I just got my Rainmachine a couple weeks ago and absolutely love it.....what an amazing product!
I am writing because I am noticing that my system is barely running, even though we had little rain this week and temps in the upper 90s. I have always rain my system 3 days a week X 40 minutes per zone. When I setup my rainmachine it was suggesting a 2 hours+ per zone, so I adjusted this down to 35% to get close to where I was.
I do have area and GPM setup, but I am using the default rotor PR of .35. I know changing this to .5 will make a difference, but the suggested time is still going to be much higher than I am used to. I looked up my rainbird rotors and the PR rate is listing .37-.72, so this is not very helpful.
That said, I notice that the system is only running 25-50% most days, so should I just use the suggested time and not worry about it?
