I looked at it and thought about it. Looks like the top housing screws right off so you don’t have to mess with the piping. But it’s pretty buried in the box. I called my local irrigation guy. He’s going to come out and fix it for me. I told him to take his time since, at this rate, I won’t need water until June. But I do need some rain before the next mow. I tried to run the other zones with that zone stuck on and the pressure wasn’t high enough to pop all the heads.
