This action is based upon recent statements made during the Uniform Plumbing Code hearings on the public comments on the 2015 code cycle change submissions. It was perceived by some that installers should rely on this document for the most accurate installation requirements for PEX tubing, mainly horizontal hanger spacing. Manufacturers and installers are in agreement that the installation instructions provided by the manufacturer and the plumbing code as adopted. In the case there is a conflict of those two documents, it is required by code that the most stringent takes precedence. This ballot adds the industry consensus for larger diameter PEX horizontal hanger spacing and refers the user to manufacturers installation instructions.
