You should only need the Valterra Check Valve for RV Fresh Water Systems # P23415LFVP at the cold inlet of your water heater. Typically you will have a total of three fresh water check valves; one at the cold inlet to the water heater, one at the city water inlet and one located at the outlet of the water pump.
