The method
Every visit for slab leak detection in Lynwood, CA follows the same order, so the result is a location you can act on rather than a best guess.
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
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
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.
