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 Waikoloa 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.
Pressurized supply line leaks create a low-frequency sound as water escapes the pipe and contacts surrounding soil or structure. Our amplified listening devices filter background noise so we can triangulate the loudest point โ often to within 6โ12 inches of the actual break, through concrete slabs or behind drywall.
Particularly effective inside insulated wall cavities and for finding the extent of moisture spread beyond the immediate leak point โ telling us not just where the pipe is failing but how far the moisture has already traveled.
Pressure decay testing is the standard by which we confirm a leak is present before committing detection equipment time. A rapid drop vs. a slow one also indicates the approximate size of the escape point.
Tracer gas is the method of last resort for the most challenging cases. It adds setup time but finds leaks that acoustic and thermal methods alone can't conclusively locate.
Our detection service covers the full property, not just the obvious locations.
Thermal imaging supplements acoustic detection for slab leaks, identifying the thermal anomaly that appears on the floor surface as water migrates through the concrete.

We document the thermal anomaly, mark the approximate pipe location, and recommend a minimal access cut rather than a wide wall opening โ typically saving hundreds in drywall repair costs.
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.

Insurance claims for water damage from hidden leaks typically require documentation that the leak was not visible or detectable without specialized equipment. Our detection report includes: pressure test results confirming active water loss, detection method used, thermal imagery or acoustic mapping showing leak location, and technician certification information.
Commercial buildings have complex pipe networks where a supply or drain leak can go undetected through multiple floors before surfacing. We approach commercial detection systematically โ zone-by-zone pressure isolation, thermal scan of suspect surfaces, and acoustic confirmation.
Here's exactly how a Masters Plumbing Service leak detection call plays out in Waikoloa, HI.
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.
Insurance-formatted reports are available for claims submission at the same standard โ no additional cost.

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.
Our detection technicians are equipped with acoustic, thermal, and tracer gas tools for the full range of leak scenarios found in Waikoloa, HI homes and commercial properties.
