One of my customers was setting a toilet flange at his house and drilled a hole through the radiant tubing. I'm having him open up the floor for the repair, but I don't know what kind of PEX it is. If it's PEX A, I can use my expander tool for Uponor-type fittings. From the pictures, even though the manifold is Uponor, the tubing isn't necessarily Uponor. (I don't think the damaged tubing is on the red loop.)
No matter what kind of tubing it is, I guess my main question is how to splice a new piece of tubing between two ends that are set in concrete. Is there such a things as a Uponor repair coupling?
