Abstract
A dilution apparatus includes a container having an adjustable float-operated make-up valve wherein the make-up valve has an inlet end connected to a water supply tube and an outlet end connected to a fill tube inside the container. The make-up valve is connected to a float disposed inside the container. The water supply tube is connected to a reservoir that contains a concentrate. The water flow through the water supply tube siphons the concentrate, into the water stream and through the make-up valve to form a first dilution. A proportioner is connected to a water supply and to the bottom of the container. The water flow through the proportioner siphons the first dilution into the proportioner, thereby mixing the first dilution with water to form a final product having a predetermined dilution ratio.
