    Fresh Water Tank Won't Fill

    We just purchased a 2017 RLS 5th wheel with the nautilus system. First camping trip with it, we can connect direct to city water hook up and water comes out, but we can't keep it connected due to temp right now. We have tried to fill the fresh tank but the water seems to be going into the hot water tank We've double/triple checked the valves are in the correct position. Any suggestions? our dealer had nothing to offer, and it was winterized when we took possession.

    Kim - See this thread for a wealth of knowledge on how the Nautilus system works, including diagrams made by a member of this forum.

    We currently have a similar situation with a 2014 Reflection 337, Kantleak panel. It has had 2 or 3 replacement panels, and 2 valve inserts into the current panel. We full timed for over 3 years, and had it in storage for the last 8 months. Before we left Texas, I filled the fresh tank, and just did the same 3 days ago here in Colorado. Today I needed to fill again, and it would not accept water. I put in an insert kit from Anderson, same problem. I finally turned the valve to 45 degrees to the left of top dead center, and was able to slowly fill the fresh water tank. Any ideas will be appreciated!

    Hi Steve - If you have changed the valve core that many times, I wonder if all the O rings are accounted for? Some of the failure modes are shredding the O rings and/or blowing them loose. I would be inclined to pull the Kantleak valve body and make sure there are no old O rings jammed in there anywhere.
