i got some weird pipe....

[hi]

i was working on my cannon today and looked at the pipe and it clearly said " nsf-pw SCH40 pvc 280psi @ 73 degrees" then, about a foot down the pipe it said "nsf-dwv SCH40 DWV.

can anyone explain this? it is pressure rated, but it said it was both nsf-pw AND DWV. its all one pipe, no adapters or fittings between where it says both nsf-pw and dwv. it looks and feels like normal pvc.

i have shot this cannon many times without any problems, i was just wondering why it said that.

Some pipe just says that; it's fine to use. It's exactly the same, except a different company made it.

[WOW!!]

As long as it says a pressure rating, you are fine.

[hi]

i know its ok, ive taken several hundred shots with it, i was just wondering why thats all.

[WOW!!]

O ok. Well when it says DWV on the side, that means that it is approved by code to be used a a drain,waste and vent system in homes and buildings and things. It doesnt mean that it is cell core, solid wall things like that.
