I've just finished installing my lawn, irrigation system, and new RainMachine Mini-8. I'm in the seeded phase so I can't really use it to it's full potential currently. Regardless, I did a trial run (supply valve off) of my program that will be used once the grass is fully in.
In certain zones I'm using rotors with big nozzles since I have plenty of GPM from my 1" main @ 75psi. These zones have calculated precipitation rates between 0.45-0.56in/hr. All three zones are flat and have either silty clay or clay loam.
With the Cycle & Soak set to Auto I expected zones 1-3 to not run for their full amount of time and instead transition to zones 4 and 5 while the ground soaked up the water. That didn't happen on my trial run.
I know if zones 1-3 run for their full amount of time I'll end up with a lot of standing water and runoff. From what I could find, my soil types in these zones will absorb 0.2-0.3" in/hr. With my precipitation rates nearly double that, why didn't Cycle & Soak work in Auto?
