ABSTRACT:
A system and method for the prevention of bacterial growth in portions of a water treatment system which contain water from which bactericide has been removed includes a cross connect between the water containing the bactericide and the water from which the bactericide has been removed. The cross connect includes a check valve which closes to block communication between the respective waters when water is flowing through the system, and opens to permit diffusion of the bactericide from the water containing the bactericide to the water from which the bactericide has been removed when the flow of water through the system ceases.
