What is an rpz valve test in Charleston?
RPZ testing verifies that a reduced pressure backflow preventer is functioning correctly. This assembly is critical for protecting the water supply from contamination. Most water authorities in South Carolina require annual testing and reporting for these assemblies.
Local Training and Certification for RPZ Testing
A Charleston-area certification class for backflow testers was scheduled at the North Charleston Convention Center. South Carolina awards tester certification only after a proctored practical exam and a written exam are successfully completed. The certification processing fee is $150.00 per certification.
State Requirements for Backflow Testing in Charleston
South Carolina requires all backflow testing to be performed by a state certified backflow prevention tester. The South Carolina DES defines a certified tester as a person holding an up-to-date backflow prevention assembly tester certification card. This ensures the integrity of your water system.
