I have never worried about winterizing the black tank (or grey tank). I just empty them and run enough water through them to have them clean, but I do that every time.

I am talking about the flush system for the black tank. The one you hook up a hose to and flush the tank. I think the blow out of this line might be the best idea. Thanks for the input.
