SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I have one line that refuses to turn on. I have replaced the entire manifold (3 times). The sprinklers will not come on manually or electrically. There are 2 heads that slowly leak. When I turn one the main water sometimes that line will spring into life all on it's own, then I manually turn the sprinklers "on" and they turn "off", go figure. Is this a pressure problem? Doesn't appear to be a broken line.

I can try to turn it around, however the other 2 valves are installed the same way I installed this one. The problem started when that line would not shut off at all, manually or electronically. I had to shut off the main valve, now I just can't it to work. Thanks for your reply.
