Permit required

Yes. In South Carolina, water heater replacement generally requires a permit, and Rock Hill is no exception.

A straight water heater replacement still requires a permit in South Carolina jurisdictions. The inspector checks the temperature and pressure relief valve, discharge piping, drain pan and any expansion tank.
