Pex plumbing and NSF P171
Im looking to put pex into our house for the potable water. We live in Southern California for reference. When looking on the NSF website only a few companies are listed as NSF p171 compliant. It shows Dow Chemical dowlex 2344 and Everhot, yet it seems companies like sharkbite, viega, etc, all list there stuff as being nsf p171. What gives? Are all these companies using Dow chemicals dowlex product and relabeling it?
Here is the link to the p171 pex that pops up:
