There are huge safety concerns with PVC, because PVC IS NOT DESIGNED TO HOLD ANY KIND OF COMPRESSED GAS, AND HAS BEEN BANNED BY OSHA FOR USE WITH PRESSURIZED GAS IN INDUSTRY.
PVC is rated to 350 psi of air by UL;
I got this from a team mentor who builds PVC potato cannons, and has never had one explode at pressures as high as 150 psi (fired like a bazooka)
