Do I need a permit for plumbing fixture or repiping in Sumter County (Unincorporated)?
Yes. In South Carolina, plumbing fixture or repiping generally requires a permit, and Sumter County (Unincorporated) is no exception.
A whole-house repipe requires a plumbing permit and a pressure test while the piping is still exposed. Do not close up walls before that rough inspection passes. Approved piping materials and any backflow protection are checked at inspection, so confirm the accepted materials with the building department before buying.
