SHUT-OFF VALVE ABSTRACT OF THE INVENTION A plastic spring loaded shut-off valve for drains in live wells of boats seals without the presence of fluid pressure. This effect is achieved by a biasing spring urging sealing flaps against the valve ports. The flaps are curved and have ribbed edges to accomplish such sealing and prevent jamming of the ports. The biasing spring is secured to a rotating member through slots while the flaps are secured to the member by buttons. The spring and flap are also secured by a bar across the flap, which has a bearing pad where it is contacted by the spring. The rotating member is rotatable on the underside of the valve top screwed to the valve body. Stops on the inside of the valve top limit its rotation.
