* The in-stem flow regulator is adjustable, which enables the flow and 
    pressure through the IFR pop-up stem or the IFR Coupling or Riser extender 
    to be regulated to the desired distance of throw for the
    Precision Roating Nozzle and the Precision Series Spray Nozzles.
    This adjustment to the desired distance of throw results in the stated
    gpm flows shown in the charts above.
