Winterizing Windsport 27K
I am about to winterize our Windsport 27K and have a question specifically about the water heater. It is in an enclosure under the frame. I see only access through the outside water heater door. I don't know if it has by-pass valves, and if so where they are located and how to get to them? Also, if anyone has a step-by-step procedure for winterizing the water system, I would appreciate having it. In the past on other RVs, I normally drained the system, blew air through the lines, and pumped RV antifreeze through all lines.
