faucet

This term primarily describes the mechanical hardware used to regulate water flow in domestic settings. In North American English, it is the standard term, whereas British English typically employs the word tap for the same object. When used figuratively, the word evokes the image of a valve being opened or closed to control the volume of a resource. It suggests a deliberate regulation of supply, often referring to money, information, or power, where the "flow" can be abruptly stopped or increased.
