Slab Leak Detection in Fort Worth, TX
As specialists in residential slab leak detection in Fort Worth, we locate under-slab water leaks using acoustic, electronic, and hydrostatic pressure-testing methods — pinpointing the leak before any concrete is cut.
Finding a slab leak is a multi-step process: first, confirm a leak exists and identify which plumbing line is affected; then, pinpoint the leak's exact position beneath the concrete. Both steps require specific equipment and method knowledge — and getting them right determines how much concrete has to be disturbed, which ultimately impacts your overall slab leak detection Fort Worth cost.
Step 1: Pressure Testing to Confirm the Leak
Before any detection equipment is deployed, hydrostatic pressure testing isolates which line — hot supply, cold supply, or drain — is holding pressure and which is losing it. This prevents unnecessary detection work on a system that has no leak, and narrows the search to the specific line that is failing.
The test uses a plug and pressure gauge to pressurize each section of pipe in isolation. A line that holds pressure is intact. A line that drops pressure over a measured period has a leak somewhere along its run.

Once the leaking line is confirmed, acoustic listening equipment is placed against the floor surface and, where accessible, against pipe access points. The sound of water escaping under pressure creates a distinct frequency pattern that differs from background noise — trained technicians identify this pattern to locate the leak position.
Acoustic detection works well in residential settings where background noise is manageable. It is particularly effective for supply-line leaks where water is flowing under continuous pressure from the main supply.
Step 3: Electronic / Correlating Detection
Electronic leak correlators use two sensors placed at access points along the pipe. The system measures the time difference in acoustic wave arrival between the two sensors and uses the pipe length and material to calculate the precise position of the leak between them.
Correlating detection is especially useful for longer pipe runs and for situations where acoustic listening alone produces ambiguous results. It provides a mathematically derived location estimate that can be verified by acoustic methods before any concrete cutting begins.
What Happens After Detection
Once the leak is located — typically with an accuracy within several inches to a foot — we walk you through the options for a permanent slab leak repair service in Fort Worth. Depending on the location, pipe material, and overall condition of the system, that might mean a direct spot repair (accessing the pipe through a targeted cut in the concrete), a pipe reroute (bypassing the slab entirely with a new line), or tunneling from the exterior.
No repair work begins until you understand the options and the reasoning behind the recommendation. Review our straightforward approach to see how we help homeowners make informed decisions.
When to Call for Detection
- Your water bill has increased significantly without a change in usage
- You can hear water running when all fixtures and appliances are off
- A specific area of your floor feels warm or hot underfoot
- Flooring is showing moisture damage, warping, or buckling
- Your foundation company suspects a plumbing leak before repair work
- A water meter test shows continuous flow with all fixtures shut off
Detection FAQs
A typical detection visit takes 2–4 hours, including pressure testing and acoustic/electronic location work. Homes with larger plumbing systems, multiple possible leak areas, or difficult access points may require more time.
Both methods are reliable when used correctly. Acoustic detection is effective in quieter environments with moderate water pressure. Electronic correlators are particularly useful for precise location on longer pipe runs. In many cases both methods are used together to cross-verify the location before cutting.
Drain line detection requires a different approach since drain lines are not under constant pressure. A hydrostatic test for drain lines involves plugging the line and filling it with water to check for pressure retention. Camera inspection can also help identify drain line failures. Not all under-slab leaks are supply-line leaks — drain line problems require separate evaluation.
In rare cases — typically with very slow leaks or unusual environmental conditions — pinpoint location through acoustic methods alone is inconclusive. In these situations, a pipe reroute (which bypasses the slab entirely) is often the most practical solution because it resolves the leak without requiring a precise under-slab location.
