So, I've been playing around with plotting my sprinkler system heads and zones. I was thinking about using Hunter I-20's with precipitation matched nozzles for the large areas and haven't decided what I should use for the lower section of the diagram. I have about a 12ft section between the house and the property line. I have thick skin so feel free to tear apart my design. I tried dividing the property into rectangular sections but I have trouble "joining" the sections together to get even coverage. I only have 7.25GPM @ 59psi coming out of my outdoor spigot which is kind of worrisome. It does go from 1" PEX to a peice of 6 foot 1/2" PEX before it reaches the spigot. Maybe that explains my low GPM. I'm hoping I can get at least 4 heads on each zone with a 1" main line.
