Leak Detection in San Diego, CA β€” No Guesswork, No Unnecessary Demo

The difference between a $300 pipe repair and a $3,000 drywall-and-remediation job is often just whether the leak was found before or after excessive wall opening. Our detection service in San Diego uses the same methods utilities and insurance adjusters rely on β€” to pinpoint the failure before anything is cut.

Why Detection First

How Masters Plumbing Service Finds Hidden Leaks Without Guessing

No single detection method works for every leak scenario. Our techs are trained on four distinct approaches and select the right tool β€” or combination β€” based on pipe type, building construction, and leak characteristics.

πŸŽ™οΈ

Acoustic Ground Microphone

Pressurized supply line leaks create a low-frequency sound as water escapes the pipe and contacts surrounding soil or structure. Our amplified listening devices filter background noise so we can triangulate the loudest point β€” often to within 6–12 inches of the actual break, through concrete slabs or behind drywall.

🌑️

Thermal Infrared Camera

Particularly effective inside insulated wall cavities and for finding the extent of moisture spread beyond the immediate leak point β€” telling us not just where the pipe is failing but how far the moisture has already traveled.

πŸ“‰

Pressure Decay Testing

Pressure decay testing is the standard by which we confirm a leak is present before committing detection equipment time. A rapid drop vs. a slow one also indicates the approximate size of the escape point.

πŸ’¨

Tracer Gas Detection

Tracer gas is the method of last resort for the most challenging cases. It adds setup time but finds leaks that acoustic and thermal methods alone can't conclusively locate.

What We Locate

Leak Detection for Walls, Slabs, Pools & Irrigation

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

Under Slab

Slab Leak Detection in San Diego, CA

Thermal imaging supplements acoustic detection for slab leaks, identifying the thermal anomaly that appears on the floor surface as water migrates through the concrete.

Professional Leak Detection technician working in San Diego, CA
In-Wall

Hidden Pipe Failure Behind Finished Surfaces

We document the thermal anomaly, mark the approximate pipe location, and recommend a minimal access cut rather than a wide wall opening β€” typically saving hundreds in drywall repair costs.

Water Main

Underground Supply Line Detection

Supply lines between the meter and the structure run underground and are vulnerable to corrosion, ground movement, and root damage. A main supply line leak shows as 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 β€” we mark the surface above the leak so the repair crew opens only the section they need to.

Pool & Irrigation

Pressure Testing for Pool Plumbing

Irrigation system leaks in main supply 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.

Our Process

How Our Leak Detection Process Works in San Diego, CA

Here's exactly how a Masters Plumbing Service leak detection call plays out in San Diego, CA.

1

Initial Water Loss Confirmation

This step confirms we're looking for a real leak rather than a meter error or normal appliance cycling.

2

Zone Isolation & Pressure Decay

We isolate the supply system into zones β€” hot side, cold side, individual branches β€” and pressure-test each to determine which is losing water. This narrows the area of active search before detection equipment is deployed.

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 relative to fixed reference points, and thermal imagery. If you want us to repair the leak, we quote immediately and can execute same-visit.

What Customers Say About Our Detection Service

β˜…β˜…β˜…β˜…β˜…

High-efficiency home with a slow leak β€” 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 for a very difficult leak to find.

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.

Pool was losing 2 inches per day β€” more than evaporation. 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.

FAQ

Common Questions About Our Leak Detection Service in San Diego

If the meter test confirms water loss, call us before opening any walls. Our detection equipment locates the failure to within inches in most cases β€” which means a small, targeted access rather than speculative wall demolition.
In most cases, yes β€” 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 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 β€” quiet environment, no interference from other water use, metal pipe conducting sound efficiently. Thermal imaging is accurate to the size of the wet zone it reveals, which varies based on how long the leak has been running.
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 β€” cutting them short 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 plus repair before anything is cut.
