Does your Keller home need slab leak detection?
- Water bill jumped with no change in use
- Meter keeps moving with everything off
- Warm spot on tile, wood or carpet
- Running-water sound when nothing is on
- Water heater runs constantly
- Damp carpet, cupped wood, musty smell
- Sewer smell or slow drains
- New cracks or sticking doors
Our Keller home's water bill went up, but only in winter when we don't water the lawn. What does that tell us?
That is a useful clue. In winter, irrigation isn't hiding anything, so a higher bill points to a leak inside the system. Do the meter test with every fixture off; if the meter moves, the house lines or yard line are losing water.
Check for a slab leak in Keller before you call
Five minutes of setup and a two-hour wait will tell you whether your Keller home is losing water.
- Turn everything off. Faucets, dishwasher, washer, ice maker, sprinklers and pool fill.
- Find your meter. It is usually in a box near the street. Read the number or take a photo.
- Wait one to two hours. Use no water at all during that time.
- Read it again. If the number moved, or the small leak indicator is spinning, water is escaping.
- Narrow it down. Close the house shut-off. If the meter keeps moving, the leak is in the yard line; if it stops, it is inside, possibly under the slab.

Why slab leaks happen in Keller
Keller sits on North Texas clay that swells after rain and shrinks through long summers, and every slab in town moves a little with it. Pipes cast into or laid under the concrete flex with each cycle.
Most of Keller was built during its fast growth in the 1990s and 2000s. Copper supply lines in those homes are now 20 to 30 years old, and larger lots mean longer service lines from the meter to the house.
Serving homes across Keller, including neighborhoods near Keller Town Center, Bear Creek Park, Keller Pointe.
Keller lots are big. How do I know if the leak is in the long line from the meter or under the slab?
Close the main shut-off where the line enters the house and watch the meter. If it still moves, the leak is in the yard line between the meter and the house. If it stops, the leak is inside, possibly under the slab.
What is under the slab in Keller homes
Across Keller: 1960s–80s brick ranches with cast-iron drains, plus larger 1980s–2000s homes with copper supply lines. Knowing what pipe is under your floor tells the plumber which slab leak detection method will work best.
Copper supply lines
Common in homes built from the 1960s through the early 2000s. Copper wears where it rubs against concrete or gravel, and pinhole leaks show up as homes pass 25–40 years old. Acoustic listening finds them well.
Cast-iron drains
Standard in homes built before about 1980. Cast iron rusts from the inside and cracks as the slab moves. Drain leaks never show on the water meter, so a hydrostatic test and camera inspection are used.
Polybutylene
Gray plastic pipe installed from about 1978 to 1995. It is known for failing at fittings. Tracer gas and pressure testing are often the best ways to locate leaks in it.
PEX and newer plastic
Used in most homes built since the 2000s, often run from a manifold. PEX leaks are usually at fittings or where the pipe was nicked during construction. Each run can be pressure-tested from the manifold.
Our slab leak detection process in Keller
The same nine steps on every job, so you know what’s happening and why. Read the full process →
Listen and look first
The plumber hears what you've noticed and walks the home to look for clues.
Rule out the easy causes
Toilets, faucets, irrigation, the water heater and the AC drain are checked so you don't pay to search for the wrong leak.
Confirm the leak with the meter and a pressure test
A meter test and a pressure test prove water is escaping from the plumbing.
Isolate the leaking line
Hot, cold and branch lines are separated so the search focuses on the one that's leaking.
Test the drains, if needed
Drain leaks don't show on the meter, so they get their own hydrostatic test and camera check.
Trace the pipe's route
An electronic locator maps where the leaking line actually runs under the floor.
Pinpoint the exact spot
Acoustic listening, thermal imaging and tracer gas find where the water is escaping, and two methods must agree.
Scan the slab and mark the leak
The slab is checked for steel tendons and rebar, and the leak is marked on the floor.
Get your written report
You receive the leak's location, the line, the readings and photos in writing.

Your Keller slab leak detection visit, start to finish
Keller slab leak detection follows the same careful path on every job, but the details depend on your home. A licensed plumber who serves Tarrant County arrives with pressure gauges, an acoustic ground microphone, a thermal camera and, when needed, tracer gas equipment.
Before any listening starts, the plumber rules out toilets, faucets, irrigation and the water heater, then pressure-tests the system. Closing the cold inlet at the water heater shows whether the leak is on the hot or cold side.
Next, the line is traced and the slab is scanned. Acoustic listening finds the point where escaping water is loudest, thermal imaging confirms hot-water leaks, and tracer gas handles the quietest leaks. Two readings must agree before the spot is marked.
Before the plumber leaves, you get a written report with the leaking line, the exact location, the readings and photos. Keep it for your insurer, your water utility’s leak credit and whichever licensed plumber you choose for the repair.

| Detection tools | Acoustic ground mics, thermal imaging, tracer gas, line tracing | Varies; often a pressure test and visual inspection |
| Locating the leak | Pinpointed before any concrete is opened | May open the floor in more than one place to search |
| Drain leaks under slab | Hydrostatic, isolation test and camera find the broken section | May recommend replacing the whole drain system |
| After the leak is found | Exact spot marked and documented; you choose who fixes it | Often moves straight into its own repair or repipe |
| Paperwork | Written report with photos for insurance and water credits | Usually an invoice only |

Insurance and slab leaks in Texas
Coverage depends on your policy and the cause. The Texas Department of Insurance has long said the standard HO-B policy covers damage to the dwelling, including the foundation, from an accidental discharge of water from a plumbing system. Many policies still exclude wear and tear, the pipe itself, and mold.
What helps your claim: shut off the water, protect your belongings, and get the leak documented by a licensed plumber before the adjuster visits.
Ask for a leak credit
Many Texas cities and MUDs credit part of the water lost to a hidden leak once it’s repaired. Most want a paid plumber’s invoice and a request within a set number of days, and allow one credit a year.
Keep your invoice, and call your utility soon after the repair to ask about its rules and deadline.
Questions about slab leaks in Keller?
Still not sure if you have a slab leak? Call and describe what you’re seeing. A licensed plumber will tell you whether it’s worth a visit.
Call (833) 841-0340Our Keller home was built in 1998. Should we expect pinhole leaks soon?
Copper of that age has had about 25 years of movement and abrasion against the slab, so pinholes become more likely, especially on hot lines. There is no need to act on age alone, but a warm floor or rising bill deserves a test.
Can a Keller home's sprinkler backflow device leak and look like a slab leak?
Yes. A backflow preventer can drip or leak steadily, and it is on the irrigation side of the meter. Close the irrigation supply and redo the meter test; if the meter stops, check the backflow device.
Can a Keller pool's auto-fill hide a slab leak?
It can make the bill harder to read, because the auto-fill adds water every day. Switch it off before doing the meter test so the pool doesn't mask, or mimic, a leak in the house.
Is the hot-water heater in our Keller garage a clue to where a leak might be?
Yes. Hot lines leave the garage and run under the slab to the bathrooms and kitchen, so a hot-side leak often sits somewhere along that path. A warm strip of floor between the garage and those rooms is a classic sign.
Will slab leak detection in Keller leave holes in our floor?
No. Detection uses pressure, sound, heat and tracer gas from the surface. The leak is marked with tape, and nothing is opened unless you choose a repair afterward.
Do Keller homes need a drain test as well as a water line test?
Only if there are drain symptoms such as a sewer smell, slow drains or dampness near a bathroom with a normal meter test. Drain leaks never show on the meter, so they need a hydrostatic test.
