Generally speaking, the faucet is divided into four parts: water outlet, control, fixed and water inlet.
If it is divided according to the structure, the faucet can be divided into single type, double type and triple type. In addition, there is a distinction between single handle and double handle (also called single control and dual control).
Single type: cold water pipe or hot water pipe can be connected;
Duplex: It can connect hot and cold two pipes at the same time, which is mostly used in the bathroom basin and the faucet of the kitchen sink with hot water supply;
Triple type: In addition to connecting the cold and hot water pipes, it can also be connected to a shower head, mainly used for bathtub faucets.
Double handles: The cold water pipe and the hot water pipe need to be adjusted separately to adjust the water temperature.
If these two structures are combined, there will be our common choices of single-unit single-control, double-unit single-control, double-unit dual-control faucets, etc. How to choose depends on the location and habits of use.
