Abstract

A unitary multi-function control module 18 for a reverse osmosis water purification system provides all of the necessary flow control functions in a single removable and easily replaceable unit. The module connects directly with a unitary injection molded manifold 14 and includes a control housing having a cover plate 42, a main body 40, and a closure plate 47. The control housing entirely encloses therein the supply flow shutoff valve 46, the reverse osmosis flow control 100, the permeate back flow check valve 82, and all of the interconnections between the manifold and the supply, permeate, and brine flow paths.
