A bib cock is a Y-shaped, wall-mounted tap with a curved downward-facing nozzle. While a bib cock may seem the same as regular taps, the bib cock has a specific design and mechanism, which make it suitable for specific applications. Typically made of brass, a bib cock is a plumbing valve that is used to control the flow of water from a supply pipe or drain. Bib cock taps are also called garden taps, because they are designed for outdoor use, generally have only one lever for controlling the flow of water, and can be easily connected to a hose. Bib cocks are wall-mounted valves that are used in commercial buildings, households, and industrial facilities.
