Professional Leak Detection in Granger, TX — Acoustic, Thermal & Pressure Methods
A water bill that jumped 30% with no change in usage. A ceiling stain that keeps reappearing after patches. A soft spot in the flooring with no visible source. These are signs of a hidden leak that's been running long enough to cause structural damage — and every day it runs is money lost and damage accumulating. Masters Plumbing Service uses acoustic ground microphones, thermal imaging cameras, and precision pressure testing in Granger, TX to locate leaks without speculative demolition.
The Tools Behind Accurate Leak Detection in Granger, TX
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
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
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 Granger, TX.
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
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
We format detection reports specifically for insurance submission and can provide documentation on our detection equipment and methodology to claims adjusters on request.
Finding a hidden leak isn't a single step — it's a protocol that combines water loss confirmation, zone isolation, and targeted detection in sequence.
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
We document findings with thermal images and note detection readings at multiple grid points to triangulate the strongest signal.
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
What Customers Say About Our Detection 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, Granger
★★★★★
Ceiling stain in the living room kept coming back despite two drywall patches. Masters Plumbing Service ran the thermal camera and found the wet zone was traveling from a supply line joint 9 feet away and flowing down a horizontal framing member — explaining why the patch kept failing. They marked the actual pipe location, we opened 8 inches of wall there, and the repair held. No more stain.
— B. Osei, Granger, TX
★★★★★
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
Leak Detection Questions We Answer in Granger
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.
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.
Yes — and for most residential leaks, we can repair the failure the same day detection confirms the location. Our service trucks carry the repair materials for the most common supply line failures. We quote the repair as a flat-rate job separate from the detection fee, and you decide whether to proceed with us or take the detection report to your own plumber.
