A water bill that jumped 30% with no change in usage. A ceiling stain that keeps reappearing after patches. A soft spot in the flooring with no visible source. These are signs of a hidden leak that's been running long enough to cause structural damage — and every day it runs is money lost and damage accumulating. Masters Plumbing Service uses acoustic ground microphones, thermal imaging cameras, and precision pressure testing in Bowerston, OH to locate leaks without speculative demolition.

No single detection method works for every leak scenario. Our technicians are trained on four distinct approaches and select the right tool — or combination of tools — based on the pipe type, building construction, and leak characteristics.
Acoustic detection is most effective on metal pipe (copper, cast iron) under slab or in concrete — materials that conduct sound efficiently. It works in quiet environments and requires shutting off the house briefly to establish a clean acoustic baseline.
Thermal imaging is particularly effective inside insulated wall cavities and for finding the extent of moisture spread beyond the immediate leak point. It tells us not just where the pipe is failing but how far the moisture has already traveled.
We isolate the supply system, pressurize it to operating pressure, and monitor pressure over a timed hold period. Any pressure drop confirms active water loss from the supply side. By isolating zones — hot side vs. cold side, section by section — we narrow down which branch of the supply system is leaking before the detection phase begins.
Tracer gas detection is the method of last resort for the most challenging cases — it adds cost and setup time. We use it when acoustic and thermal methods haven't produced a definitive location and the evidence clearly supports an active leak.
Our detection service covers the full property, not just the obvious locations.
Confirmed slab leak location is documented with a marked point on the floor and provided to you in the written detection report, with coordinates relative to fixed reference points for the repair crew.
We document the thermal anomaly, mark the approximate pipe location, and recommend a minimal access cut rather than a wide wall opening.
We mark the ground above the detected leak location so the repair crew opens only the section they need to.
Pool plumbing — suction and return lines buried between the equipment pad and the pool shell — can develop leaks at fittings or in the pipe body that appear as unexplained water loss. We pressure-test the pool plumbing circuit, isolate the return and suction lines separately, and use acoustic detection to find which line and where.
Multi-story buildings, commercial kitchens, retail spaces, and industrial properties have complex pipe networks where a supply or drain leak can go undetected through multiple floors before surfacing. We approach commercial detection systematically — zone by zone pressure isolation, thermal scan of suspect surfaces, and acoustic confirmation.
We format detection reports specifically for insurance submission and can provide documentation on our detection equipment and methodology to claims adjusters on request.
Here's exactly how a Masters Plumbing Service leak detection call plays out.
This step confirms we're looking for a real leak rather than meter error or a normal appliance cycling.
We isolate the supply system into zones — hot side, cold side, and if possible, individual branches — and pressure-test each zone to determine which branch is losing water. This narrows the area of active search significantly before detection equipment is deployed.
Within the isolated zone, we deploy thermal imaging first — scanning walls, floors, and ceilings for moisture anomalies. Then acoustic equipment confirms the specific pipe location and narrows it to the tightest possible point. Tracer gas is added if acoustic results aren't conclusive.
Insurance claims: the report is formatted to support a claim for water damage from a concealed leak. We can provide supplemental documentation on request.

My water bill doubled over three months with no change in usage. Masters Plumbing Service came out, confirmed the meter was moving with everything off, isolated the cold supply to the kitchen as the failing branch, and used the acoustic device on the slab to pinpoint a location 4 feet from the outside wall under the kitchen floor. The repair crew opened a 10-inch circle in the tile, found a pinhole in a copper elbow exactly where detection said it would be. I was skeptical acoustic detection was that precise — it was.
Our insurance company required professional leak detection documentation before approving the claim. Masters Plumbing Service's written report with pressure test data and thermal imagery was exactly what the adjuster needed. Claim approved. The detection cost was covered as part of the claim.
Pool was losing 2 inches of water per day — more than evaporation could explain. Masters Plumbing Service pressure-tested the plumbing circuit, isolated the issue to the return line, and ran acoustic detection along the line path to find the failure at a union fitting under the decking. Repair required pulling one deck board instead of the exploratory digging another company had proposed. Excellent, focused work.
