How can I locate a small water leak in slab plumbing?

Sounds like a question for the plumbers. Hopefully a moderator can move this over to the plumbing section.

Is the pipe buried in the slab, or under it? Is this a floor heating system?

Call Slab Leak Detection Service. They'll tell you exactly where the leak is. Some experienced plumbers are able to located it using their own, proven methods. But in any case: deal with this ASAP before the leak causes house foundation sinking...
