I have a customer getting ready to start installing a large pond. He wants to irrigate the hillside above it out of the pond. This is a large area, I would guess about 3-4 acres of large trees and grass. So what kind of components would you use? I'm thinking submersible, filter, 2" valves. But not sure what heads. Plenty of area to work with so they should be large area. He asked me about golf course heads. Which ones have you guys had experience with?
