Karl, Not one drop of water seems a pretty severe requirement. It is difficult to find a check valve that does that unless, perhaps, it's built like the check valves in blood vessels. Can you reach the discharge port in your deck? If so, one approach might be to cap or plug it from the outside and manually remove the cap/plug as needed.
