ok i took my old chamber off because there was a lot of air that was leaking out. I did what you said and put primer on the pipes before i glued them and there isnt one leak on the chamber. Now i think i have a bigger problem. There is air leaking through my sprinkler valve but not much. It makes so...

so just put primer on the inside of the fitting and the outside of the pipe and then put them together?

also i think there is air leaking through the joints of my chamber like where is glued the PVC pipe together. I just used pvc glue but should i have used something more heavy duty?

I think there is a little bit of air that is flwoing through the valve as i fill it. what can i do to fix this?

yea i pretty sure i have the sprinler fowing the right direction and my blowgun is on how you said it should be too. Also when i go to fill the tank up with my air compressor the air is going into the tank but the pressure gauge has no reading. Does this mean i have a leak somewhere?

I am building a spud gun that uses the sprinkler valve witha blow gun. It has an air pressure gauge on the chamber but i cant seem to find a air nossel to put on my chamber so i can put pressurized air into it. Can anyone steer me in the right direction of where i can find what i need.

I bought a Rain Bird 3/4 inch automatic sprinkler valve to modify it for my spud gun. I drilled through the plastic piece and fit my blow gun into it but i wasnt sure if i had to drill through the rubber piece too. Currently i havent drilled through the rubber piece and there seems to be no air flow...
