What should I do this week to schedule bulk testing?
Make a list of all ten units with each device's location and size. Send that list to a local pro through CHS Backflow and ask for a single appointment window. Scheduling several units together makes it easier for one tester to cover the work in one visit.
What should I check when hiring or switching testers?
South Carolina requires all backflow testing to be done by a state certified backflow prevention tester. Ask the pro for proof of certification and proof of licence and insurance before booking. Certifications are issued and renewed through SCDES, and testers renew every three years.
What types of certified testers are there?
South Carolina DES identifies four certified tester types: General Tester, Limited Tester, Inspector Tester, and Manufacturer's Agent. Confirm which type covers the assemblies on your properties. Ask your pro to name the type on their quote.
What devices must be tested?
South Carolina regulation says no person may install or maintain a cross connection unless an approved backflow prevention device or assembly is installed between the public water system and the contamination source. Testing covers these installed devices. Ask the pro to list each assembly they will test.
What to do next
- Inventory every backflow assembly across all ten units, noting make, size and location.
- Verify the tester holds a current SCDES backflow tester certification before booking.
- Ask the quote to include a per-unit testing line and a single combined schedule.
- Request a written test report for each unit and confirm the paperwork submission process.
- Call (843) 286-4721 or email [email protected] for a free quote from a licensed, insured local backflow tester.
