Why Slab Leaks Happen in North Texas
Shifting clay soil, aging copper lines, high water pressure and poor installation can all wear a line under the slab. Because the pipe is hidden, the leak often runs for a long time before it shows.
How the Leak Is Located
- Confirm the leak by shutting off all fixtures and checking the meter.
- Use acoustic listening equipment to find the sound.
- Use electronic or thermal detection to narrow the spot.
- Mark the location before any opening is made.
