Bud16415, it was suppose to be a permanent fix that included everything. The supervisor said he could not find the leak after making multiple small digs. At the end, the supervisor pointed it out and he dug there and found the leak. He put on the rubber and a hose clamp, buried it back up, re-poured 1/2 inch of the concrete for a 6 inch slab, and re-tiled with the extra tile we had. He did not attempt to replace the leaky pipe which was a permanent repair. He patched everything back up as if it was so we would never know.
The reason I knew it was there because the floor was unusually warm and our gas bill doubled. Plus, we had the same problem with the same pipe with the same exact symptoms 13 years ago.
Unfortunately, there is no shut off valve for that one line. I was thinking of installing one just to troubleshoot.
CallMeVilla, I am more in favor of the re-route pipes like in your last picture with call-outs. In fact, I considered it before I posted on here but was hoping that there was a better solution. I will have to do some further digging this weekend like NealTw suggested to see how the pipe is connected and if this was a possible solution.
I really thank everybody for the great information and trying to help. I will keep everybody posted.
