Avoid using a combination of sprinkler types in a single irrigation station. Each sprinkler type distributes water at a different rate. Without uniform sprinkler types, you may find brown patches appear on your lawn. For example, pop up sprinklers generally take between 13 and 20 minutes to put down 10mm of water, while rotary sprinklers take up to 60 minutes to apply the same amount of water. If you are running this combination of sprinklers together, the areas covered by rotary sprinklers will never get the water they need.
