I have a laundry room built on a concrete slab with radiant heat. The room has a utility sink. The previous owner ran a pvc pipe for the drain across the floor to the center of the room (about 4 feet) to an existing floor drain. This is a tripping hazard and is unsightly. Can I cut into the concrete and bury the drain pipe? How do I deal with the radiant heat? Do I just try my luck and hope I don't cut any heating tubes? Can I repair them if I do? Thanks in advance for the help.
