Do I need a permit for water heater replacement in Sumter County (Unincorporated)?
Yes. In South Carolina, water heater replacement generally requires a permit, and Sumter County (Unincorporated) is no exception.

The inspector checks the temperature and pressure relief valve, discharge piping, drain pan and any expansion tank. Switching from a tank to a tankless or changing the fuel or venting adds gas, electrical or mechanical requirements. Confirm scope before buying the unit.

Its online permit portal is https://sumter.govpossible.com. This is a joint city-county department: it covers the City of Sumter, the unincorporated county and the towns of Mayesville and Pinewood, so the same counter handles addresses on either side of the city limits.
