i would be very surprised if your pr is over 1.5
My pr calc comes out at 1.69.
96.25*18/1020
But impossible to know real GPM from these …
Now I think your flex schedule run times will be much more accurate, what are your run times after you make a custom nozzle with that pr?
I went with 1.2
After I dial it back to 50% I get 13 minutes run time but not every day. And since I ran the zones a bit uneven yesterday the moisture levels aren’t even. I think I will leave it as is now and monitor.
What grass do you have?
I run my mad at 90% to keep me at about 7-9 days of watering, it will get shorter in peak heat, but you gotta stretch those roots if you can…
