city water overflowing into fresh water tank

kteichert

It looks like when I turn on the city water instead of the water shutting down when no water is being called for it is running into the fresh water tank then overflowing out the overflow vent.  How do I fix that?  It is a 2018 T@b 400.

The issue is the water pump check valve.  See here;

Thanks Sharon- this makes sense - we were going to replace the pump anyway so I have a replacement ready - hopefully that will do the trick

@kteichert - there is also a check valve at the city water port.  Please email nuCamp at Help@nucamprv.com to confirm which check valve is the culprit!
