Copper buried in a slab can develop pinholes over the years, and where the ground moves, that can add to the wear. It happens in slab homes anywhere in Poway, from Old Poway to Rancho Arbolitos, and the longer it runs, the more water ends up under the floor.
The contractor works out the approach on each job. Detection equipment can hear the leak under the concrete and narrow it down. There are two main options. One is a repair at the leak through an opening in the slab. The other leaves the slab alone and runs new pipe overhead.
The right choice depends on the line. One leak in pipe that's otherwise sound can mean a spot repair. Repeat leaks can be a reason to reroute or repipe, based on what the line shows. You get the options and tradeoffs in plain English, then you decide, and a licensed contractor does the work when you say go.
