I bought PVC fitting from Home Depot and notice they are marked with "NFS-dwv". Are this fitting safe to build with? Do they need to say "NFS-PW" or is "NFS-dwv" another way of marking schedule 40 or 80 fittings?

I believe the NSF of PVC is 1 meaning it can stand up to the rated pressure rating so if you pipe is rated at 220 psi it isnt safe past that. Say if the NSF of PVC is 2 that same pipe can with stand twice the amount of its normal work. I pretty sure thats right but if im wrong someone please correct me :-D

...don't use the pipe. Make sure you use materials with the maximum pressure printed on there. Also, I believe PVC deteriorates in sunlight...so cover your cannon, take it inside, do something to prevent UV rays from weakening it. Hrm...I just had an idea... *dumps sunscreen on a piece of pvc to test a theory*
