It was because the water pump backflow check valve failed and the city water pressure filled the fresh water tank and caused the water to flood. I rebuilt the pump twice and the check valve still would not stop the tank from filling. I installed a PEX loop with a Flair-it valve between the city water and the onboard water pump. No more flooding. Maybe that’s your problem? Lineman
