ABSTRACT:
A low profile sprinkler head has a circular cup-like base with a threaded male coupling for attaching to a buried water supply pipe and an axial bore therethrough. The base includes a plurality of openings to permit sand and debris to fall therethrough. A removable nozzle head is provided for insertion into the bore. The nozzle head includes fluted water passages and various configurations may be provided to produce different water spray patterns. Nozzles are designed to produce a friction fit in the bore. The upper portion of the nozzle head has a curved underside which is disposed within the base to deflect the spray in a horizontal plane. The assembly is installed below the grass mowing level to permit mowing without damage to the sprinkler head.
