    We're getting ready to install a Pex homerun system with a Manabloc. Viega Pex has a bend radius of 8 times the pipe diameter or 4" for 1/2" pipe. We bought the 100' roll of Pex so the pipe has a curved "set" in it. We're finding that whether you straighten or bend the tube, it wants to return to its original curve. Can Pex be heated with a heat gun? If so, after it cools will it this take a set at the new angle? I've seen both plastic and metal bend supports, but these are not useful since we are also planning to insulate the Pex to control condensation and conserve heat. I would appreciate any tips anyone has on bending the tubes.
