I bought my 2017 38REFS last November and I am getting ready to de-winterize it. The dealer winterized it and mentioned that they would be happy to de-winterize it for me. I think I can handle the job myself. I do have a question about the residential refrigerator. It have an ice maker and water in the door. I can't tell if the water line for the reefer is hooked up or not. Is there a valve somewhere that I have to turn on? I don't think there is any pink AF in the system. I currently have the icemaker off and of course because it is winterized there is no water in the system. What is the "usual" procedure when the dealer winterizes residential refrigerators? Do they shut of the water before the pump the pink stuff through?
