  • an elongated stem having an inlet supported within said base;

    a nozzle supported within the stem;

    a water distribution plate supported on one end of a shaft extending upwardly from said base, said water distribution plate located in axially spaced relationship to said nozzle and adapted to be impinged by a stream emitted from the nozzle,an externally threaded sleeve fixed to an opposite end of the shaft andan elastomeric throttle control member constructed with a smooth through-bore, engaged over said externally threaded sleeve but prevented from rotating such that rotation of said shaft causes said throttle control member to move axially relative to a flow restriction portion in said inlet, to thereby adjust flow rate through said stem and said nozzle.
