I guess I don't understand. If I want to put 1 inch of water on the lawn how does a different head accomplish anything different? If I want to do it slower, just run more cycles for less time. Instead of one 20 minute zone, run 4 five minutes on that zone. Not sure how any head will save water unless it puts less water. If all I want is less water, can do that today. What am I missing?
