Our Detection Methods

How We Find Hidden Leaks Without Guessing

A pressure test tells us a leak exists and how much water is escaping. Detection equipment tells us precisely where.

🎙️

Acoustic Ground Microphone

Pressurized supply line leaks create a distinctive low-frequency sound as water escapes the pipe and contacts surrounding soil or structure. Our acoustic listening devices amplify this signal, filtered for background noise, so we can walk a grid pattern and triangulate the loudest point — often to within 6–12 inches of the actual break.

🌡️

Infrared Thermal Camera

Active water leaks — hot or cold — create a temperature differential on the surfaces they contact. An infrared camera shows these differentials 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 blue-gray cool zone; a hot water leak shows the inverse.

📉

Pressure Decay Testing

Pressure decay testing is the standard by which we confirm a leak is present before committing detection equipment time. It also tells us approximately how significant the leak is — a rapid pressure drop vs. a slow one indicates the size of the escape point.

💨

Tracer Gas Detection

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.

What We Locate

Every Leak Detection Scenario We Handle in San Ramon, CA

Our detection service covers the full property, not just the obvious locations.

Under Slab

Slab Leak Detection

Supply lines run under or through the concrete slab in most slab-on-grade homes. When these lines fail — from corrosion, shifting, or manufacturing defects — 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.

In-Wall

In-Wall & Ceiling Leak Detection

Wall and ceiling leaks are often traced by following a visible stain to its apparent high point — but the 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.

Water Main

Underground Supply Line Detection

We mark the ground above the detected leak location so the repair crew opens only the section they need to.

Pool & Irrigation

Pool Line & Irrigation Leak Detection

Irrigation system leaks in main supply lines 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.

Commercial

Commercial Property Leak Detection

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 property manager's request.

Documentation

Leak Detection Report for Insurance

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.

Our Process

How Our Leak Detection Process Works in San Ramon, CA

Here's exactly how a Masters Plumbing Service leak detection call plays out.

Initial Water Loss Confirmation

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 any visible evidence — water stains, soft floors, moisture readings with a moisture meter at suspect wall surfaces.

Zone Isolation & Pressure Decay

Zone isolation is the step that turns "there's a leak somewhere in the house" into "the leak is on the hot side supply, between the water heater and the master bath."

Detection Equipment Deployment

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.

Written Report & Repair Options

You receive a written detection report including pressure test results, detection method summary, leak location (described relative to fixed reference points), and thermal imagery. If you want us to repair the leak, we quote the repair and execute immediately. If you have your own plumber, the report gives them everything they need.

Customer Reviews

San Ramon, CA Homeowners Who Found Their Leak with Masters Plumbing Service

★★★★★

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.

— C. Thornton, San Ramon

★★★★★

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.

— B. Osei, San Ramon, CA

★★★★★

Commercial building where water costs were running 40% above baseline for six months. Masters Plumbing Service ran a systematic 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.

Common Questions

Leak Detection Questions from San Ramon, CA Property Owners

Secondary indicators: water stains appearing or recurring in the same area without an obvious source; mold or mildew smell in rooms without a plumbing fixture; soft or discolored flooring; consistent sound of running water in walls when all fixtures are off.

The repair itself requires physical pipe access, which typically means a small, targeted opening. But that's a completely different proposition from opening large wall sections while searching for an unknown leak location.

For leaks in plastic pipe, low-pressure situations, or high-noise environments, accuracy may be lower and tracer gas becomes the preferred supplemental method.

We can provide supplemental information to claims adjusters on request, including equipment calibration records and a technical description of the detection methodology used.

A standard residential leak detection — confirming water loss, isolating the failing zone, and deploying detection equipment to locate the failure — typically takes 1.5–2.5 hours. More complex scenarios (multi-zone commercial, large properties, very slow leaks requiring tracer gas) can run 3–4 hours.

The repair quote is given before any wall or floor is opened. You know the full cost of detection + repair before anything is cut.
