Black Tank Flush System.
Anti=siphon vacuum breaker device is mounted at least 2' above the top of waste tank
Waste tank would need to be FULL and PRESSURIZED to florce flow from waste tank back thru Spray Nozzle, UP 2' then down into hose which would need to be connecged to a water supply system that has NO pressure in order to 'contaminate' the water supply system
Possible........sure
Probable............HIGHLY UNLIKELY
There is NOT a 'law' making it illegal to remove the device
RIVA requires it for RV MFG to use RIVA Seal on there products
A simple backflow preventer on the supply hose will do the same
ATLEE......
Common Sense is NOT lost :B
In addition any campground whose water supply meets code is going to have a backflow preventer on the connection itself like the one shown in your post. You may find them missing in some private parks, but I have yet to see a fed, state, or municipal managed campground without them.
I present to you the backflow police, a division of the weight police.
