I have a perplexing situation I am confused about. I am on a trip and have filled my Fresh Water tank 2/3 full. At the first campground on my trip I connected to the water connection at the park to my labeled City Connection to supply water. The next morning when I was disconnecting to leave I noticed that my RV spot had gotten wet. When I looked under my RV water was coming out of my Fresh Tank Overflow. I went inside and looked at my water tank and it was full. We used the fresh water tank to bring the level down. It happened again at the next site and at the one I am staying at.
I have a 2018 Winnebago Minnie Winnie 31G. I have looked at the 3D drawings for plumbing at the city water connection and it doesn’t show a direct connection to the fresh tank. The only thing I can figure is that the water is back flowing through the pump into the water tank.

Has anyone else experienced this issue or something similar? If so how did you correct it.
Thanks,
