How Long to Water
Every irrigation system is different. Several factors determine the amount of time needed to supply the proper amount of water, such as type of irrigation head, size of the nozzle, water pressure, and the coverage area. As a general rule, rotor zones need to run between 30 minutes to 1 hour per zone to get ½ “ of water. Spray zones should run 5 to 10 minutes per zone to get a ½ “ of water. You will need to measure the amount of water your irrigation system is putting out in each zone to see how long your system needs to run. A rain gauge can be placed on the lawn to measure water output.
