Anyone heard of this? I went to replace a sprinkler head to get better coverage. I took off the old, installed the new rotary head. When I turned on the zone, the flow was weak. So I took off the new head and cleaned it out and flushed the line. When I put the new head back on, no flow at all. I took off the new head and turned on the zone again. The OTHER heads working fine, but now I have NO water pressure to this head. What did I do wrong? How can I fix it? Thanks for your suggestions!
