Claim:
A fluid treatment system comprising: at least one non-treating flow-through tank for temporarily retaining a supply of fluid for subsequent use by the system; an inlet line leading to a first intersection; a first line leading from said first intersection to an interior of said tank; a second line leading from said first intersection to a side-stream treatment device configured for treating at least one of an untreated fluid from said inlet line and a treated fluid from said tank via said first line and selectively providing the treated fluid to said at least one flow-through tank; a third line leading from said treatment device to an interior of said tank for delivering said treated fluid to the interior of said tank; an outlet line connected to the interior of the tank for delivering water to a point of use; and at least one sensing device configured for sensing the quality of fluid in said at least one flow-through tank and being connected to said side-stream treatment device for providing the treated fluid to said at least one flow-through tank upon a determination of a quality of fluids in said at least one flow-through tank being less than or equal to a predetermined fluid quality threshold.
