if you look at ER or even ASM skimmers, they use thinwall gray PVC pipe and it is NOT sch80 wall thickness...probably half the thickness of sch 40 if that. obviously the application would be low pressure, in my case a durso stand pipe.

I remember a LFS had some a while back and it was shipped to them in plastic sleeves. It was thinwall and the outside finish was shiney with no printing. I remember, cosmetic grade PVC plumbing...
