ABSTRACT:
A detergent mixing apparatus for use with a pressurized water source. The apparatus includes at least one mixing tank and a pair of liquid chemical supply containers each accommodating a liquid chemical composition. A water supply conduit connects a pressurized water source with the mixing tank. A pair of venturi chambers are disposed within the water supply conduit and are arranged for parallel flow. Each of the venturi chambers includes a suction port in fluid communication, respectively, with one of the liquid chemical supply containers so as to drawing the liquid chemical composition from each chemical supply container as pressurized water passes through the venturi chambers thus entraining the liquid chemical compositions in the water. A float-actuated control valve is operably connected to the water supply conduit for terminating the flow of water and entrained liquid chemical compositions through the water supply conduit when the liquid level in the mixing tank reaches a predetermined height.
