In plumbing, a tap, also known as a faucet, is a device that controls the flow of liquid, typically water, from a plumbing system. Taps are commonly found in kitchens, bathrooms, and other areas where water access is needed. They usually consist of a valve or handle that, when turned, opens or closes a passage to regulate the flow of water. Taps come in various designs and styles to accommodate different preferences and needs, ranging from traditional knob-style handles to modern touchless sensors.
