A second winterizing question lol
First of all my 22fe was soooo easy to winterize. Pop the panel off below the reach thru closet and there is the water pump. There is an inlet set up for drawing antifreeze into the system. the great thing is there is also a valve so no antifreeze goes in the fresh water tank. So here is my question. I have seen discussions on putting antifreeze into the hot water heater. Most err on the side of not doing it. Can anyone explain why? Is it the glycol?
