I wouldn't go over 80 psi with that, with all the DWV that's there. And where have I seen that red and black paint before? It's not painted the same way though. Oh well, I still had to say that.
And this is semi/full auto how? What kind of loading system is there?

Sorry to say it, but aren't some/most of those fittings DWV?

And it looks to me as if the sprinkler valve is on the wrong way round, but I don't know which way it's meant to fit on to your launcher. I'm probably wrong about this bit anyway.

It's very nice, I'm just confused.

Beat you to it.

Ah. Damn - second page that I didn't see.

Whatever. At least I can recognise the DWV stuff now (not that it ever matters to me.)

uhh it's kinda funny asking whats on my own gun. What's DWV?

It's the "crazy" PVC. The Ys and weird sized joints with really short socket depths.

The cannon looks cool but next time look for pressure rated stuff because the real fun starts when you take it over 100 psi

yea i was wondering that for a while too thx for the info

Usually Sch 80 fittings look like the DWV except your wallet knows when you but SCH 80.

I've taken another one that I made over 120psi and I cracked a rubbermade trashcan with a paintball. Im not able to take it over like 140 because of the valve. It can only handle 150psi of H20 blast pressure. Air would go faster so I would use like 135psi otherwise it could break the valve. I m not worried about the fittings, the smaller ones have higher psi ratings, like 600psi.

Wait, what are the pressure ratings for DWV?

If i were you, i would not use the co2 for the gun, but you can find a person that will fill up your co2 tank with air, that way it is not cold, but it is still in the same size container.

DWV pipe and fittings are never rated, unless stamped as such.

Some pipe is odd in that it is listed as DWV, but has a rating of about 260 psi or so.

However, your fittings wouldn't have been rated. It might have taken about 100 psi without too much risk.

However, I am not in any way promoting you doing that. If you do that and end up with PVC nose and tongue piercings, I will not be held responsible. I am suggesting that it might be possible if done and checked carefully.

The cold from CO2 isn't really a problem if it has been injected fairly slowly - that causes less temperature drop.

CO2 is perfectly safe to use if correctly done. The biggest risk is accidentally missetting your regulator and your joints failing with excess pressure.

joannaardway, so with a remote coil and a high pressure ball valve it would be completely safe?

This is the idea that I was going to use. It goes: CO2 tank --->remote coil--->ball valve--->PVC tank. Im not sure if Id put another ball valve in just for safty or not though.

Put another one in. Open the first one like on a propane meter, close it, open the one closer to the tank, close it, and keep adding smaller amounts that way. It won't be as cold and you'll be safe.

0 PSI. It is for Drain, Waste, and vent.
