Hunter sprinkler head adjusting...

I googled Hunter sprinkler heads and where to purchase them. In my area (the East bay, Tri-Valley) in Nothern California.

I went to Ewing Irrigation in Dublin, CA and found the Hunter sprinkler heads there. The man working the counter got two for me and he demonstrated how to change the head by unscrewing it from the base at or just below ground level by removing the old one and screwing in the new head. He also showed me how to adjust them with the spray pattern. You will need the little tool that comes with the sprayer head.

Making sure the center arrow is completely to the left and rotate the head to the right then back to left. They are set to a 180% spray pattern from the manufacturer. If you want a bigger pattern you turn the adjuster toward the ( + ) side and if you want less pattern you turn the adjuster to the ( - ) side. He showed me how to install the red sprayer inserts by simply pushing them in the cavity making sure the little u shaped indentation is pointing up to allow for the set screw to go through to adjust the spary.The spray varies in distance and amount of water being emitted from the head depending upon the insert used.

I was able to replace the Hunter head, adjust the spray and changed out the insert a few times until I found the one I liked. I used needle nose pliers to remove the initial spray insert that the man @ Ewing installed until I found the one that worked best.

I found using needle nose pliers makes it very easy to grasp the little inserts for replacing.
