Fresh water tank
I have a '15 Columbus which the fresh water tank was never used. When I winterize with air and drain , I always have a little bit of water come out of fresh water drain. I was going to sanitize my tan...

There should be a drain for the fresh water tank also...otherwise, you have to dilute with large amounts of antifreeze to protect the tank.
Blowing air up the low point drains shouldn't have any impact on the fresh water tank as there should be a one way check valve at the pump that would stop any flow back into the tank.
So it's not clear what issue you actually have.
