The hose connecting unit includes a flow directing valve selectively operable to direct the water source (1) directly to the spray tank; or (2) through the portable unit. The portable unit includes a flow path having therein a flow control valve, a rinse water valve, and a venturi communicating with a chemical withdrawing conduit enterable within a chemical container, and a rinse water directing mechanism under the control of the rinse water valve cooperating with the chemical withdrawing conduit.
