ABSTRACT:
The present invention is directed to a sprinkler head leveling for ensuring that the longitudinal axis of a sprinkler head assembly is substantially vertically aligned. The sprinkler head leveler uses a hollow cylindrical base which slides over the sprinkler head bonnet and external casing after the sprinkler head is inserted in the ground. A bull's-eye level is mounted to the base and disposed above a top surface of the base to provide clearance from the attachment hardware and embossments on the top of the sprinkler head assembly. In this way, the leveling device can be used to vertically align the sprinkler head assembly without interference from the surface of the bonnet and the surrounding ground.
