I have a 6 zone pop up sprinkler system. Five of the six zones work perfectly. The sixth doesn't I and I'm hoping you guys can help me figure out what's wrong. When the sixth zone is activated there doesn't appear to be enough water pressure to make the sprinkler heads pop up. There is water flowing in the pipes because water dribbles out of the unpopped sprinkler heads. I thought that I had a leak in the pipe because there's a significant saturated wet spot in one area of the lawn. However, I dug out the pipe everywhere around that spot and I there's no leak there. I'm thinking that the saturated wet spot is just from the water dribbling out of one of the sprinkler heads that isn't going up. I have no idea, however, why there isn't enough water pressure anymore for this zone. What could be the problem be from and what do I do to confirm the diagnosis? Thanks very much!!
