"physics, gravity, and law enforcement are the only things that prevent me from operating at my full potential" - not sure, but i like the quote

you know you are not an engineer if you have to remind yourself "left loosy righty tighty"

Nifty. It's like your old one, but better. That's always good, progress is what leads to new discoveries.

Theres a post here to use a coupling instead of a end cap. Its for 2" but you can use the same idea here to mod it for 4" if you are still having problems.

Just courios but what is the (toilet flange?) compacter thing do for you?
