Stop Guessing Where the Leak Is — Call Masters Plumbing Service in Griffith, IN
The difference between a $300 pipe repair and a $3,000 drywall-and-remediation project is often just whether the leak was found before or after excessive wall opening. Our Leak Detection service in Griffith uses the same detection methods utilities and insurance adjusters rely on — to pinpoint the failure location before anything is cut.
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
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
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
For leaks that don't produce sufficient acoustic signature — very slow leaks, polyethylene pipe, or leaks deep under concrete — we can 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. The detection sensitivity can locate leaks that produce no discernible pressure drop during a standard timed test.
What We Locate
Hidden Leak Types We Find and Document
Hidden leaks occur in different locations throughout a property — each requiring a slightly different detection approach. Here's how we handle the most common scenarios in Griffith, IN.
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
We document the thermal anomaly, mark the approximate pipe location, and recommend a minimal access cut rather than a wide wall opening.
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
We format detection reports specifically for insurance submission and can provide documentation on our detection equipment and methodology to claims adjusters on request.
Our Systematic Leak Detection Approach in Griffith
Here's exactly how a Masters Plumbing Service leak detection call plays out.
1
Initial Water Loss Confirmation
This step confirms we're looking for a real leak rather than meter error or a normal appliance cycling.
2
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."
3
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.
4
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
Real Leak Detection Reviews from Griffith
★★★★★
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, Griffith
★★★★★
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, Griffith, IN
★★★★★
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.

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.
In most cases, yes — the detection phase is entirely non-invasive. We locate the leak using acoustic, thermal, and pressure methods without any demolition. The detection tells us exactly where to open, which means the access opening is minimal rather than speculative.
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.
