Slab Leak Detection & Repair in Temecula & Winchester, CA
A slab leak is a water line leaking underneath your concrete foundation. Because the pipe is buried, the first clues are indirect: a warm spot on the floor, a water bill that jumps for no reason, or the sound of running water when every fixture is off. 3 Kings Plumbing locates slab leaks in homes across Temecula, Winchester, French Valley, Menifee, and Murrieta, then explains the repair options plainly before anything gets cut.

Listening equipment and pressure testing narrow the leak to the smallest possible area.
You choose between a targeted spot repair and a re-route after we explain both honestly.
Slab Leak Detection in Temecula, Winchester & Western Riverside County
Most homes in this part of Riverside County sit on slab foundations, so pressurized copper or PEX lines run under the concrete. Over time, soil movement, abrasion where a pipe crosses rebar, water chemistry, or a pinhole in aging copper can start a leak. Left alone, that water saturates the sub-slab soil, damages flooring, drives humidity and mold, and can add hundreds of dollars a month to your water bill.
Detection is the part that matters most. We isolate the system, check pressure behavior, use listening equipment and thermal clues, and narrow the leak to as small an area as possible. Guessing is expensive: opening the wrong part of a slab costs money and repairs nothing. Careful location keeps the fix small and predictable.
Once the leak is found there are usually two honest paths. A spot repair opens a small section of concrete and replaces the failed length of pipe, which makes sense when the plumbing is otherwise in good shape and the leak is accessible. A re-route abandons the line under the slab and runs a new one through walls or the attic, which is often less invasive and a better long-term answer when the pipe is old, has leaked before, or sits under finished flooring you do not want to lose.
We walk you through both, including what each involves for your flooring and drywall, so you can decide with real information. If a whole-house re-pipe is the smarter investment because the same line keeps failing, we will say that too. Call or text 3 Kings Plumbing if you suspect a slab leak anywhere in Western Riverside County.

We isolate the plumbing, pressure test, and use listening equipment to pinpoint the leak before opening anything, which keeps the repair area as small as possible.
It depends on the pipe age, location, and history. A spot repair suits a one-off failure in sound plumbing; a re-route is often better for older lines or leaks under finished flooring.
Yes. We handle slab leak detection and repair throughout Temecula, Winchester, French Valley, Menifee, Murrieta, Lake Elsinore, and Wildomar.
