This class is for people who want to renew their American Society of Sanitary Engineers tester certification. You must document five years of plumbing or drinking water industry experience on the application that we will send to you after you register for the class. Participants must pass an online exam and perform a hands-on exam on a RPZ, DC, PVB, and SRVB, where one of the assemblies will fail and the failure must be properly diagnosed to be recertified. The cost includes the ASSE recertification fee. Note: Students must submit a class application by October 3.
