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.

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.
