    I am running the valve test cycle on the esp RB contorller. Everything seems ok, but one zone of Hunter rotors pop ups runs and continue to work at 10-20% after controller goes to the next zone. They stay slightly popped up at the last zone number 21. Is the Valve stuck?

    Also, I have some rotors near a driveway. Any advice on cement doughnuts?

    Got carried away with fishing on last thread so starting new one for new problem.

    I don't know if you liked my other answer but I will try this one. The valve is either sticking or maybe if it in a hilly area it is draining and that can keep heads up for maybe a few minutes. Shut the water off take the top off the valve and see if there is any debris (gravel/sand) in it. If not and still sticking go get a new valve exactly like yours take the top off and just replace the top.

    I am going to try to clean it. It is at a place where the ground begins a slope toward a lake.

    It is just the zone draing. This is normal for any zones on a slope.
