Leak detection in Dallas, TX
Turn off every fixture and watch the water meter's leak indicator. If it moves, water is leaking somewhere. A plumber uses pressure tests, acoustic listening and thermal imaging to find the leak so only a small section of wall or floor has to be opened.

Leak detection for Dallas homes
Hidden leaks waste water and rot framing before anyone sees them. In dry climates a slow leak can evaporate as fast as it drips, so a stain may never appear. The first sign is often a water bill that jumps between seasons that should match.
For the full guide, including what you can safely do before a plumber arrives, see leak detection explained.

Leak detection in Dallas: what's different
Dallas sits on some of the most expansive clay in Texas, and slab leaks are routine. They often appear after a dry summer followed by heavy rain, when the soil moves.
A plumber confirms the leak at the meter, then uses acoustic listening and thermal imaging to locate it. Permits for repairs come from the City of Dallas Development Services department.
Older Dallas homes in Lakewood and Oak Cliff have aging copper and galvanized lines that leak more often.

Other Dallas conditions that affect plumbing
- Clay soil and cast-iron drains: Soil movement and aging cast iron under slabs lead to cracked drains, which a camera inspection and hydrostatic test can confirm.
- Winter ice storms: North Texas gets occasional ice storms and hard freezes, and attic or exterior-wall pipes in heat-built homes are the first to burst.
- Hard water: Mineral-heavy water shortens water heater life and clogs aerators and tankless heat exchangers.
- Winter Storm Uri lessons: The February 2021 winter storm burst pipes across Dallas because many homes have plumbing in attics and exterior walls. Insulating attic lines, sealing gaps and knowing where the main shutoff is are now common requests before winter.
