So I figured the hardest part of my irrigation system would be all the digging, but here I am, lost and confused with setting up my zones!
I want to make sure I'm doing this right with my first zone before working through the other 7. I have all Rain Bird heads in my setup, combination of rotors and fixed spray. The front yard is the most basic setup, 6 rotors total. Each head has a different nozzle from .75 GPM to 1.5 GMP. If you average them out, it is 1 GPM per head, 6 GPM total for the zone. I understand that the PR formula uses Number of heads, GPM flow per head, and the zone square footage in its equation. To create a custom nozzle for the front yard I have figured PR = 6 heads * 1 GPM (average) divided by 744sqft area to give me .776 inches per hour.
Now, when you configure the zone, I give it the area again, and also tell it which nozzle I am using. My confusion comes from having to enter the area twice, then also having an Efficiency value in the zone setup. Is my math correct? Will calculating the PR for each zone individually give me good results with using the Flexible Daily schedule?
Otherwise having a great time with this project, yard work and IT work are a fun combination for me!
