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

No single detection method works for every leak scenario. Our techs are trained on four distinct approaches and select the right tool โ or combination โ based on pipe type, building construction, and leak characteristics.
Most effective on metal pipe under slab or in concrete โ materials that conduct sound efficiently. We establish a clean acoustic baseline by briefly shutting off the house before scanning.
Active water leaks create temperature differentials on the surfaces they contact. An infrared camera shows these as color-coded heat maps, revealing the wet zone inside a wall or under a floor without any cutting. A cold water leak behind drywall appears as a spreading cool zone; a hot water leak shows the inverse.
We isolate the supply system, pressurize to operating pressure, and monitor over a timed hold period. Any pressure drop confirms active water loss from the supply side. By isolating zones โ hot side vs. cold side, section by section โ we narrow down which branch is leaking before deploying detection equipment.
For leaks that don't produce sufficient acoustic signature โ very slow leaks, polyethylene pipe, or leaks deep under concrete โ we introduce a nitrogen/hydrogen tracer gas mixture into the isolated pipe and use a calibrated gas detector at the surface to find where the gas escapes. Sensitive to concentrations far below what produces an audible acoustic signal.
Our detection service covers the full property, not just the obvious locations.
Supply lines running under or through the concrete slab fail from corrosion, shifting, or manufacturing defects โ and the leak is invisible from the surface but audible to acoustic equipment. We walk the floor on a grid pattern, map the loudest detection points, and triangulate to a specific floor location, typically within a square foot. Confirmed slab leak location is documented with marked coordinates for the repair crew.

Wall and ceiling leaks are often traced by following a visible stain to its apparent high point โ but visible damage can be several feet from the actual pipe failure due to how water travels down framing members. Thermal imaging reveals the wet zone accurately, and acoustic equipment confirms the pipe location within the wall cavity.
We also perform leak correlation surveys for longer line runs, using two listening points to triangulate the failure location mathematically.
Irrigation system leaks in main supply and lateral runs are found by isolating zones with the irrigation controller and pressure-testing each zone individually. Zone-by-zone testing narrows the failure to the smallest possible section.

We format detection reports specifically for insurance submission and provide documentation on our detection equipment and methodology to claims adjusters on request.
Commercial water loss from undetected leaks often shows up as elevated utility bills for months before physical evidence appears. We can assess a commercial building's plumbing system for suspected leaks at the property owner's or manager's request.
Finding a hidden leak isn't a single step โ it's a protocol that combines water loss confirmation, zone isolation, and targeted detection in sequence.
We start at the meter. All fixtures off, we watch the meter for 10 minutes. Movement confirms active water loss from the supply side. We also check for visible evidence โ stains, soft floors, moisture readings with a moisture meter at suspect wall surfaces.
We isolate the supply system into zones โ hot side, cold side, individual branches โ and pressure-test each to determine which is losing water. This narrows the area of active search before detection equipment is deployed.
Within the isolated zone, we deploy thermal imaging first โ 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.
You receive a written detection report including pressure test results, detection method summary, leak location relative to fixed reference points, and thermal imagery. If you want us to repair the leak, we quote immediately and can execute same-visit.

My water bill doubled over three months. Masters Plumbing Service 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 copper elbow exactly where detection said it would be. I was genuinely amazed at the precision.
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.
Commercial building with elevated water costs for six months. Masters Plumbing Service ran zone-by-zone pressure isolation across four floors, narrowed the loss to the third-floor kitchen supply branch, and located the failure with thermal imaging at a concealed valve body in the ceiling. No damage to the finished ceiling.
