The Backflow Tester Refresher Training takes place the same week on Thursday and Friday, a 16 hour "refresher" course. This course allows experienced certified testers to refresh their knowledge and skills, before taking the re-certification test. Any "refreshing" attendee who wishes to attend all 40 hours must attend the Monday Session with the new students. THE CERTIFICATION EXAM IS A SEPARATE FUNCTION OFFERED AFTER THE TRAINING. ATTENDEES WHO WANT A TESTER CERTIFICATION WILL HAVE TO REGISTER WITH ABPA BY GOING TO: https://www.abpa.org/event
