Stop Guessing Where the Leak Is — Call Masters Plumbing Service in Earlimart, CA
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 Earlimart, CA to locate leaks without speculative demolition.
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
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
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
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
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
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.
From Water Bill Spike to Confirmed Leak Location — 4 Steps
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
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.
2
Zone Isolation & Pressure Decay
We isolate the supply system into zones — hot side, cold side, and if possible, individual branches — and pressure-test each zone to determine which branch is losing water. This narrows the area of active search significantly before detection equipment is deployed.
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 Earlimart
★★★★★
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, Earlimart
★★★★★
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, Earlimart, CA
★★★★★
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 from Earlimart, CA Property Owners
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 pressurized supply lines in concrete or metal pipe, acoustic detection is typically accurate to within 6–18 inches under ideal conditions — quiet environment, no interference from other water use, metal pipe conducting sound clearly. Thermal imaging is accurate to the size of the wet zone it reveals, which varies based on how long the leak has been running and how far moisture has migrated.
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.
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.
