The method
The sequence below is how slab leak detection in Hesperia, CA avoids the classic mistake of cutting the slab in the wrong place.
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
Closing the valve on the water heater shows whether the loss is on the hot side. That single step decides which tools come out next.
Isolate the failing branch
Listen through the concrete
