If your MP Rotator Nozzle is not rotating, there may be debris in the nozzle. Remove the nozzle to inspect and clean the filter screen. Replace the nozzle and turn the valve on to run the sprinklers. Increase the radius to its largest adjustment by turning the center screw four full turns counterclockwise. Then adjust the arc adjustment ring to its largest arc by turning it clockwise. You may have to open and close the arc adjustment several times to pass the debris.
MP Rotator Nozzles also rely on the incoming pressure of the water passing through the nozzle to produce rotation of the top portion of the nozzle. If this pressure is restricted, it can result in slow or no rotation. MP Rotator Nozzles perform optimally at 40 PSI (2.8 bar; 280 kPa). Take a pressure reading at the head with an MP Rotator Gauge to ensure there is a sufficient pressure supply.
