This problem is specific to my 1999.

FWIW, Trying to fill a water heater will take 6 gallons of RV antifreeze, at 5 bucks a gallon, that is going to be expensive, and that is ASSUMING you figure out how to have the Electric pump suck the antifreeze directly from your 1gallon jugs, if not last year I had to dump 3 gallons into the fresh water tank, just to get enough volume in there to run through the cold lines and fawcets. so it could easily be 7 or 8 gallons of RV antifreeze... Walmart might be cheaper, used $5 because that was what my local store sold it for yesterday, to me.
if you can easily get to the back of the water heater, you could install your own bypass reall easily. Mine I did the 2 valve system, worst part was getting to the water heater's water connections. I am making a door for this to make it much easier ASAP...
