Abstract
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.
