Ok, thanks for everyones help!

Not true in the least. I've seen 8" DWV fittings that are over 1/2" thick. The main reason we don't use DWV is because it isn't made the same way, and the socket depths are much shorter than potable water fittings.[/quote]

So is it still ok to use a DWV bushing as long as both pipes are rated ...

Really? That's great... yeah, both pipes are pressure rated to well over 250 psi. I guess I'll just go downtown and buy the parts tomorrow! Thanks a lot!

This is what I need:

Is what I want a socket weld x pipe? (One end needs to have the 1" pipe slip into it, the other needs the 3" pipe to slid over it)

ok thank you.

The projectiles I am going to use are: C batteries in the 1" chamber, soda bottles in the 3", and potatoes in the 2" barrel. I don't know how tight a fit the c batteries and the soda bottles are.

Does the (red) fitting need to be pressure rated? It comes after the sprinkler valve and isn't connected to the air chamber. However, I'm assuming that it will still have to withstand quite a lot of pressure when all the air escapes. (It is a 1" valve connected to either a 3, 2, or 1" barrel.) The ...

Well, they are both 1" orbit valves... i realized after i modded them that i should have gotten bigger valves, but I cant send them back now. good to know for next time though. Thanks for the offer if I need help ill email you.

I have a pretty large one, apparently it is quite hard to find. It is rated to like 160 psi and someone told me that even when it isn't modified, (which I can't because it is held together with welding), it had a larger air flow than most. (I think your talking about the wired L looking thing on my ...

Ok, thank you very much.

Is it alright to use a sprinkler valve on its side? does it lose any power or anything? I wanted to put 2 on their sides so that I can easily connect them with a t joint hose barb and some hose. Thanks.

Thank you very much.

I looked everywhere and couldn't find a description descriptive enough so that I could be sure I had what I was looking for. (I looked on the website too). I am looking for the name of 4 different kinds of fittings. I was interested in attaching multiple barrels to 1 output, so I needed either: a ...

Thanks very much.
