Water Coming In

Hopefully you've figured this one out by now, but just in case....
I noticed recently that whenever I stop my boat on the water, some water comes onto the boat deck through the drain hole that is located under the driver seat towards the back of the boat. This drain hole of course, is connected to the bilge pump and hose that drains water out.
On my 1996 Challenger, the cockpit drain hose doesn't connect to the bilge pump...it runs along the starboard stringer, then rises up slightly to it's own thru-hull fitting on the transom, just outboard of the coolant connector back there.
There is a rubber scupper valve just inside the transom mount ring. Mine has a big chunk missing out of it, and my boat would ship several gallons of water into the cockpit fairly often after I first purchased it (Aug 07). The rise on the drain hose is only a few inches, which exacerbates the situation.
I looked around other forums, and some folks seemed to like the Max flo ball-type replacement scupper valves, but others said they leaked just as bad as the OEM valve. A lot of people don't like the constant clacking noise that the ball generates.
I cut a piece of old inner tube and fashioned a hanging-flap style valve to cover the flat nylon transom ring. It's held by the two upper screws; I RTV'd a stainless fender washer onto the outside of the flap to give it some weigth and to maintain it's "flatness", so it can seal against the transom ring. It works well...in one day, I may see a quart come in, one time...many weekends, I never see any!
BTW, I also have a "strainer" of window screen inserted in the cockpit drain opening..it keeps leaves and miscellaneous bits out of the hose, and helps the flapper seal properly. I'd recommend doing that, regardless of the type scupper you settle on.

G'Day, this could help others with this problem. There is a rubber valve at the outlet of the deck water drain. If you put your finger in the hole you can feel the valve. this should be cleaned to make sure water can flow out.
I noticed recently that whenever I stop my boat on the water, some water comes onto the boat deck through the drain hole that is located under the driver seat towards the back of the boat. This drain hole of course, is connected to the bilge pump and hose that drains water out. It seems as if it working the opposite of what it should by sending a small amount of water(a gallon or so) back into the boat. Its never more than that so I'm not concerned with sinking or anything, and it drains back out as soon as I take off. Is there supposed to be a check valve or something on the bilge pump or hose to keep water from backing up that is damaged or missing. Anyone know what might be happening here?
