Abstract
A water treatment or filtration unit is in two parts, a base and a cartridge. The base includes three ports, one of which may be selectively plugged or otherwise disabled. The cartridge contains the water treating material and is screwed into a socket in the base. Openings in the cartridge are then aligned with openings in the base to allow water to pass therethrough. Cartridges may be readily exchanged by simply unscrewing from, and screwing into, the base.
