The method
Every item below is included in the price of slab leak detection in South Gate, CA. Each check narrows the search until the leak can be marked with confidence.
Read the meter with the house silent
Every fixture is shut off and the leak indicator on the meter is watched. If it turns, water is going somewhere it should not.
Gauge test on an outside tap
Split hot from cold
Isolate the failing branch
Where the plumbing allows, each run is capped and tested on its own so the search is limited to the one line that is actually leaking.
Listen through the concrete
Thermal scan on hot lines
Heat escaping from a failed hot pipe shows on a thermal camera as a glow under tile or carpet, backing up what the microphones picked up.
