Seems simple enough.. We moved into a new home in December and just getting sprinklers turned on, etc. Didn't see any obvious leaks after the first initial run, but the next morning I noticed the ground was wet around one of the sprinkler boxes. Open it up, box is nearly full of water. There are 3 valves in there, and it seems that 2 of them have a small drip coming from the main octagon shaped thing.. I'd wager it's 20 years old, but looks relatively easy to replace. Debating whether I start with just the solenoid, or diaphragm, or just do the whole valve.
Any experts with any tips?
