Mount Pleasant, SC: what's different here
Mount Pleasant sits about 9 miles from Charleston via US-17, roughly a 15-minute drive. The town is served by the same state rules that apply across South Carolina: fire sprinkler backflow assemblies must be tested annually by a state-certified tester. Tester certification classes are held nearby at the North Charleston Convention Center on Coliseum Drive. A local pro can handle the test and paperwork for your property.
What does South Carolina require for a fire sprinkler backflow test?
South Carolina requires fire line sprinkler systems to be protected by a minimum approved double check valve assembly, tested after installation and before use. Annual testing is required for backflow prevention assemblies under state backflow rules. The test must be conducted in accordance with applicable NFPA standards.
Who can perform a fire sprinkler backflow test in Mount Pleasant?
Only a state-certified backflow prevention tester may do the work. Certification comes from a Department of Environmental Services-approved training seminar, with a proctored practical exam and a written exam, and must be renewed every 3 years. Ask the pro for proof of licence and insurance before the test.
When is a reduced pressure assembly required on a fire sprinkler line?
The South Carolina Department of Environmental Services requires a reduced pressure backflow prevention assembly when antifreeze, foaming agents, or an auxiliary water supply is tied into the fire line sprinkler system. Otherwise, a minimum approved double check valve assembly is required. The tester you are referred to can confirm which assembly your system has.
Do I need test results before a Certificate of Occupancy?
Some South Carolina cities require backflow devices on fire sprinkler systems to be tested and results submitted before a Certificate of Occupancy is issued. Test setup can also require municipal coordination, such as arranging a meter for the test. Check with your local building department for Mount Pleasant's specific requirements.
