it to one place, and we mark it.
- Explain the options. We tell you what we found and what can fix it before any repair starts.

Checking for a Leak in Gilbert
The Town of Gilbert has a six-part video series for checking your home for leaks. It starts with the meter, then checks pools, irrigation, the service line, indoor fixtures and water softener or reverse osmosis systems. Run through it first. It can rule out a running toilet or a broken sprinkler before you call anyone.
Read your meter. Gilbert homes have one of four meter types. On a Sensus meter, the red dial with a black line is the leak indicator, and one full turn means 1/10 of a gallon went through. If it turns with nothing on, water is leaving the system. (Source: Town of Gilbert, How to Find & Fix Leaks.)
If the meter still moves after those checks and you cannot find the cause, the leak may be hidden in a wall or under the floor. That is when to call us. The Town also offers residents a water efficiency checkup.

After the Leak Is Found
For pinhole leaks in copper lines that are still sound, we can restore the pipe from the inside with ePIPE restoration, usually without opening the floor. The pipe is cleaned, then coated inside with an epoxy that is NSF/ANSI 61 certified for drinking water.
If a line is split, crushed or too damaged to coat, we tell you that it needs to be replaced. Read what causes pinhole leaks in copper pipes.

Leak Detection Questions From Gilbert Homeowners
How much should leak detection cost?
It depends on how many lines need testing, how easy they are to reach, whether the leak is under the slab or in a wall and how long it takes to narrow down. We explain the cost before we start.
How do I check my Gilbert water meter for a leak?
Turn off every tap, appliance and sprinkler. Find the meter box, open the lid and watch the leak indicator or the last digit for a few minutes. If it moves with nothing on, water is leaving the system. The Town of Gilbert’s leak videos show each meter type.
Can you find a slab leak without breaking the floor?
Yes. Slab leak detection is done from above the floor with pressure, acoustic and thermal tools. The floor is opened only at the marked spot, and only if the repair needs it.
What happens after the leak is found?
We explain what we found and the options. For copper lines that are still sound, ePIPE can restore the pipe from the inside, usually without opening the floor. If the pipe is too damaged to restore, we tell you.
What if the leak is a drain, not a water line?
Drain lines are not under pressure, so the tools above do not find them. A sewer smell or a wet spot after flushing points to a drain. We check drains with a camera instead.
