How a Plumber Detects Underground Water Leaks?

Finding underground water leaks requires a methodical approach that narrows the source before digging. In Los Angeles and Orange County, pros combine listening equipment, isolation tests, and line mapping to protect landscaping and concrete.
How Pros Detect Underground Water Leaks
Pressure and Isolation Checks
Technicians close valves to segment lines and watch gauges for loss. By isolating branches, they pinpoint whether the leak sits under a slab, in the yard, or at a service line.
Acoustic and Tracer Methods
Listening devices “hear” turbulence from underground water leaks. In some cases, trace gas or dye helps confirm the path before targeted access.
What to Do Before and After a Locate
- Document wet spots, meter movement, or sudden bill increases.
- Clear access to hose bibs, shutoffs, and the water heater.
- After repairs, retest pressure and monitor for drying over several days.
Limiting Surface Damage
Camera inspections and utility locates reduce unnecessary demolition. Focused cuts or small digs protect hardscape and keep restoration scope manageable when fixing underground water leaks.
