Only first sprinkler in zone is working
Hello,
I recently did some updates on my sprinkler system and everything was working great until today. When I went to turn on a particular zone the first head pops up and works great but the rest don't. The same happens if I manually turn on the system. This zone has only 4 rotors. I dont see a leak anywhere on the line. The should mention that the remaining 3 heads have a little water trickling out. Not sure what the problem is. The valve is new. The rest of my zones work. A similar thing happened with this zone once but then the next time I turned it on it happened to work. Any advice would be very appreciated.
Thank you
