Abstract
An apparatus and method for injecting a chemical upstream of a pressure washer includes an injector valve comprising a housing having a passageway through which the wash stream flows. The injector is installed upstream of the pressure washer pump. A chemical inlet is formed downstream from an adjustable orifice which causes the chemical to be drawn into the passageway through the chemical inlet. The injector also includes a plunger in which the adjustable orifice is formed. By moving the plunger, the passageway can be opened or blocked allowing the chemical to be selectively injected into the wash stream.
