All Pvc pipe is DWV, but its the fittings you have to look for nsf-pw, not a dwv on fittings.

Pvc pipe should have both the NSF-DWV and a NSF-PW

ive taken 40mm dwv to 110psi. alot of it depends on the size of the pipe. nice cannon by the way does the double chamber increase the performance much ?

Yes, but if the pvc has a weakeness or fault youre screwed
I dont think its worth it, for any size cannon.
The "double chamber" works the exact same as the same length of pipe inline.
really good quote/phrase here

Things thing looks awesome, just replace the dwv fitting with a pressure rated T fitting. Also, nice first cannon.

No but it helps when you shoot things that are really tight in the barrel it used to have foam there where the chamber splits.
