safe pipe?

Unread postAuthor: iknowmy3tables » Fri Feb 09, 2007 5:06 pm

Recently I got some 6" pipe for free 8) but of course I had to check to see if it was safe for a pneumatic. I did my research on labels only … I have no idea, because it had every label that I know that could indicate safe or unsafe. Mainly the “NSF-dwv” scares me cause I’ve heard it means its unsafe. Is my find too good to be true?

This is exactly what it said:
6" J-M PIPE PVC1120 SCH40 180PSI @ 73 F ASTMD-1785 NSF-pw ASTMD-2665 NSF-dwv DWV JM90 ME 2004 FEB 22 05 3 (the bar code with number under it) BARCODE NUMBER ___

SCH 40 rated to 180 psi, seems fine as long as you stay under the 180. If it is rated to 180 then of course it is rated for dwv use.

Ignore the DWV label and always look for a pressure rating or nsf-pw

It says its rated to 180psi at 73* F and it also says NSF-PW on it so its fine to use.

Thanks for the help guys, sorry for the late reply, but thanks. I understood that its okay if it says DWV but I didn't know that the same went for the NSF-dwv. well this is really good news :) , now just to get some proper fitting (thats going to cost me)

also to answer VH man's question, I found it... outside... on the ground...

Yeah! We are changing the water mains and meters in our rural Idaho town. We have heaps of large diameter pipe laying all over the ground... now I'll just go collect some when it gets dark...

If you can afford the fittings, go for it. 180 psi is 180 psi
