Nice cannon. You manage to find a store with the 1.5" Sprinkler or have to order it? I wish some of the supply stores around me would cary larger than 1".

i quote Da Pneu Kid wrote:
That is a sweet cannon! I love the paintjob too. But... those bell reducers are DWV. since you're only taking it up to 40 psi, it's probly ok, but just don't take it higher than that


what are DWV valves

He didn't say DWV valves, he said DWV bell reducer.

DWV stands for Drain, Waste and Vent.

In short, it is not designed for pressurised use.

Yes they do. They are usually some type of sliding valve like on his. On my neighbors RV their sewage has them. I thought of getting some from a rv supply store and they are made for gravity flow crap and piss(Lol haha) not high pressure air.

You guys keep complaining about the dwv reducers when really the weakest point on the gun is that drainage valve. I wish those came pressure rated-drat :x Ehh cool gun, ive always wanted to use one of those valves

That valve is also after the valve and should receive little force on it.
The air will choose to leave the barrel before it blows that valve.
Come on!
