The lid assembly (16) includes a housing (40) having apertures (66) therethrough communicating with the filter cartridge (C). A gate member (80) having apertures (88) is reciprocally movable between a first position wherein the apertures (88) in the gate member (80) are not aligned with the apertures (66) in the housing (40) and a second position wherein the apertures (88) in the gate member (80) are aligned with the apertures (66) in the housing (40). In the second position, water to be treated may be poured into the filter cartridge (C) through the apertures (66, 88) in the gate member (80) and the housing (40). Indicator means (140, 150) are provided and are movable incrementally in response to movement of the gate member (80). The indicator means (140, 150) move one increment during a cyclic movement of the gate member (80) from the first position to the second position and back to the first position. Movement of the indicator means (140, 150) is limited to a predetermined number of increments, the indicator mean (140, 150) preventing further movement of the gate member (80) upon reaching a predetermined number of increments.
