And we understand the hazards of PVC. But we glued everything and made sure that there are no leaks. The PVC is very heavy and was brand new when we glued it. So as of right now there is NO chance of it breaking. These cannons have been through a lot, and I know that a lot of PVC cannons have bursted... but because this is brand new PVC there shouldn't be any chances of it shattering... just an end cap or reducer popping off. But we made sure that the glue was perfect and its definitely covered. Thank you for your concern. As of right now we're looking for nice metal tubes in our closet for our 3rd Gen tanks.

I wasn't going to post in this thread (I've posted enough about the dangers of PVC) but this post has enough poor information that I needed to post.
New vs. old PVC -- Makes very little difference. PVC can fail on the 1st or on the 1000th shot, with no (or very little) warning.
Glueing PVC makes it stronger -- Depending on the type of glue (or cement) this will (more than likely) weaken the PVC as it breaks up the polymer chains within the PVC. Typically bonding plastics to plastics weakens the strength due to the bonding process at the molecular level.
"there is NO chance of it breaking" -- Never assume nothing can go wrong or something cannot break. Things can always break with enough force applied in the wrong (or right) directions. Instead plan on worst case and make it safe. Especially if it will be near the public.
I am very happy to hear that you are looking into metal tubes for your next generation t-shirt launcher.
Sorry to be so negative ... but pressurized PVC and the public always brings out the 'safety police' in me.
