A dispenser connectable to a source of high fluid pressure and including a housing having therein a three-position cylindrical valve which controls both a main passageway and an auxiliary passageway. The main passsageway extends through the housing and the cylindrical valve. The auxiliary passageway extends from the main passageway, through the cylindrical valve, through a passageway between the housing and cylindrical valve, through a fluid reservoir on the bottom side of the housing. The cylindrical valve is manually rotatable by a control knob to an "off" position where the main passageway is closed, to a "soap" position where both the primary and auxiliary passageways are open, dispensing fluid such as soap from the reservoir, and lastly, to a "rinse" position where the primary passageway is open and the auxiliary passageway is closed.
