another Auto-Vent

Here is another version of ballast tank vent for the 26X late model with vent under the vee berth. I couldn't find the Ace hardware type featured previously on this site but found a "flapper" valve in PVC plastic at a local farmer's supply that looked promising. I thought a ping-pong ball might be enough to raise the valve up, but it kept getting jammed in the chamber so I glued a cylindrical block of floatation foam to the bottom of the valve with WM marine silicone and then was able to pop in the ball to help lift the valve and obtain a tight seal. Used a cable tie to retain the ball from falling into the tank. Then I cut a flange from cutting board and glued it on with silicone as well. I chose the 2" version of valve to get maximum air flow, but a smaller valve would probably work just fine and be a better fit for a ping pong ball. Now I have to wait for spring to try it out!
