If I read your post correctly,
1- You have the by/pass valve open that switches the water pump suction side from its normal operation of taking water from your fresh water tank, and now suction anti-freeze thru a hose stuck in a bottle of Anti-Freeze
2 - You have the second by/pass valve close to stop anti/freeze from entering the cold water inlet side of your water heater, and when in that position allows anti/freeze to enter the hot water piping of your R/V
3 - What most people do not know, is what the heck is stopping the anti/freeze from entering the hot water outlet in your water heater
That because to save money - instead of putting a third valve to stop the anti/freeze from entering the hot water outlet of your water heater--------There is a check valve and I am guessing your check valve is junk and letting anti/freeze into the water heater via the hot water outlet pipe.
FYI - Looking at that outlet nipple that threaded into the hot water side of your water heater - it looks just like a 2" or so nipple - NOPE, there is a check valve inside that puppy.
Lastly go with a brass check valve instead of the plastic one.
