What does backflow preventer winterization involve in Charleston?
Winterization in South Carolina is described as a blowout service done before the first hard freeze to remove water from pipes and components and prevent freeze damage. For a backflow assembly, the goal is protecting the device from cold. Ask the pro what their winterization includes for your specific assembly.
Who can test or repair a backflow preventer in South Carolina?
South Carolina law requires all backflow prevention assembly testing to be done by a state-certified tester holding an up-to-date certification card issued by the Department. Repairs must also be made by a DES-certified backflow prevention assembly tester. Ask the pro for proof of licence and insurance.
How often must backflow assemblies be tested in South Carolina?
South Carolina requires backflow assemblies to be tested at least once annually, and again after installation or repair. The water system or purveyor tracks assemblies and enforces installation and testing requirements. A winterization visit is a good time to confirm your test is current.
How do testers get certified in South Carolina?
Tester certification is earned after a proctored practical exam and a written exam through a DES-approved training seminar. Certification must be renewed every 3 years, and the application lists a $150.00 processing fee per certification. A three-day state-sponsored workshop option costs $250.00 per person.
