I just remembered the name of the pond owner; David Reed of Fairfield, Texas. Nice guy.
I expect 4 inch pipe would work. I doubt that you would need any weight. It ought to drop down due to its weight. A plunger might force it out through the drain holes. I would also cap off the top. Its not much fun to dig a dead squirrel out of the pipe. As a matter of fact, I'm not sure what would keep squirrels and coons from chewing through the pipe to get at the feed.
Sunil, it didn't take all of the 12 steps to learn the error of my ways. To my little girls it was like eating their kitty cats.
