ABSTRACT:
The invention is a dual tank dispensing system that provides for directional control of the fluid being dispensed. Flow may be diverted through various pathways in order to provide different flow modes including: normal delivery, backwashing, rinsing, and isolation of one of the tanks. A unique dual diverter valve unit provides for alternate flow arrangements through passages in a body that connect the two tanks to the source of water. Each valve is in connection with four passages and through rotation of these valves various pathways are created that lead the flow to be diverted through one or both tanks and through an outlet passage leading to the destination or through one of two passages that allow for either rinse or backwash. A detector may be used in connection with the control unit to determine that the filters are clogged and signals the system to being a backwashing operation. The control unit rotates one or both valves a certain degree that changes the direction of flow and allows a reverse flow through one of the tanks. Other movements of the valves may be used to direct the flow normally through the tank but not to the final destination (rinse mode) and/or shutting off flow to one tank entirely (disconnect mode).
