A slab leak is a leak in a water line under the concrete floor. Copper under a slab can pinhole over time, and if the ground swells and shrinks with the weather, that keeps working on it. That can happen in Sky Ranch, Carlton Hills or any other Santee neighborhood where a home sits on a slab.
The contractor chooses the approach job by job. Detection equipment can locate it through the concrete, often to a small area, which can help keep the repair limited. From there you have options. The contractor can open the slab at that one spot and fix it, or skip the slab altogether and reroute a new line through the walls or attic.
Which way to go depends on the pipe. A first leak in an otherwise healthy line can point to a spot repair. If it's the second or third leak, a reroute or repipe can be the better choice. You'll hear the tradeoffs in plain English, and the decision is yours. A licensed contractor does the work when you say go.
