Help water overflow nautilus 2.5

[tourusa]

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

For sure always appreciate everyone’s time on this and it was a call from nautilus that gave me this and the 10$ fix is the camco valve which will fit inline instead of replacing the old water pump. Lots on you tube which I’ve been watching also

Thanks for coming back to let us know the final outcome. Most of the time we never hear how things turned out.

Backflow preventor in the pump failed due to hard water I’ll be purchasing

camco 23303 inline preventor and will run the pump for 20min on dry camp see if it unsticks the Backflow preventor

Thanks, not sure of how to replace the valves and part numbers I’ve pinged the manufacturer to get there take on this back pressure pushing water out in the reverse

Hmmm, the Sanitize/Winterize goes to the pump, so maybe you have a valve/check valve leaking past the pump on out the Sanitize/Winterize. Also I have heard of these Green/Blue rotary valves having damaged O-rings and water leaking past them. Perhaps the Green valve O-ring is allowing water back out to the Sanitize/Winterize.

I haven’t had a hose in the winterize connection only the black tank flush, the water is somehow coming out of the white winterize connection when I select city water

If I move them to dry camp below then my water tank over flows

You got me beat! 🙂

If you are connected to a city water supply with your white hose, there is no need to connect another hose to the fresh water inlet for filling the tank. That would only be connect for a short time while you are filling the tank.

Could it be possible your problems started when you connected the black hose recently?

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

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
