Maryland Backflow Tester Certification Courses
COURSES ARE PERMANENTLY PAUSED
Unless something changes, we will likely not be offering backflow courses in Maryland at any point in the future, but it was cool to be a part of the cabal both with my father and on my own for many years. At some point we hope to get whatever licenses and a fair review but likely have to do a lot more networking with code officials and state reps / senators to maybe change the COMAR.
Which Backflow Preventer Testing Procedures Should I Use?
We have found the USC-10th Edition testing procedures to be the most efficient. On our YouTube Channel, we created a series of videos where we test the four types of preventers using these procedures:
Testing the Reduced Pressure Principle ( RP ) - By the Book
Testing the Double Check Valve Assembly ( DCV ) - By the Book
Testing the Pressure Vacuum Breaker ( PVB ) Assembly - By the Book
Pressure Vacuum Breaker (PVB) Possible Failures & Diagnostics
Double Check Valve ( DCV ) Possible Failures & Diagnostics
Reduced Pressure Backflow ( RP ) Possible Failures & Diagnostics
