The hands-on event will be dedicated to reviewing the field test procedures for backflow prevention assemblies. A limited number of participants will have an opportunity to review the field test procedures and diagnostic scenarios found in the Manual of Cross-Connection Control, Tenth Edition with Foundation staff. Plus, the Los Angeles County field test procedures will be also demonstrated for attendees who may be recertifying with the county. The session will provide attendees with access to assemblies, as Foundation staff review the procedures step-by-step with additional diagnostic scenarios. The session is a great opportunity for attendees who need to review the procedures and diagnostics before a recertification exam.
