I'm getting ready to tear-up and re-install an irrigation system in a small city park. The pump pressure is not the greatest on earth, and I was considering installing some 360 adj. 4" low volume pop-up sprinklers in some of the smaller areas with St.Augustine grass. Something along the lines of the Hunter MP rotators. I'm looking for something with a 10-12' radius. I have not messed with these very much in the past, so do you all have any brand/model recommendations ?
