Only first sprinkler in zone is working


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

Best match for your symptoms are blockage or constriction. The first happens when dirt and rocks block a line somewhere downstream of a point where everything is working. The second is when tree roots grow around a pipe and choke it off. Blockage will be at a pipe fitting.
