Help water overflow nautilus 2.5

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?
