Slab Leak Detected and Rerouted in San Antonio, TX

A water leak you can't see is often worse than one you can. When water is escaping beneath your home's concrete slab foundation, it can go undetected for weeks — quietly damaging your foundation, spiking your water bill, and creating conditions for mold. That's exactly the situation a San Antonio, TX homeowner faced, and Rapid Plumbing was called in to find it and fix it.

Finding the Leak First

Before any repair can happen, the leak has to be located — and that requires more than guesswork. Our team used electronic leak detection equipment, including acoustic listening devices and pressure testing, to pinpoint the exact source of the leak beneath the slab. This non-invasive diagnostic process lets us identify the problem without unnecessary digging or demolition.

Once the compromised section of water line was confirmed, we documented the findings and presented the homeowner with a clear plan of action.

Why a Reroute Makes Sense

When a water line fails under a slab, there are two options: dig down to repair it, or abandon the damaged section and reroute the line through a new path. In most cases, rerouting through the attic space is the smarter, longer-lasting solution — and that's what we recommended here.

By installing a new overhead water line through the attic, we were able to restore full water service to the affected fixtures without breaking concrete or disturbing the foundation. The new line is accessible, inspectable, and built to last. It's a cleaner repair that protects the integrity of the home.

What the Job Included

Our scope of work covered the full process from detection to restoration:

Leak detection and system diagnostics, identification and documentation of the leaking line, isolation and abandonment of the damaged underground section, installation of a new water supply line routed through the attic, connection to the existing plumbing system and affected fixtures, pressure testing to verify integrity, and full restoration of water service.

Don't Ignore the Signs of a Slab Leak

If you're noticing a sudden increase in your water bill, warm spots on your floor, the sound of running water when nothing is on, or unexplained wet areas near your foundation — don't wait. Slab leaks get more expensive the longer they go unaddressed.
