Yup, same thing here.
My system must’ve been designed back in the day of no water pressure because my 4,000sq ft back yard has 5 spray zones.
I started converting them to MP rotators, and the spray zones went from about 14min, to 50-60min with the rotators. It does make sense because the spray zones were putting out 1.5 - 1.8in/hr, and the MP rotators (pre-catch cup test) based on Hunter specs put out about .4in/hr. Putting down water MUCH slower, so the increased time.
So far so good. Even though they’re running almost an hour, the yard is NOT flooded. It’s about the same amount of water over the increased time.
