ABSTRACT:
This invention relates to an adjustable riser member mounted between a buried inlet water supply line and a yard sprinkler head as part of an overall water sprinkler head. The adjustable riser member includes (1) a main support body assembly; (2) a riser assembly mounted in the main support body assembly for longitudinal movement therein; (3) a threaded support assembly mounted in the main support body assembly; and (4) a seal assembly mounted on a top portion of the main support body assembly. The support water enters a lower end of the main support body assembly and flows through an upper end of the riser assembly for discharge into the yard sprinkler head. The riser assembly is rotatable in the threaded support assembly for longitudinal adjustment thereof with the seal assembly preventing any water leakage from the main support body assembly.
