The winterizing inlet bypasses the fresh tank as well. This assures that the anti freeze goes into the water lines only and does not pump excess anti freeze into the tank.
The connection is on the suction side of the pump and the pump output does not go to the fresh water tank.
I add bleach, fill the water tank, then purge the water lines so that they get sanitized.
If you sanitize the hot water then drain it and the fresh water tank, refill and purge everything with fresh water.
Alternate: We use a reasonable amount of treated city/utility water in our travels and hence have very rarely sanitized.
