I have used a 1 inch sprinkler to pilot a 1.5 inch sprinkler valve.
I had to because the blow gun was to restrictive on the larger valve.

The blow gun was the hint the equalization leakage is high. Too high.
Tech this is why I am confused.
I made the statement of a restrictive blow gun on my cannon.
It has nothing to do with resrictive blowgun on his! He never even stated that.
I thought you were stating that I also had a bad or messed up main valve
because of your reference to "blow gun was the hint"
I could have used a ball valve but they are inconvenient and ugly for the purpose I wanted. That is to have a trigger handle.
I was referencing the very original post. No blow gun was mentioned but it is in the photo of the cannon in the original link in the very original post.
To make matters worse, there is an elbow in both the pilot for the sprinkler valve and an elbow on the discharge of the sprinkler valve. I made a guess to the addition of the latter made a change in operation. I may be completely off base on this one. Too many variables and much confusion on which elbow. In providing the back pressure to the sprinkler valve, I was referencing the PVC one on the left.
