Right... well... umm... I have no idea. I've tried this with smaller diameter pipe and it didn't work... but mine was fail, sooo.... i'd say just go for it and figure it out
I saw some PVC a few days ago that had the pressure rating nsf-61. I've never heard of this before, and was wondering what exactly is the difference between this pipe and nsf-pw. It said that it was rated to 600 psi.
