Acoustic & Electronic Leak Detection Beneath Concrete
Before any concrete is cut or pipe is rerouted, you must know the exact location and nature of the leak. Guessing where a leak originated can lead to unnecessary holes in expensive hardwood or custom tile flooring. At Ever Leak Plumbing Washington, our under-slab leak detection process relies on military-grade acoustic frequencies and advanced physics to locate pressurized leaks to within inches.
Our Advanced Leak Detection Technologies
We employ a multi-layered diagnostic system tailored specifically for Washington homes with concrete slab foundations:
- Digital Acoustic Ground Microphones: Pressurized water escaping through a pinhole in copper or PEX creates a distinctive high-frequency hiss or low rumble. Our acoustic listening discs filter out ambient street and household noise to isolate that precise sound wave beneath 4 to 8 inches of concrete.
- Helium & Nitrogen Tracer Gas: For extremely small pinhole leaks or noisy residential environments, we evacuate the water line and inject a safe, non-toxic, non-flammable mixture of helium and nitrogen. Because helium molecules are lighter than air, they rise directly through concrete pores and gravel, where our sensitive "sniffer" sensors detect them at the exact fracture point.
- Electromagnetic Pipe Locators: We transmit a radio-frequency signal down the copper pipe to map its subterranean pathway precisely, revealing corners, tees, and manifolds hidden under the foundation.
- Digital Manometer Pressure Decay Testing: Sensitive digital gauges monitor pressure retention down to 0.1 PSI to verify whether the cold water, hot water, or irrigation supply line is leaking.
What to Expect During Your Detection Service
- Initial System Audit: We check your water meter, test static house water pressure, and inspect all accessible fixtures, toilets, and water heaters to rule out surface leaks.
- Line Isolation: The hot and cold domestic water loops are isolated to determine which specific circuit is losing pressure.
- Sub-Slab Acoustic Sweep: Our technician walks the foundation perimeter and interior rooms with the electronic listening disc, recording decibel spikes.
- Marking & Diagnostic Report: We clearly mark the leak location on your floor with safe blue painter's tape and provide you with an itemized technical report outlining repair options.
100% Non-Invasive Guarantee
Our diagnostic team will never cut into your concrete foundation or tear up flooring merely to "find" the leak. We pinpoint the problem before a single tool touches your floor.

Frequently Asked Questions: Under-Slab Detection
Under typical residential conditions with standard concrete slabs, our acoustic listening sensors locate the leak within a 6-inch to 12-inch radius, ensuring that any necessary spot repair access is minimal and precise.
Most single-family residential leak detections take between 1.5 and 2.5 hours to thoroughly isolate the line, map the piping path, and pinpoint the leak location.
