ABSTRACT:
A water treatment device including an arrangement having mechanisms for mechanically totaling the volume of water filtered and for indicating when the replaceable filter cartridge has reached the end of its useful life. End-of-life indication is provided by a valve mechanism for stopping flow after a predetermined volume has been filtered. The arrangement includes a novel mechanism for resetting the flow totalization mechanism. The preferred water treatment device is faucet mounted and also includes a novel flow bypass design.
