How long is a manufacturer’s certification for installation valid and how often does one need to recertify?

BlazeMaster CPVC manufacturers do not certify. We do, however, offer a comprehensive,
world-recognized training program that is unmatched in the industry. Our mechanical and
technical excellence is demonstrated through an in-depth presentation, hands-on exercises and
a final examination. Each attendee receives a training card and certificate to show inspectors
on-site to demonstrate their training. We recommend that installers/designers take the course
every two years to cmpensate for industry and product changes and enhancements.
