i just got a 1" sprinkler valve but it leaks. probably because there is too much pressure. i think i will leave my ball valve on this one and save the sprinkler valve for a different cannon

thanks for the help :D

Well acording to a calculator (I dont remember which one but it tells you how much pressure a 12 gram would put in) it only puts 125psi if I remember right. This is one of my old cannons and I dont use it very much. I put a compresser fill nipple on it because 12 grams were getting expensive anyway.

Spudstuff, your post i irrelevant. The original poster is her so its no a big deal.
If you have a problem go pm a mod.Ot just kill yourself and do us all a favor.

But ya, my valve is rated to 150:D
The ball valve should do fine, as long as it idnt hard to open.

Frankrede you need to get to know spellcheck. I had to read your post 3 times in order to understand it.

The ball valve on is fine because I barely use it anyways so its more of when my friends come over I show it to them and shoot some water. :) Makes a loud poping noise. :P

You're able to delete the last post you've made. But now that you've double-posted, that can't be done.
