Forgive me if this has already been asked and answered; I couldn’t find much in the way of an answer in the files: It happens we’re having a discussion about Manblock, Wirsbro, and the like. Also, about PEX as a good substitute for copper. Is Wirsbo a superior system? There’s a lot of comment and confusion, but not many solid answers, so I guess we’d like to hear as many opinions and comments from experiences as possible. The use will be a residence built on a slab. :confused
