Reroute radiant heat tube for construction

Member Posts: 1
Hi all- I have existing radiant floors in the basement of my home. Remodel plans call for cutting the floor to pour new structural footings in a few places. I am wondering if it's feasible to essentially cut the PEX and re-route it around these footings (~3.5' square). Has anyone encountered this before? Many thanks in advance

Well, you have to do what you have to do. Any rerouting is going to involve additional pipe, and therefore at least two splices if not more, and any splice is a potential leak. Therefore, take great care (or have someone else take great care) in making those splices.
There will also be some additional head loss from the splice fittings, which may slightly upset the balance of the loops.
Now. I would very much suggest that you cut and demolish the existing concrete in a small patch at the centre of the new footing, and then use hand techniques to expose the existing tubing to a considerable distance beyond where the rerouting is to begin, taking -- again -- great care not to damage the tubing.Br.

Turn the system on and locate all the loops with an infrared camera. That should limit the damage.
No problem splicing tubes. Use the manufacturer’s recommendation for in slab splices.
Adding 5 or so feet to a loop will hardly be noticeable for flow.Bob "hot rod" Rohr
