On my 5er you can't do just one part of the system. You could have valves installed to shut off that part. Then you would have to leave the valves open, then blow out the lines, close the valves when no water comes out, and then you could turn water on to rest of trailer.
Our trailer has a vent that goes into the outside kitchen from the bunkhouse room, that helps heat and cool the outside kitchen some with the door shut.
