My lawn irrigation system has been extensively rebuilt in recent years in preparation for expansion. The small lawn in front of the office on the east side should be incorporated into the existing lawn irrigation system in a timely manner. I had already calculated the position of the sprinklers. The area is relatively small, about 10 x 10 meters. Irrigation with the previously installed Hunter i20 sprinklers did not seem very effective to me. I have therefore dealt with more in-depth with the so-called rotator bursts.
