I am about to install a Manabloc system with Vanguard/Vanex PEX tubing in my new house. I just stumbled across your site & I love it. I was wondering if anyone had used Vanex before. I am still nervous using a product I'm not familar with. Not about the installation, but about safety, leaching from lines into drinking water, etc. I'm a mom so this is the way my mind works! I am a stay at home mom who grew up the daughter of a builder. My dad (who passed away last month) taught me how to do just about everything when it comes to building a house. I am very proud to be finishing the house we started together using everything he taught me. I think he would approve of pex. He worried about me sweating copper.
Thanks for your help!
