A soap dispensing system includes non-pressurized first and second soap containers connected to a soap manifold. The manifold has a first inlet connection to the first soap container and a second inlet connection to the second soap container. There is a soap outlet on the manifold. A soap conduit extends from a first dispensing opening on the manifold to a second dispensing opening on the manifold. A two direction peristaltic pump is associated with the soap conduit to move soap either from the first dispensing opening to the second dispensing opening or in the opposite direction. There are valves within the soap manifold for connecting the first inlet, first dispensing opening, second dispensing opening, second inlet opening, and the outlet to provide soap, upon operation of the pump, from one of said containers, through said soap conduit, to the manifold outlet.

1. A soap dispensing system including a first non-pressurized soap container and a second non-pressurized soap container, a soap manifold having a first inlet connection to said first soap container and a second inlet connection to said second soap container, a soap outlet from said soap manifold, a soap conduit extending from a first dispensing opening on said manifold to a second dispensing opening on said manifold, a two direction soap pump associated with said soap conduit to move soap either from said first dispensing opening to said second dispensing opening or from said second dispensing open to said first dispensing opening, valve means within said soap manifold for connecting said first inlet, first dispensing opening, second dispensing opening, second inlet opening, and said outlet to provide soap, upon operation of said pump, from one of said containers, through said soap conduit, to said manifold outlet. 2. The soap dispensing system of claim 1 wherein said two direction pump is a peristaltic pump, with said soap conduit extending about said peristaltic pump. 3. The soap dispensing system of claim 1 wherein said manifold valve means includes valve elements, movable between open and closed positions, and associated with said first inlet, said second inlet, and said outlet. 4. The soap dispensing system of claim 3 wherein said manifold includes first, second, third, fourth, and fifth soap chambers, with said first chamber being connected to said first inlet, said second chamber being connected to said second inlet, said third chamber being connected to said first dispensing opening, said fourth chamber being connected to said second dispensing opening, and said fifth chamber being connected to said outlet, said valve elements controlling communication between said chambers. 5. The soap dispensing system of claim 4 wherein each of said valve elements is spring biased to a normally closed position. 6. The soap dispensing system of claim 5 wherein there is a first normally closed valve element controlling communication between said first soap chamber and said third soap chamber, a second normally closed valve element controlling communication between said second soap chamber and said fourth soap chamber, and a pair of normally closed valve elements controlling communication between said third and fourth soap chambers and said fifth soap chamber. 7. The soap dispensing system of claim 6 wherein rotation of said pump in a first direction creates a pressure drop in said third soap chamber, opening said first valve element, to draw soap from said first container, into said first soap chamber and into said third soap chamber, passage of soap through said conduit, from said first dispensing opening, to said second dispensing opening, filling said fourth soap chamber, to open the valve element associated therewith to cause soap to flow from said fourth soap chamber, to said fifth soap chamber and to said soap outlet. 8. The soap dispensing system of claim 1 further including a control board and electric power connected thereto, an electrical connection from said control board to said pump, a first sensor associated with said first soap container, a second sensor associated with said second soap container, each of said sensors being connected to said control board and functioning to indicate a soap container empty/full condition. 9. The soap dispensing system of claim 8 wherein each of said sensors is located directly at a soap container. 10. The soap dispensing system of claim 8 wherein each of said sensors is located in a soap path between a soap container and said soap manifold.
