This valve is used to prevent the reverse flow of water. It is commonly used in installations where the filtration system is located below the water line. The valve prevents backflow that could escape from pumps or other equipment when they are opened for maintenance. Another common use is found in pools with overflowing spas or coping, where it prevents water from flowing from a high point to a low point when the pump stops.
