When I am camping and the temp goes below freezing I will always remove the city water hose connection. This is the first thing that freezes up for me if left connected.
My pump is only used when I am using water from the fresh water tank. When connected to the city water the pump is not required and is turned off.
This is a very simplified pictorial on how the typical RV Water system is configured. Might give you some information figuring out what is happening at your specific location..
