How to Adjust Orbit Sprinkler Heads

Updated February 21, 2017

Orbit manufactures sprinkler heads for residential and commercial use. Sprinkler heads are available in spray and rotary-head types. Spray-head models include pop-up and fan heads. Rotary-head sprinklers are gear driven or impact. Adjusting Orbit sprinkler heads will help keep watering areas lush and green.

Identify the type of Orbit sprinkler head you have. Rotary-sprinkler heads can turn or rotate when operating. Spray-head sprinklers remain stationary. Identifying what type of sprinkler-head you have will aid in making adjustments.

Turn the distance-adjustment screw with a screwdriver. This screw is located on top of the Orbit sprinkler head, towards the spray opening. It adjusts the watering radius. Turning the distance-adjustment screw clockwise will decrease the radius. Turning it counterclockwise will have the opposite effect.

Turn the pattern-adjustment screw with a screwdriver. This screw is only found on Orbit rotary-sprinkler heads. The pattern-adjustment screw changes the watering arc, or how many degrees the Orbit sprinkler head turns. The arc can typically be adjusted from 40 to 360 degrees. Each full turn of the pattern-adjustment screw changes the arc by 90 degrees. Small plus and minus symbols indicate which way to turn to increase or decrease the sprinkler head's arc.


Some sprinkler models have an adjustment key, which is used in lieu of a screwdriver to make adjustments.


Turning the radius-adjustment screw too far clockwise or counterclockwise can cause it to come out.
