Diverter is a plumbing device that redirects the flow of water from one outlet to another. It is commonly used in showers or bathtub fixtures to control where the water is directed. The diverter typically consists of a valve or lever mechanism that, when operated, redirects the water flow between different outlets, such as a shower head and a bathtub spout. This allows users to switch between different water delivery options, providing flexibility in how water is utilized in a bathroom. Diverter valves are crucial in modern shower systems, enabling users to enjoy a variety of bathing experiences with ease and convenience.
