ABSTRACT:
A pressure washer wand having first and second valves that can be opened in a predetermined or user-adjustable manner through movement of a trigger. In one form, the first and second valves are opened sequentially in response to movement of a trigger to transition from a no-flow condition to a relatively low pressure flow and thereafter to a relatively high pressure flow. In another form, the sequencing of the valves can be changed such that only the first valve, which provides a relatively low pressure flow, is opened in response to movement of the trigger. A pressure washing system having the pressure washer wand is also provided.
