Help water overflow nautilus 2.5

Has been working in the city water except recently where water has been back flowing out of the sanitize water connection which isn’t meant to happen

Good day
I’m getting confused when

1.I set my nautilus 2.5 to City water blue and green horizontal water comes out of the sanitize winterize connection
2. If I set it to dry camp it over flows my clean water holding tanks

I can send pictures thanks in advance

Has it been working? Or is this trailer/system new to you?

I would try turning both red and blue handles 180 degrees and see what happens. Wouldn't be the first time the manual was wrong.
It might be that the blue handle should be left as is and just turn the green one. I would try both ways and see what goes on.

Edit: On further thought, most water and gas handles are on when they are in line with the pipe and off when they are positioned 90 deg from the run of the pipe. I would turn the green handle so it points down (off) and leave the blue handle as it is (on) until the fresh water tank is full and then turn it down (off). In other words, I would fool around with the position of the handles until it works the way it should.

If you are wanting to connect long time to the hydrant, then both should be in the off position and the line from your water pump to the trailer pipes should be open. You would not have a hose connected to the top inlet - only the city water inlet (white hose at bottom right) At least this is the way it has worked in every trailer I have owned.:)

Above is the setting the manual suggests when I put it on this water comes out of the winterize sanitize inlet weird any ideas
