Winterizing a 2016 Windjammer 3025W
I realize this subject has been probably been beat to death, but I've read many, many, many threads and just have not been able to find the answer to my question.
I purchased the 2016 Windjammer 3025W yesterday. During my walk through when discussing the outside panel that contains an inlet and a switch for winterizing, I asked the tech conducting the walk through that if I switch the blue lever, marked "winterize" if this switch actually was the water heater by-pass? He said, "yes, no, I will show you that later". Excited as I was to take possession of this camper, I never followed up on this with him and it never came up.
The water heater in this unit is located between two slides and appears to be behind a hinged panel in the bedroom, below the closet, that does not open. Pretty sure I will have to remove the hinge to access the WH.
My question: Even though I have the outside panel and the switch that states it is used for winterizing, do I still need to access the WH and locate the bypass valves? It just does not make sense they would put this behind a panel that does not open. I really need to Winterize right away, so if anyone can help, please do. Thank you.
