Tester Certification

About the course

This intense five-day course offers instruction on acceptable test procedures for testing backflow prevention assemblies. Certification enables the tester to test initial installations as well as perform the annual testing of assemblies as required in the Louisiana Administrative Code. The 40 hour course consists of classroom instruction and hands on practice Monday through Thursday with certification exams given on Friday. Students must pass both written and hands on exam in order to receive certification as an approved Backflow Preventer Tester.
