It's the technology behind most non-invasive slab leak detection — here's how it actually works.
Water escaping a pressurized pipe makes a distinct sound — often a hiss or rushing noise — that travels through pipes, soil, and concrete. Sensitive acoustic equipment is built to isolate that specific sound from background noise.
We listen at multiple points across the suspected area, comparing sound intensity to triangulate the loudest, most consistent point — which is typically the leak itself.
Without acoustic equipment, finding a slab leak means opening up concrete based on educated guesses. With it, we can often narrow the access point to a very small, specific area.
Acoustic detection works best with adequate water pressure and is sometimes combined with thermal imaging for hot water leaks, or electronic locating for tracing a pipe's exact path.
It works on most common residential pipe materials, though sound transmission can vary slightly depending on pipe material and burial depth.
No — it's a listening tool, not a machine that generates noise. The process is quiet and non-invasive.
Let's get you a real answer, not more guessing.
