I just installed my first irrigation system. 33 I-20, 18 pro spray's, 7 jar-top valves and a drip line for the beds. I did it by myself in 4.5 days. It was great to get away from mowing for a week. Anyway, we just laid the sod, so i programmed the clock, Pro-C, and set the spray heads for 20min and the rotors at 40 min. Then when i switched it to RUN zone one ran for 1hr15min? What did i do wrong?
