Zusammenfassung:	An eductor for mixing two liquids wherein the eductor includes a closed or non-air gap back flow prevention member. The vacuum profile of the eductor is altered by changing an opening in a passage portion to controllably divert water flow around the venturi tube or diverting the water without the opening. This affords the changing of the vacuum profile without redesigning the entire eductor.
