My zone 2 valve may not be fulling closing, allowing a trickle of water to run. I had a smart-meter alert for a leak after switching on the system a few days ago. Last year I changed out the same head with a check-valve head so (I believe) its not a "gravity" issue given that the head is lower than other parts of that zone.
I switched off water to all the sprinkler system and the leak stopped so I believe that's a reasonable diagnosis of an issue. Here's a photo of one of my valves [img]https://drive.google.com/file/d/1oxxk2Sf9kHrpiyoOSudgunbPhP463y67/view?usp=sharing[/img]

Is it reasonable to think its a diaphragm if I believe the solenoid is properly switching on and off?
Can I replace either or both of the
solenoid / diaphragm without digging
up everything
?
Thanks,
Mark
