Introduction: Winterizing Your RV
I hate the taste of the pink RV antifreeze and so have tried to reduce my exposure to it over the years. This is a safe and easy way to fully protect your camper and RV for winter without having to dump the chemicals into your freshwater holding tank. A simple modification will allow you to pump and protect the system and keep that holding tank clean and clear.
My method does not use compressed air but you could for an additional (but unnecessary) level of protection.
