re: Slab leak detection - plumber recommendation?

Had this happen to me, but don't remember the company i used to detect leak though...they used some type of acoustic technology to find it

apparently older copper pipes in slab are vulnerable to lightning discharge and 2 other folks down my street had same thing happen at about the same time

copper cracked in slab, and the leaking water followed the pipe where it came up out of the slab in the wall and then leaked under my wood floors

they were able to cut and cap the leaking line in the attic and routed a new PEX run
