The method
Booking slab leak detection in Lemon Grove, CA gets you these checks, in this order, with notes you keep at the end.
Read the meter with the house silent
Gauge test on an outside tap
With the main closed for fifteen minutes, a gauge threaded onto an outdoor tap shows whether pressure falls. A drop means water is escaping even if the meter hardly registers it.
Split hot from cold
Isolate the failing branch
Listen through the concrete
Ground microphones pick up the sound of water escaping under pressure, and the sound peaks close to the failure.
Thermal scan on hot lines
Mark it and explain the options
Tape goes down over the failure, the readings are noted for you, and you hear which repairs would work in your house and why, with no quote attached yet.
