1. A pressure washer wand comprising:

  • a housing having a pistol-grip handle and a trigger guard;

    a valve assembly housed in the housing, the valve assembly including a first valve and a second valve, each of the first and second valves including a valve member that is movable between a closed position and an open position, each valve member being biased toward the closed position;

    a first outlet in fluid communication with the first valve;

    a second outlet in fluid communication with the second valve; and

    a trigger coupled to the housing between the pistol grip handle and the trigger guard and movable between a first position and a second position, the trigger having a first cam and a second cam, the first and second cams being configured to move the valve members of the first and second valves, respectfully;

    wherein moving the trigger from the first position to a first intermediate position between the first and second positions opens a first fluid communication pathway from the first valve to the first outlet, positioning the trigger in a second intermediate position between the first intermediate position and the second position opens a second fluid communication pathway from the second valve to the second outlet such that both the first and second fluid communication pathways are opened, and positioning the trigger in the second position closes the first communication pathway from the first valve to the first outlet while maintaining the second fluid communication pathway from the second valve to the second outlet open.
