I have a new industrial building wanting to use PE pipe for their deionized water system. I cant find any standard of manufacture on the piping...Table 605.4 deals with water distribution and there is no PE allowed. In 605.3, for water service, it would have to meet ASTM D2239 or 2737. Is there a code path to allow this? As long as there is backflow between the potable and "process" side, I don't see why not, but I would like a little more of a backup than that...Thanks!
