When I attempted to start irrigation this season, zone 3 of 3 did not work. I thought that it might be th controller, because it was acting wacky (would not maintain date/time, program schedule, etc). So I purchased a new controller, however that did not solve the problem. I dug up the sprinklers (5 total). I noticed that there is water in the main line at 2 of the 5 sprinklers but the others are dry. There is no water pressure at all. Does anyone have any idea what the problem is?
