Hi, I'm new here and losing whats left of my mind! Had a slab leak and must repipe asap - have gotten conflicting advice on whether to go with Flowguard Gold PVC (glued joints) or Pureflow ViegaPEX tubing with "crimped" fittings. Also, any feelings regarding the Manabloc system with the box that allows you to turn on/off individual sections of the house? One guy says is good, another says won't hold up good and expensive to fix. The PVC guy says he can run down the attic through an outside wall to get to our kitchen sink. The Pureflow guy says no, outside wall won't work, will go through the dining room inside wall and then run pipes INSIDE the cabinets all around the wall to get to the sink. Any and all advice SO VERY MUCH APPRECIATED! THANKS!
