Thread: How to change the spinkler pattern?

    Default How to change the spinkler pattern?

    Hi have a Rainbird model 21AP00 sprinkler head. It currently sprays at 180 degrees. I would like to do 2 things:

    1. Make the sprinkler head to spray 360 degrees.
    2. Make the spray distance further.

    Can you help?

    A quick Google search shows that the 21AP is a rotary impact head. The RB impacts that I am familiar with can easily be adjusted to any degree of circle you wish, and by simply flipping the wire trip upward will operate full circle. The distance they will throw is regulated by adjusting a screw the the water stream passes. I have not actually seen this model, but I have to believe it would be similar.

    The 21AP seems to be listed as a Full Circle Rotor....it may not be adjustable. http://www.rainbird.com/pdf/turf/ts_...651_Series.pdf

    Default Thanks

    Guys thanks for the information. I figured out that you have to take a small band off the sprinkler while it is on. Once you have that you push down on the sprinkler head and twist it 90 degrees until you find tha pattern you want. It was rather easy once I figured that out. Thanks for the help!
