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

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.

🌡️

Infrared Thermal Camera

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.

📉

Pressure Decay Testing

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

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

Leak Detection for Walls, Slabs, Pools & Irrigation in Nicasio

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

Under Slab

Slab Leak Detection

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.

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

Supply lines between the meter and the structure run underground and are vulnerable to corrosion, ground movement, and tree root damage. A main supply line leak shows as unusually high meter usage with all interior fixtures off, sometimes with wet ground or sinkholes along the line path. Acoustic detection locates the failure in the buried line precisely enough to minimize excavation footprint.

Pool & Irrigation

Pool Line & Irrigation Leak Detection

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.

Commercial

Commercial Property Leak Detection

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.

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 Nicasio, 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

We document findings with thermal images and note detection readings at multiple grid points to triangulate the strongest signal.

Written Report & Repair Options

Insurance claims: the report is formatted to support a claim for water damage from a concealed leak. We can provide supplemental documentation on request.

Customer Reviews

Nicasio, CA Homeowners Who Found Their Leak with Masters Plumbing Service

★★★★★

High-efficiency home with a leak that defied normal detection. Water loss was slow — about 1.5 gallons per hour. The tech used tracer gas after pressure testing confirmed the loss but acoustic detection couldn't localize it clearly. Gas detection found the escape at a micro-fitting under the slab in the utility corridor. Impressive work.

— C. Thornton, Nicasio

★★★★★

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, Nicasio, 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

FAQ — What to Know Before Booking Detection

The most reliable self-check: shut off every fixture and appliance in the house, then watch the water meter for 15 minutes. Any movement — including the small leak indicator dial — means water is escaping the supply side somewhere. If the main meter dial moves with everything off, you have a leak. Call us to locate it.

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.

Yes. Our written detection report includes: technician credentials, equipment identification, pressure test methodology and results, detection method description, leak location with reference measurements, and supporting thermal imagery. This is the documentation format most insurance adjusters require to approve a concealed-leak water damage claim.

We don't rush the detection protocol. The acoustic hold time and thermal scan coverage determine accuracy — cutting them short to save time produces uncertain results that cost more to act on.

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