Why would the size of the zone determine the time of watering. I would think that larger zones have more heads and the heads have a set flow rate that would be the same in each zone.

I was running 17K gallons a month and discovered one zone was on for 40 minutes also the system was running twice a week. All used in irrigation

Changed it to all 15 minute run times and once a week - haven't got a new bill yet to see what effect the changes did to the consumption.

I did note that the water per gallon cost in Fla is about 1/2 what we pay in our area of Cali; however, the sewer is double the Cali rate - - - so it is about even for the two.
