Sprinkler head type determines the flow rate of a zone, or how much water a sprinkler can deliver to your plants over a given duration. Certain head types have high flow rates, and can irrigate your yard quickly, while other types are slower and take longer to provide the same amount of water.
Below are the head types you can choose from.
 |
Surface Drip: (0.5in/hr) Drip irrigation delivers water to precise locations. This type is suitable for watering individual plants in a vegetable garden, or running lines to the bases of trees and shrubs. Different drip systems have different flow rates |
 |
Bubblers: (1.0in/hr) Bubblers are similar to surface drip systems, but produce a steady stream of water instead of droplets at a time. Bubblers have a limited range, and like drips, should be used to precision-water the roots of individual plants. |
 |
Pop-up Spray: (1.4in/hr) A pop up or spray system delivers a high volume of water to a wide area. These will water your zones the quickest due to their high flow rate, spraying a thick mist. |
 |
Rotors Low Rate: (0.35in/hr) Rotors have the largest effective radius, but due to the size of the area they cover, take the longest to finish. These sprinkler types are good for wide open yards
|
|
Rotors High Rate: (0.9in/hr) Rotors have the largest effective radius, but due to the size of the area they cover, take the longest to finish. These sprinkler types are good for wide open yards. High rate rotors are usually available on newer models (2017 onward).

Custom: You can also tune your sprinkler head type with your own data. Custom uses Precipitation Rate and Application Rate as user defined variables. Precipitation rate is basically the inches of water delivered to an area, and Application Rate is the flow rate over an area.
