The exterior of the receptacle (21A) has a spiral groove (37) formed in a neck portion (38) thereof near its brim, and a peripheral flange (19A) at the lower end of that neck portion (38). The membranes (35A and 36A) are fitted for storage to retain moisture within the water treatment medium contained within the receptacle (21A). When the cartridge is to be installed, the membranes (35A and 36A) are removed and the cartridge is screwed into a respective opening in the base of a hopper, the peripheral flange (19A) forming a watertight seal with structure of the hopper.
