Ok, here is the deal. I am going to start putting irrigation on a baseball complex here in my home town in a couple weeks. The question I have is one service line big enough to feed four fields---one is a little league field----two are 310 in center and one is a major league style of field. I am getting 50GPM. And the pressure is about 50 also! I know I am going to need a pump how, should I lay it out. I want to tie them in to the same timer. Give me some advice!
