A two-chambered water softener tank with a bi-directional valve for controlling the flow of water between the chamber for use with a water softener is disclosed. The tank includes an outer shell, an upper chamber located within the outer shell containing a redox medium, a lower chamber located within the outer shell and beneath the upper chamber that contains an ion exchange resin, a first port allowing water to flow into the upper chamber, a second port allowing water to flow into the lower chamber, and a third port for allowing water to flow between the upper chamber and lower chamber. The water softener tank also includes a bi-directional valve engageable with the third port for regulating flow of water through the third port from the upper chamber to the lower chamber during service of the water softener and from the lower chamber to the upper chamber during regeneration of the water softener. The bi-directional valve remains open as water flows from the upper chamber to the lower chamber. The bi-directional valve floats upwards to restrict the flow of water through the third port from the lower chamber to the upper chamber during regeneration, thereby creating a high pressure flow of water during the regeneration of the water softener to clean the redox medium, such as KDF. |
