I just swapped out my old brass heads for Hunter sprays with MP3000 heads. While the literature states 30 feet at 35psi, I realized that I probably wouldn't get that in real life conditions. What I wasn't expecting was only getting 15-16 feet radial distance. The heads are installed in a fenced in yard with a lot of trees in the neighborhood, so wind isn't a factor. Has anyone else had similar problems? I just realized as I was typing this the MPs have an adjustment screw on them. But don't they come set all the way open?
