Invented in 1880 by Thomas Campbell, Mixer Taps are commonly used in kitchens and bathrooms and can be fitted to various types of sink and/or basin. They work by combining the water from the hot and cold valves together so that they come out through the same outlet, thus mixing the two together. This creates a stream of water that will be at a temperature in between the hot and the cold which is more bearable against the skin when washing.
Mono Bloc Mixers typically have a single lever that is lifted up to control the flow of water from both the hot and cold supplies; the higher the lever is pulled up, the more water flows through. Turning the lever left and right will adjust the temperature.
Deck Mounted Mixers are similar to Filler Taps, in that the taps and the outlet are all connected to create one large piece, rather separate pieces like traditional taps or one piece that incorporates everything upwards, like a Mono Bloc Mixers.
