Irrigation should be performed between the hours of 4:00 pm and 10:00 am.
Always use less than 60 minutes per zone on your designated day. If you have an area of new grass or plants, you may water that area every day for the first 30 days, and every other day for the next 30 days (you may be asked to produce receipts to prove when grass/plants were purchased).
If you need to test your irrigation system you may do this at any time for up to 10 minutes per zone, but you must be present in the tested area during that time.
