well my dual chamber sprinker cannon doesnt really shoot. it kinda just lets air out when you depressureize the sprinkler valves. you can watch the pressure gauge and see it drop pressure. it lets of a bit of a burst but nothin to justify 40 dollars per vavle to fire it with. my cannon has 2 3 inch by 3.5 foot chambers into a 1.5 inch barrel ...6 foot i beleive. each chamber has a 1 inch sprinker valve...not sure of the model but it is moded to fire better. any ideas is this just due to a bad valve choice?(i am pretty limited by my choices in westcliffe) thanks any ideas would be great i would really like to get it good with the money that was put into it.

i don't know if you did this yat..but the cross shaped knods that are in-line with your air resivours are a shut-off valves. they may not be open all the way...so try adjusting the knobs. that 3'' dwv elbow that's hooked up to your barrel might slow down the rushing air i don't know if you want to change your design. i have never seen a gun like yours before!!!! really interesting nice work!!!!
