Abstract
A pressure washer includes a chassis as well as a liquid pump, a pump-driving prime mover, plural chemical product containers and a product selecting valve, all supported by the chassis. Each of the containers is attached to a separate valve conduit extending to the valve and the valve is connected to a device conduit extending to the mixing device. A distributor is mounted for movement with respect to the valve body and has a channel for selectively connecting one of the valve conduits to the device conduit. The user may thereby use the pressure washer to dispense any one of plural solutions. A fresh water container facilitates “wash out” of the valve and device conduit before switching to another chemical product.
