Look at the bottom of the nozzle. Is the small round inlet hole blocked by anything?
• If you found dirt in the screen or nozzle you should flush out the pipes again. 90% of the time this problem has been caused by dirt left in the pipes that then clogged the heads. See the next question for how to flush out the pipes. • Check for anything that could be blocking the flow through the sprinklers. Maybe they had a manufacturing problem. I’ve experienced this from time to time with almost every company’s products. A plastic mold gets out of adjustment at the factory and leaves a glob of plastic in the wrong place. Yes, they should catch it at the factory! • If all else fails, brainstorm and check out everything and send me every little detail you can think of. Maybe something that seems unimportant to you will mean something to me!
