Abstract
A plurality of sanitary mixer fittings, in particular of concealed mixer fittings, form a set of mixer fittings that comprises identical universal connection housings with different cartridges and suitable different cartridges adapters. The universal housings have hot and cold water inlets for connection to the domestic water pipes as well as at least one mixed water outlet for connection e.g. to bath-tub inlets or showers. The relevant cartridge adapter is inserted into a location hole in the universal housings. The water inlets and outlets of the universal housings are flow-connected to water supply openings that are disposed in the inner surfaces of the adapter location hole in the universal housing. The water supply openings are flow-connected, optionally by annular chambers, to outer water supply openings in the outer surfaces of the relevant cartridge adapter. The relevant cartridge is inserted into a cartridge location hole in the relevant cartridge adapter. The water supply openings of the relevant cartridge are flow-connected to the inner water supply openings in the inner surface of the cartridge location hole of the relevant cartridge adapter. Provided in the relevant cartridge adapter are channels that connect the cartridge-side inner water supply openings of the cartridge adapter to the universal housing-side outer water supply openings of the cartridge adapter.
