I noticed the other day that one of my sprinkler valves appears to be leaking. The valve still works, but when testing it I noticed the solenoid is also buzzing. I'm not sure if these two things are related?
I tried testing the solenoid manually using 9v batteries and it opens the valve fine and runs quiet. But when I tried running it off of another sprinkler wire or another station number on the controller it still buzzes.
Should I just replace the entire valve and assume the wiring is good? If it's replace, is there a way to get this off without cutting the pipe?
