2018 Endurance 3556 water tank?

[RPM]

Hooked up to city water at the camp ground and yes I have a pressure regulator at the faucet. Came out the next morning and water is over flowing out of the fill cap for the fresh water tank. Some how water is crossing over inside some where. I don't have a clue where to start looking.

Check valve at the water pump. Disconnect the city water and try running the water pump. It might reset itself, otherwise, you will need to hunt it down.

I have the same unit. I had the same problem. I took it to the dealer and the service department could not reproduce it. (Figures) Before I took it into the dealer. I had to turn-off the city water and used the pump overnight. I didn’t want the tank over flowing all night.
I took the Endurance back to the park and hooked up the city water. Problem gone.
It seems if you cycle the pump it fixes itself. This problem may be due to the check valve hanging up. Not exactly sure, but this is what I read on similar posts.

I have a 2019. Look behind the false wall in the storage bay near the pump. There is a valve that shuts off the supply from the tank to the pump. Mine is just about center and about 12 inches off of the surface. It's a secondary incase the check valve on the pump fails or you can use it anytime you're hooked to city supply. Mine also has another directional prep incase I want to add something.

Thanks I'll take a look.
