I am trying to dial in my system Rachio 3 precipitation rates. I have 4 Rainbird 5000 each with a 1.5 gpm nozzle. So each zone puts out 6.84 gpm. I’m on a well with a 6.5 gpm refill. I do have 200 feet of reserve in my well. So I can go over the 6.5 a little bit safely.
I was using the formula of 96.25 x 6.84/ sq feet
My question is I can’t accurately get sq ft per zone as the heads are not in a perfect square or straight line etc. so it’s hard to accurately measure.
What I did though was measure my front yard. Then I have 6 zones covering the front yard. I split the sq feet for the whole front yard by 6 and used that number in my formula. Is this correct? Or should I try to get individual zones some how. I should not that I do have head to head coverage.
