Thermostatic sink tap is an essential part of a well-thought-out hydraulic plant. Usually, this comfortable and cheap solution is installed inside the showers because it helps to protect ourselves from the accidental burns, due to hot water. All the thermostatic blenders are made to maintain the water temperature constancy, during all duration of the shower by modulating also the extent of water in case of an unexpected initiating. Thanks to the presence of the thermostatic valve, the thermostatic tap blends hot and cold water in order to reach the preset temperature. In case of an interruption of cold water supply, thermostatic valve will lock automatically.
