Years past I would drain water tank. With valve open I would then connect air compressor to shore water inlet and blow out all faucets. When done I close heater drain valve.
Then i would add antifreeze thru strainer for engines. I never had antifreeze fill heater back up that I’m aware of.
Based on what you see do you see any issue with what I’m doing? And if I bypass cold and hot water lines which cold line based on what you see?
