Winterizing and fresh water tank
Our rv has a port near water pump for winterizing our rv with antifreeze and I know the procedure for doing that. My question is about protecting the fresh water tank from freezing. Even if I open the drain valves on my fresh water tank there is always about an inch of water left. So that leaves me with some water in the freshwater tank and the water line to the pump. It does not seem as though this line would be removable the way it is attached. Any suggestions on protecting this from freezing. It seems as though adding antifreeze here it would be diluted by the remaining water.
