configuration with separate nozzles is simpler and allows you to connect to the water supply through a tube or let down firmly by means of flexible hoses.

inside surface of the cartridge openings closed with silicone or rubber gaskets.At the bottom of the upper washer has small grooves or notches to dampen sound vibrations and hammering.

characteristic breakdown in mixers with ceramic cartridge - a blockage between the ceramic plates, which is why the water is not completely cut off possible. Due to the fact that the cartridge is molded, it will have to change completely.
