Just bought a cabin in the woods but the plumbing is screwed p. Former owner said he used pex when he built it but admitted he didn't know what he was doing. He buried the pex under the slab and actually made the couplings and other connections under the slab that was poured over it. Now I need to fix this mess. is there a way to get new pex under the slab and then connect it above grade to a manifold. Several of the connections seem to be leaking under the floors and the cabin in weeping from under the slab in several places. I know electricians can fish wires by using a fish tape is there anything like this for pex?
Thanks for your advice - would rather not break open the floors.

When wires are fished, they're fed through hollow spaces, from opening "A" to opening "B". You probably don't have the hollow voids under the slab. Can you reroute the piping in the attic? Holes could be bored under the slab, to openings that you have to cut in the concrete.

Thanks for the feedback, I have cut an 18" square hole in the floor through the concrete and found multiple pex lines, connections, and leaks. I was able to get to a couple and replace the old connectors and re-crimp the [ex fittings. It works for that area but I can feel other connections under the concrete that are a foot or so away, my fear is that if I continue to cut the concrete I wont find an end to the problems. Your idea of re-routing through the Attic may work. The cabin has a 3/12 roof pitch so its tight near the walls, but the incoming water line comes up near the center of the cabin. I may be able to install a manifold and take everything up to the attic.
Is there anything you know of that I can use to prevent the problem from occurring again where I was able to fix the damaged .
Again Thanks

Electricians use a fish tape INSIDE pipes that are already installed. They do not "pull pipes" with a fish tape.

1. There should NOT have been ANY connections under the slab. Doing so violates almost every code in existence.
2. Making proper joints is the only way to minimize the possibility of it happening again.
