ABSTRACT:
An apparatus for use with a water treatment unit and in particular, those having a treatment cartridge, that indicates the end of life of the unit. The apparatus comprises a housing with at least one opening for the passage of liquid to a chamber, formed by the interior of the housing and the water treatment unit. The chamber includes a support member mounted to the housing. A float is rotationally mounted on the support member. The support member limits float movement to a predetermined distance upon each rotation of the float, resulting from each cycle (use) of the water treatment unit. Once the float has made a specific number of rotations and has travelled the complete distance of the support member (as water fills and drains from the chamber), the float rests in a position where it is visible through an opening in the housing, indicative of the end of life of the water treatment unit.
