We have a RainBird sprinkler system installed for lawn irrigation and I
was wondering ABOUT how long to run each zone to get 3/4 - 1 inch of
water. I know there's a ton of variables (water pressure, head type,
etc). But I'm looking where to start with the typical rotary (non
impact) head (T-Bird) doing a 180 degree sweep. My house has "normal"
water pressure and there are 4 heads/zone.


Put a bunch of tin cans out, water for an hour, and you'll know just how
much each area gets / hour.
