Always fun when someone on a post revives something posted that's really old. I missed this before, but your intake of the little angled brackets to twist is looking perfect for me. I've gone with caps and ball valve, but left that to be able to get equal intake all around. Been playing with magnets and that's fine as long as you just have 1/2 holes. I have larger ones and I was thinking of trying to weld them shut and start over, but your idea may save me from that.
