Description

The AR (Annovi Reverberi) Kit 42369 is a heavy-duty unloader valve repair and rebuild kit specifically designed for the RSV series pumps operating at pressures above 3200 PSI. The unloader is the “brain” of your pressure washer, responsible for diverting water flow into bypass mode when the trigger gun is released.

This kit is essential for high-pressure RSV models where the standard unloader components may fail under the increased stress of 3200–4000 PSI operation.
