Abstract
A valve in a fluid treatment system adapted for controlling the flow of fluid between a source and a treatment media disposed in a treatment chamber. The valve includes a housing having a fluid passageway between an inlet and an outlet; a containment chamber; and a sealing member reciprocal between a first position in which the sealing member is retained in the containment chamber out of the flow of fluid in the passageway and a second position that seals the outlet. The containment chamber also includes a drain opening, which can be a venturi, for emptying the containment chamber of fluid.
