It sounds like your bulkhead is too large by maybe 1/4". It should fit nice and snug inside the bulkhead. You will get some water that still leaks, but it should be minimal. I refuse to glue mine, but I have never had any issues as far as excessive draining or floating!
Hmm not sure. I may just try making I snug with Teflon and see how it goes. I wouldn't say it's excessive at all, but if I lost power for a day I can estimate the overflow box would be drained. But I guess I'd have bigger problems at that point anyway.
