To achieve this goal most spray head zones (sprinklers that do not rotate) need to run approximately 15 minutes and rotor zones (sprinklers that do rotate) need to run approximately 45 minutes. If you have much slope on your lawn areas you may need to run 2 cycles but with shorter run times on the zones.
5. Observe the sprinkler zones as the water enters the pipes. The sprinkler zone that this open valve controls will have water flowing out of the riser at the end of the zone without a sprinkler head. Allow the water to flow for about five minutes to flush the system.. Mark each valve with a white paint marker to indicate a zone number that it operates. For future use, make a diagram of your sprinkler system on paper, showing the location of each valve box, each valve and the area it irrigates.
