How to Adjust an Orbit Professional Sprinkler Pattern

Orbit professional sprinklers are offered in pop-up and rotary or gear-driven models. Orbit professional gear-driven sprinklers provide for adjustments to the watering spray pattern and distance. The Orbit spray pattern is number of degrees or rotation the sprinkler turns. Gear-driven models operate on a manually set pattern. They are useful for watering larger areas without having to install additional fixed pop-up sprinklers. Adjusting the pattern on an Orbit professional sprinkler can help prevent lawn dry spots from forming.

  1. 1

    Find the fixed right edge. This is the right edge the Orbit sprinkler will not move beyond. With the sprinkler turned on, grab the top of the sprinkler or the turret and move it to the left and then to the right. When the sprinkler has ceased to turn right, you have found the fixed right edge.

  2. 2

    Turn the sprinkler body to align the fixed right edge. Grab the sprinkler body and turn it so the right edge lines up with where you want the sprinkler to start and stop watering in its rotation. This side of the sprinkler can only be adjusted by turning the sprinkler body. The left side can be adjusted with the pattern adjustment screw.

  3. 3

    Adjust the Orbit sprinkler's pattern. Insert the plastic end of Orbit adjustment key into the "pattern adjustment slot." This is an opening in the top of the sprinkler characterised by a small plus and minus sign on either side of it. Turn the adjust key clockwise to increase the sprinkler's rotation. Turning the key counterclockwise will decrease it. Each full turn of the key changes the rotation by 90 degrees. Turn the key as needed so the left edge or side starts and stops as the desired area.

Tips and warnings

  • Some Orbit pop-up professional models, such as the Adjustable Pattern 2-inch Pro Springloaded Pop-up, have a dial on the top of the sprinkler head that can be turned to adjust the pattern.
