Patent ID: 6973891

Claim:
A dual seal one-way self-closing drain plug apparatus for a boat comprising: a hollow body assembly having an inlet end and an outlet end thereof; a single chamber being located in said hollow body assembly between said inlet end and said outlet end; said chamber housing a valve assembly including a manual mechanism for opening and closing said valve assembly, wherein said manual mechanism includes a handle coupled to said valve assembly for opening and closing thereof, and said handle is shaped into a paddle that, when in the open position, is disposed perpendicular to the longitudinal axis of said boat, whereby said valve assembly is automatically closed when left open and when exposed to moving fluid caused by movement of said boat; said chamber also housing a safety device; and said safety device enabling fluid flow to occur in one direction and prevent fluid flow from an opposite direction by blocking access to said first chamber regardless of the position of said valve assembly; and said valve assembly including a shaft interacting with said safety device in such a manner as to move safety device into a closed position when the valve assembly is in the closed position, thereby creating a secondary seal.
