A slab leak is a break in a water or sewer line running underneath your home's concrete foundation. Because the pipe is buried under the slab, you can't see it directly, which is why most slab leaks are caught by their side effects rather than the leak itself.
Why Slab Leaks Are Common in Stillwater
Most of Stillwater sits on Permian red clay, soil that swells when it rains and shrinks when it dries out. That constant movement puts stress on rigid pipe joints running under a slab, more than you'd see in sandier or more stable soil. It's a big part of why slab leaks show up here more than homeowners moving from other states tend to expect.
Signs You Might Have a Slab Leak
- Unexplained water bill increase: A jump with no obvious cause is the most common first clue.
- A warm spot on the floor: If the leaking line carries hot water, you may notice one area of flooring feels warmer than the rest.
- The sound of running water: Audible even when every fixture in the house is off.
- Damp carpet or buckling flooring: Water finding its way up through the slab over time.
- Mold or a musty smell: Moisture trapped under flooring feeds mold growth you may smell before you see.
The Water Meter Test
This is the simplest way to confirm a leak exists before calling anyone. Turn off every fixture and appliance that uses water, then check your water meter. Note the reading, wait 20 to 30 minutes without using any water, and check again. If the reading moved, water is leaving your system somewhere, which is either a slab leak or a leak elsewhere in the line.
How Professionals Confirm and Locate It
A meter test tells you there's a leak. It doesn't tell you where. Professional detection narrows that down using:
- Pressure testing: Isolates the plumbing system to measure how fast pressure drops, which helps confirm the leak's general severity.
- Acoustic listening equipment: Ground microphones pick up the sound of pressurized water escaping, even through a concrete slab.
- Thermal imaging: An infrared camera reads temperature differences at the floor surface caused by water below it, especially effective on hot water line leaks.

What Happens After It's Located
Once a slab leak is marked, repair options usually include a spot repair at the exact location, a reroute that runs a new line above the slab instead of through it, or in some cases a full re-pipe. Which one makes sense depends on the pipe's age, material, and how accessible the marked spot is.
