Certification
CEU / Backflow certification.
CMPA is a recognized provider of CEU (Continuing Education Units) & Backflow tester training, certification, and annual re-certification — trusted by water authorities across Greater Cincinnati.
What is CEU / Backflow?
Protecting Cincinnati's drinking water, one test at a time.
Backflow prevention assemblies protect potable water systems from contamination. Backflow tester certification verifies that a plumber is qualified to install, test, and maintain those assemblies in compliance with state and local water authority requirements.
