I'On: what's different here
I'On is a master-planned residential neighborhood located in Mount Pleasant, east of downtown Charleston. Its streets and canals feature a New Urbanist design. Homes in the area were largely built in the late 1990s and early 2000s. Charleston's humid subtropical climate brings frequent heavy rain and high humidity to the area.
South Carolina Backflow Testing Regulations in I'On
South Carolina DES requires all backflow testing to be done by a state-certified backflow prevention tester. This certification is valid for three years and requires passing both a written and hands-on wet-lab exam. The state recognizes four types of certified testers: General, Limited, Inspector, and Manufacturer’s Agent.
Why Backflow Testing is Crucial for I'On Properties
The humid subtropical climate of Charleston brings frequent heavy rain and high humidity. These conditions can increase corrosion and moisture exposure around outdoor plumbing and irrigation backflow assemblies. Furthermore, the low-lying coastal setting poses risks from stormwater and tidal flooding.
Understanding Backflow Testing Costs
Costs vary based on the system size, with residential testing listed at $85 and commercial testing at $125 for common sizes. The state application for certification processing carries a $150 fee. All reports must be filed with the Charleston Water System.
The Certification Process for Backflow Testing
South Carolina DES mandates that backflow prevention assemblies must be tested after installation and before use. Annual testing is required thereafter, and the gauge used for certification must be accurate within 2% of full scale or +/- 0.3 psi differential.
What to do next
- Verify the pro has a current state-certified backflow prevention tester certification card.
- Confirm the gauge used for certification is accurate within 2% of full scale or +/- 0.3 psi differential.
- Ask for a quote detailing the specific type of backflow testing required for your system size.
- Ensure the final report is filed with the Charleston Water System through its third-party reporting process.
