1. A solution storage and dispensing apparatus, comprising:
- (a) first and second containers, each having first and second inlet ports for receiving water and a chemical concentrate, respectively, the first and second inlet ports being in fluid communication with a proportioning means, outletting into the container, for proportioning the relative flow rates through the first and second inlet ports;
(b) a selector valve having an input and first and second outputs, the first and second outputs in fluid communication with the first inlet ports of the first and second containers, respectively, wherein the selector valve is selectable between first and second positions for placing the input in fluid communication with the first and second outputs, respectively; and
(c) a control valve, in fluid communication with a water source, for selectively controlling the flow of water to the selector valve, wherein the control valve is not connected to a source of electricity.

Abstract
A solution storage and dispensing apparatus and method of operation therefor are disclosed. The solution storage and dispensing apparatus includes a selector valve and a control valve which selectively output a liquid such as water to one of a plurality of storage containers. Each container has an aspirator mounted therein which receives the water and a chemical concentrate to form a solution therein. A container is filled by selecting the container using the selector valve and actuating the control valve to dispense water to the selected container.

13. A method for filling containers, comprising the steps of:
-
(a) providing a plurality of containers, each having first and second inlet ports for receiving water and a chemical concentrate, respectively, the first and second inlet ports being in fluid communication with a proportioning means, outletting into the container, for proportioning the relative flow rates through the first and second inlet ports; (b) selecting one of the containers to fill by selecting one of a plurality of positions of a selector valve having an input and a plurality of outputs, at least a portion of which are in fluid communication with the first inlet ports of the containers;
whereby the input to the selector valve is placed in fluid communication with the selected container when the selector valve is in the selected position; and(c) manually actuating a control valve disposed in fluid communication between a water source and the input of the selector valve to dispense water through the selector valve, and thereby dispense water and chemical concentrate into the selected container, wherein the control valve is not connected to a source of electricity. - View Dependent Claims (14, 15, 16, 17)

18. An apparatus, comprising:
-
(a) a plurality of proportioning means, each having first and second inlet ports in fluid communication with an outlet port, and each for proportioning the relative flow rates of fluid through the first and second inlet ports, wherein the second inlet port of each proportioning means receives a chemical concentrate; (b) a selector valve having an input and a plurality of outputs, each output in fluid communication with the first inlet port of one of the proportioning means, wherein the selector valve is selectable between a plurality of positions for placing the input in fluid communication with one of the plurality of outputs, respectively; and (c) a control valve, in fluid communication with a water source, for selectively controlling the flow of water to the selector valve, wherein the control valve is not connected to a source of electricity. - View Dependent Claims (19)
