Backflow preventers keep dirty water from flowing backward into your clean drinking water — and in many cases they're required to be tested every year. Saltmarsh Plumbing tests, repairs, and installs backflow prevention assemblies for homes and businesses, and handles the paperwork so you stay compliant.

Whether you have an irrigation system, a pool, a commercial property, or you've received a notice that your device is due for testing, we serve customers across Bluffton, Hilton Head Island, Okatie, and the SC Lowcountry. Locally owned and family-run, we make it simple and get it done right.

Due for a backflow test or need a repair? Call Saltmarsh Plumbing at (843) 310-9005.
