Hi Bernard - thanks for the review. We appreciate that you sent over pictures - we figured out that the incorrect diaphragm was sent and we have the correct ones on the way! Our apologies for the confusion!
“Have very little experience with the irrigation box and valves for my drip system installed about 16 years ago. Did some troubleshooting with the controller and narrowed it down to a bad Diaphragm. Contacted the sprinkler supply store through email with about 4 or 5 pictures of my valve and right away they identified what I had. Weathermatic Black Bullet Valve which they don't make any longer. Sprinkler Supply Store sent me the link to the correct valve and received it quickly and installed it. Problem solved!”
