Yes that does help, and I have found and figured out how to use the installed bypass. I opened the panel under the bathroom sink to get to the pump, took our the filter and put the cover back on. I can get it to pump out of the antifreeze bottle so I am ok now with that.
The only issue I am having now is trying to drain the 5-6 gallons of antifreeze from my fresh water tank. Under the trailer is a 3 inch hose with cap. When that cap is removed all that came out was about a tablespoon of antifreeze and not the 5-6 gallons. Not sure how to drain it, the owners manual isn't that good in telling me where things are. I have found 3 (what looks like drains) but don't know. One is the 3 inch blue house directly under the fresh water tank like described above. The other two are a red and blue (I would think hot and cold?) at the rear of the trailer. I did unscrew those two and again only a tablespoon came out.
On my hot water tank, there are 3 valves. One for the hot one for the cold and on inbetween. I have the hot and cold off and the one in the middle on. I am sure the loop is correct because I do get antifreeze to the faucets. I am not going to worry about the fresh water tank this year since the antifreeze wont hurt anything, I just need to drain it somehow....
