After running antifreeze thru the outside shower, I connect the outside shower hose to the black tank flush connection and use it run antifreeze thru the black tank flush. Just takes a minute or so.

To winterize the washer, I turn the temp setting to cold and run the washer until I see pink stuff thru the window. Then I run spin until all that liquid drains. Then I turn the temp to hot and run again until I see pink stuff. Again I run spin until it drains. That winterizes the lines and puts pink stuff in the drain P trap.

As far as how to winterize the washer lines if you have no washer, I defer to others who do that each year.
