The resin content (2) of a water-softener cartridge (3) is regenerated by: attaching a collar (7) to the upper, perforated end (6) of the cartridge casing (4), arranged vertically, and placing salt (9) in the container so formed; and lowering the cartridge (3) into a receptacle (10) containing sufficient sort, still water (11) for the water to rise through the perforated bottom (5) of the cartridge (3) and immerse the entire resin content and part of the salt contained in the collar. The apparatus is left for the front of the saline solution formed in the collar to progress downwardly through the cartridge to regenerate the entire resin content thereof. |
