The present invention provides a system featuring a dispenser for providing fluid from multiple reservoirs to an appliance or other suitable device; and a multiple tubing arrangement coupled between the dispenser and the multiple reservoirs of fluid, the multiple tubing arrangement being responsive to a vacuum provided from the dispenser, for drawing the fluid from the multiple reservoirs so as to deplete the multiple reservoirs at relatively equal amounts based on the Venturi effect. The multiple tubing arrangement comprises a primary inlet tube for arranging in a primary reservoir, an auxiliary inlet tube for arranging in an auxiliary reservoir, and a feed connector tube arranged between the primary inlet tube and auxiliary inlet tube. The primary inlet tube is coupled to the auxiliary inlet tube so as to provide a proportional vacuum and siphoning effect. The multiple tubing arrangement siphons and depletes the fluid from the primary reservoir and the auxiliary reservoir based on the Venturi effect.
