I replaced the city water inlet on my '19 TR 23DBS a couple of years ago when the check valve failed. Depending on where the plumbing is located inside it is a fairly simple process. In the 23DBS the inside access to the fixture is behind an access panel under the bathroom sink. On the 24RKS I think the city water inlet comes in under the kitchen sink. As Skip426 recommends - I would change the cone washer while you have it apart.
Here are a few pictures from my replacement to give you an idea:
