South Carolina Fire System Testing
In South Carolina, FLOW leads with two services. The first is underwater rover (ROV) inspection of fire protection water tanks, where a pilot flies the rover inside the tank while it stays full and in service. The second is fire hydrant flow testing, where FLOW runs the test, produces the report, and sends it to you. We cover hotels, resorts, coastal condominium towers, campuses, and industrial sites across the state, and we work from the NFPA 25 edition your AHJ has adopted. Coverage includes Charleston, Mount Pleasant & North Charleston, Columbia, Greenville, Spartanburg, and more. Local authority having jurisdiction (AHJ).
