There should be plenty of pressure, all of the rest of them come up. If you just tap the sticky ones, they will pop up.
I have several rotors that are stickey and refuse to pop up this spring. They will come up if you pull them by hand. The system is 1 yr old. They are Hunter I-20 stainless 4-inch. Any ideas
Has anybody heard anything bad about Hunter Rotors only watering the end of their arc and not having enough underspray to soak the grass underneath?
