Modern RVs with city water hookup
The city inlet is after the pump
Between the pump and the rest of the water system
The city inlet does not fill the fresh water tank (it simply pressurizes the water lines) unless there is a bypass valve to open that goes around the pump
The FW tank is Never Ever pressurized by the city water system
Most RVs have a separate water fill inlet going to the FW tank not using the city hookup and a bypass valve and the RV water lines to back fill the FW
