I am confused as to what you would be watching when cleaning the Black tank? The Black tank flush is a device inside the tank, essentially an octopus which waves it's arms and sprays the interior surface? I can't imagine you open the toilet valve while that is going on as it would likely spray out at you???
As others have said, for obvious sanitary reasons, there is no link between your fresh water system and the black water tank. The only two access points are the toilet and the black tank flush.
I am guessing by Tank Sanitize you mean the settings on the two dials on your rig. I think that is positions 1 and 4. That is not for sanitizing your black tank. That is for sanitizing your fresh water system.
The black tank flush is achieved by connecting the hose directly to the water intake designated for that purpose. In your case I believe it is the connection below the "City Water Connection".
I would bet a significant sum that you have hooked your hose up the "Black Tank Flush" instead of the "City Water Connection"
