Is it normal for the expandable plug to pop out of the return fitting?Ea. year when the ice starts to melt and I have a island of ice in the center that slowly floats around on windy days it seems to pop the plug out " froze around the wing nut" and I lose a little water that I was hoping to let mother nature re-fill.I tightened as tight as possible by hand and don't really want to over kill it in avoiding some damage.It is a cone shape so I assume not a whole lot of it actually grips when expanded.

I wonder if you were to fashion a cover for it. Use something like a plastic cereal bowl and attach it with cord through the center / bottom to the wing nut. Something rounded like that so the icebergs are deflected.

thanks for the tips, will try a different plug first.I know the one I have now has a long stem to tighten and does give the ice some sideways leverage .

Now I see why some don't have the pop out problem, I have to use the rubber cone type, so not much grip when inserted.this does not have threads since its smooth inner wall.
