Summerville, SC: what's different here
Summerville sits in Dorchester County, South Carolina. Its housing stock includes many postwar suburban homes and newer subdivisions, and backflow devices are commonly installed on irrigation and fire-sprinkler systems in both residential and commercial properties. Summerville is about 25 miles and roughly 29 minutes by car from Charleston via the main highway.
Who is allowed to perform a fire sprinkler backflow test in Summerville?
South Carolina law says fire sprinkler backflow testing must be performed by a state-certified backflow prevention tester. The tester must hold a current Tester Certification Certificate, and the test must follow applicable NFPA standards. Only certified testers can perform the work.
Does a repair to a fire sprinkler backflow assembly need a different tester?
Yes, South Carolina law requires any repair to the backflow prevention assembly to be made by a DES-certified backflow prevention assembly tester. A standard test does not automatically cover repairs. Ask the pro whether a repair is needed before work begins.
How long does a fire sprinkler backflow test take?
Most backflow tests take less than 30 minutes, depending on the device size and type. Another utility guide notes that water is off for only a few of those minutes. Ask the pro for a time estimate when you request a quote.
How do I verify a tester's certification in South Carolina?
The SC DES defines a certified tester as a person holding an up-to-date backflow prevention assembly tester certification card issued by the Department. South Carolina backflow tester certification is valid for three years and must be renewed. Ask to see the card before the test starts.
What to do next
- Ask the pro to show a current state backflow tester certification card before the test begins.
- Confirm the test will follow applicable NFPA standards, as South Carolina law requires.
- Ask for a written quote that lists whether a repair is included or would be billed separately, since repairs must be made by a DES-certified tester.
- Ask the pro for proof of licence and insurance before you agree to the work.
- Call (843) 286-4721 or email [email protected] for a free quote from a licensed, insured local backflow tester.
