This is on a well with a pressure tank and switch.
Yesterday I interrupted the cycle to adjust the spray on a couple of heads in different zones which were hitting some bird feeders. I used the manual restart procedure I mentioned in my earlier posts, expecting to have to shut it off when it completed all zones and, lo and behold, when it finished all zones it didn't start over! I don't think I did anything differently. I'm going to experiment when I have time and try to figure out exactly what the deal is, but maybe I stumbled onto something.
