OEM Krānzle Unloader Replacement Kit for AZ and AZ-L Pumps used on 1122 1322 1622 machines. The Krānzle Unloader Replacement Kit ensures consistent pressure regulation and protects your pressure washer pump from potential damage. With its automatic valve mechanism, it redirects water flow away from the nozzle, preventing pressure build-up and allowing the pump to run smoothly. While an unloader can adjust the pressure output of your machine, it is advised that pressure output only be handled by your selection of pressure washer tips. If the pressure washer experiences sudden pressure drops or erratic behavior when releasing the trigger, it could indicate a faulty unloader valve.
