Pex for Steam Supply and Return
Can Pex be used for steam supply and returns. I am doing a renovation and found some copper supply/return buried behind a wall. The pipes need to be moved a bit. The spot is a little tricky to route threaded iron pipe and the plumber is suggesting an easier solution with pex and some heavy duty fittings. Sounds sketchy to me. I have de-coppered the rest of my system where copper was exposed. Is pex ok for steam and if not, does that mean I am talking to a "knucklehead?. Thanks.
