On the RPS75i model rotor there is also a flow control that can be used in addition to or independently from the nozzle retention/break up screw described in the adjustment above. The flow control is located at the 5 o’clock position in relation to the nozzle arrow’s 12 o’clock position, insert the “T” shaped end of the RPS key into the hole over the flow control. Turning the key clockwise will reduce the flow and distance proportionately up to 50% however can be used to adjust the distance below 50% with the fully counter clockwise position being off/no flow. The riser will still pop up but no water will come out with the flow control off.
