DLLR, WSSC, and DC Approvals

For Maryland State, Our 32 and 8 hour courses are approved by DLLR through registration with the plumbing board as a course provider, this approval is listed here. This course is mostly taken as a pre-requisite for a plumbing license application, and during the course it is discussed how to file the application and what to expect on the state test with PSI (candidate info bulletin can be found here )

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 or VA, the instructor will be on the list and thus compliant with WSSC. Their instructor's list is posted here. The 32-hour and 8-hour courses for WSSC area also taken as a pre-requisitie for a license application or renewal.

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 (the water utility NOT the board of industrial trades). We have submitted our information to DC Water, but they do not have a list of approved course providers they evaluate the provider and course on a case by case basis.
