Abstract
An adjustable sprinkler system includes a plurality of sprinkler units disposed about an area to receive water. Each sprinkler unit includes a tapered base portion driven into the earth, and a pair of connector nipples to receive and retain flexible tubing which connects the sprinkler units and supplies water under pressure thereto. Each sprinkler unit includes a cylindrical member extending upwardly from the tapered base portion, with a cap threaded onto the exterior of the cylindrical portion. An arbor is received in a bore in the cylindrical member and is secured pivotally therein. The arbor is rotatable to adjust the rate of flow of water from the sprinkler, while the cap is rotatable independently to vary the spray pattern issuing from each sprinkler.
