Who is qualified to perform a boiler backflow preventer test in Charleston?
All backflow prevention assembly testing in South Carolina must be conducted by a state-certified backflow prevention tester. This certification is issued by the Department of Health and Environmental Control (DHEC). Testers must pass both a written and a proctored practical exam to earn this designation.
Why is regular backflow testing important in Charleston?
Charleston has a humid subtropical climate with high annual precipitation and humidity. These moisture-heavy conditions make annual backflow testing important for maintaining system integrity. Backflow testing is commonly scheduled as an annual inspection for both residential and commercial systems.
What are the requirements for a certified backflow tester?
South Carolina requires that a tester’s differential gauge be accurate to within 2% of full gauge scale or plus/minus 0.3 psi differential. Certification for a backflow tester expires every three years and requires re-certification to remain valid.
What to do next
- Verify that the local pro possesses an up-to-date backflow prevention assembly tester certification card issued by the Department.
- Ask for proof of licence and insurance before scheduling the boiler backflow preventer test.
- Confirm the specific device type when requesting a quote, as costs vary based on the equipment being tested.
- Ensure the tester verifies the differential gauge accuracy is within the required 2% or plus/minus 0.3 psi.
