over flowing fresh water tank ??

Well here we are in a beautiful site over looking the ocean in Maine.
Loving life and enjoying our '09 Fuzion 403 for the first time this summer.

When... My wife shows me the main freshwater tank is overflowing from the fill port. Hmm. This can't be right< I only put 30 or so gallons in at home because we would be hooked to site water for our stay here.

I am hooked to site water...have been for three days.
I did not have a pressure regulator on.....until just now
Is there anyway water can get into the main fresh water holding tank
without going thru the actual filler port?

Maybe your diverter valve is not switched all the way to city water, or you have a bad check valve and water is flowing back through your pump into the tank.

Don't believe everything you think.

I have a diverter valve?
That may be a very good thing to add.
The check valve for the pump makes sense. That will get looked at today.
Thank you
