Leak Detection Services in Whittier, CA

How We Find Leaks Without Opening Walls

Detection is a process of elimination run with several instruments, because no single tool is right for every leak.

A meter test comes first and is free information: shut every fixture, watch the meter. Movement means active loss somewhere on the system. Pressure isolation then separates hot from cold and the house from the yard line, which narrows the search to a section of the system before we look for a point.

Acoustic listening equipment amplifies the sound a pressurized leak makes escaping a pipe — under a slab this is often the tool that finds the exact spot. Thermal imaging reads temperature differences through finish materials, which is why hot-water slab leaks show up so clearly. Tracer gas is the fallback for leaks that are too small or too quiet to hear, introduced into the isolated line and detected where it surfaces.

Run in that order, most leaks are located to within a few inches without opening anything.

Whittier's Two Dominant Leak Patterns

This service area produces a lot of two specific failures, and both are age-related rather than accidental.

Pinhole leaks in copper. Homes repiped or built in the copper era develop pitting corrosion from the inside out. Los Angeles County's water is hard, and the combination of mineral content, water chemistry and decades of service produces the classic pinhole — a tiny hole in an otherwise healthy-looking pipe. The first one is a repair. The third one in two years is a repipe conversation, because pinholes rarely happen alone.

Galvanized steel failure. Earlier builds across Michigan Park, Orange Drive and older pockets of West Whittier still have original galvanized supply. Galvanized corrodes and scales internally, restricting flow, then fails at threaded joints where the wall is thinnest. Gradually falling pressure across the whole house is the tell.

Under a slab, either failure produces the same symptom set — warm floor, high bill, sound of water — and the same urgency, because the water is going somewhere and that somewhere is the soil under your foundation.

What Happens After We Find It

We locate and document; the repair itself is licensed plumbing work, and we coordinate it rather than pretending otherwise.

For most slab leaks there are three repair paths: spot repair through the slab at the located point, rerouting the affected line overhead or through walls to bypass the slab entirely, or a full repipe when the pipe material has reached end of life across the house. Each has a different cost and a different disruption profile, and the right answer depends on the pipe material, the number of previous failures, and how long you plan to own the home.

What we do handle directly is everything the water did on its way out: drying the slab and the affected assemblies, removing what cannot be dried, and restoring the flooring and finishes that had to be opened — see slab leak water damage restoration.
