    Hi Gary,

       8 hours looks too much, you say total watering time so this means it's total time for 8 zones or less ? I see that is a program that runs "every 3 days" but I'd like to know more about your zone setup and sprinklers head used. The biggest increase in watering time is due to sprinkler head being configured with a lower precipitation rate than the real precipitation rate. Can you tell me the model of your sprinklers heads ?

    Nicholas,

    Hi Gary,

    I looked at your sprinkler head specs and it can do more than our default rotary one: https://www.orbitonline.com/site_files/manuals/55469-24%20rA(1)1.pdf

    To change our defaults go to zone properties and on the Sprinkler Head type select Custom and enter:

    Precipitation Rate: 0.5in/h 

    Application Efficiency: 0.8

    Let me know what timers you get. 

    To be more precise we would need:

    1. Exact sprinkler type (red, blue, green), 

    2. Area of each zone in square ft,

    3. number of sprinkers for each zone and their radius patterns (eg: 4 heads @ 180degrees, 1 @ 360 degrees etc)

    Hi Nicholas,

    Those figures provide much better times. Once the snow is off the lawn, I shall get the exact measurements, head count and type, I also plan to do an Orbit cup measurement since I have the 12 cups anyway.

    For now, the custom sprinkler has zone 1 down to 22min 5sec, about 1/6 the previous value.

    Thanks for the quick and accurate help! Once I have all the data I'll update the device and this post. That will likely be in a month.
