White hose protruding from under the

One quick question on winterizing our 2012 FB Flying Cloud.



There is a small hose protruding from under the AS by the back access door. I believe I had closed the handle on the pipe on the inside of the access door and when I was adding antifreeze I notice the antifreeze coming out of it. Is that suppose to happen? It did not when I turnt the small the handle the other way on the pipe that is inside the access door.



Also do you leave the fresh water drain open or closed for the winter?



Thanks

John
