Properly seating the diaphragm as you described stopped the water leaking from my valve... thank you very much!

What is the small back thumb screw for. I watched the whole video for a description on that. My drip valve won’t stay open more than a minute. I can’t figure out what is going on.

Hello, sorry that info isn't in the video, but it is in another video, Solenoid Valve Features and Options. It's a bleed screw, and it's used to manually open the valve. If your valve wont stay open, it may be an issue of too little flow or too little pressure. Some valves have a lower minimum threshold than others. Or it may just be a defective valve. But first you should check the specs on the valve, then calculate your flow rate and check the pressure.

@@Proirrigationtraining Thanks!! I believe the problem was the Rainbird pressure regulator that was threaded to my valve. After playing with it some more it blew the little white plugs out the side of it failing completely. I replaced it and all is working well now. What scares me is the is the 2nd one of these that have failed, of the only 2 I have purchased and installed 1 year ago.
I’m in a variable speed Submersible well pump which seems to irrigate the yard at around 28psi.
Thanks for the response!!

@@rimrockelectric1926 I've never actually used the Rain Bird version of the pressure regulator. That's a shame about 2 failures, but glad you got it sorted out!
