You can't replace just the check valve in a city water inlet because the inlet and check valve are a one-piece assembly.
Providing the check valve isn't really plugged up and blocking flow, one way to permanently fix this (rather than replace the inlet) is to add a new check valve to the interior side of the city water inlet. You'll need access to the rear of the inlet and usually can be reached. Go to a plumbing store and get an inline 1/2" brass check valve. Not sure if Lowes or HD will have them. City water inlets have a standard 1/2" pipe thread so you can just screw the new one in place. You may need a short nipple too. If the existing check valve seems to be plugged up, you can punch it out (I've done it before).
You might want to inspect the check valve at the FW pump too. Ours was leaking water back into the FW tank. We never use our FW tank and about a year after we bought the TT, I discovered the tank was filling up.
