DLLR, WSSC, and DC Approvals

For Maryland State, Our 32 and 8 hour courses are approved by the Department of Labor Licensing and Regulation - Plumbing Board. This course is mostly taken as a pre-requisite for a plumbing license application or required to keep a license registered with the state or a county.

For WSSC, the program has to be approved by DLLR and the instructor should be listed on the WSSC instructors list. If taking a course with us in Maryland, the instructor will be on the list, otherwise it may not be.

For Washington DC, the backflow course is not required for the plumbing license, but is required in order to test backflow preventers. Once you take our course and receive the diploma, you need to submit this with some other information directly to DC Water.

Which Backflow Preventer Testing Procedures Should I Use?

There are a bunch of options when it comes to testing backflow preventers as far as which procedures to use. We have found that the ASSE 5000 Single Hose Procedures are most efficient if you can use them, and have fewer requirements as far as equipment, connector tees, and number of hoses and adapters needed.

On our YouTube channel, we created a series of videos where we test the four types of preventers using these procedures if you're not familiar with them:

Reduced Pressure Principle (RPZ) - ASSE 5000 Single Hose Procedures

Double Check Valve Assembly (DCV) - ASSE 5000 Single Hose Procedures

Pressure Vacuum Breaker (PVB) - ASSE 5000 Single Hose Procedures

Spill Resistant Vacuum Breaker (SVB) - ASSE 5000 Single Hose Procedures
