ABSTRACT:
A process for raising a sunken, in-ground sprinkler is provided. In the first step of this process, which is especially useful with pop-up sprinklers, the area around the top of the sprinkler is first cleared. Thereafter, the motor compartment structure and the rotatable sprinkler head are removed from the sprinkler housing. A circular sleeve adaptor is then attached to the sprinkler housing, and a threaded shaft is then attached to the adaptor. A support platform, with a hole in its middle, is then placed over the sprinkler, and one end of the threaded shaft is placed through the hole. A wing nut is then attached to the threaded shaft, and the rotation of the wing nut causes it to contact the top of the support platform, thereby raising the sprinkler assembly.
