Leak Detection (Slab Leaks)

Precision Leak Detection: Finding the Invisible Problem

Protect Your Foundation from Hidden Water Damage

A high water bill, a warm spot on the floor, or the sound of running water when everything is off—these are signs of a hidden leak. In San Antonio, “Slab Leaks” (leaks under your foundation) are a serious threat to your home’s structural integrity.

Merritt Plumbing uses advanced acoustic listening technology and thermal imaging to pinpoint leaks without destroying your home. We find the leak before we dig.

Our Process:

  1. Isolation: We perform a hydrostatic pressure test to confirm if a leak exists and isolate it to the hot or cold line.
  2. Location: We use electronic listening devices to “hear” the leak through the concrete slab, marking the exact spot.
  3. Options: We present you with multiple repair paths:
  • Spot Repair: Jackhammering a small access point to fix the specific break.
  • Reroute: Abandoning the line under the slab and running a new, accessible PEX line through the attic or walls (often the safer, longer-lasting choice).

Don’t Wait. Water under your foundation causes heaving, cracking, and mold. If you suspect a leak, call the experts immediately.

The Merritt Difference: We are also concrete experts. If we have to break your slab, we pour it back to professional standards—one call, complete restoration.
