Summary:A self-contained, disposable water filter cartridge (10) for a water treatment system for treatment of potable water has one-way ball check valves (27,16) at the water inlet and water outlet to the cartridge. The generally cylindrical water filter cartridge is generally spherical on one end while substantially planar on the other end and is of a welded plastic construction. Asymmetrical lugs (32) radially disposed about the periphery of the planar end are adapted to mate with an apertured deck (65) of a water treatment system (70). The inlet ball check valve (27) is adapted to open under water pressure while the outlet ball check valve (16) is opened by a pin (9) when the cartridge is mounted on the deck (65). When the cartridge is removed from the deck, the check valves close to prevent water within the cartridge escaping.
