Thank you for choosing us in the past and hopefully the future.
Our courses in Maryland are paused. We are looking for a TREEO or ASSE Instructor that could teach in the state of Maryland for us, if you are or know someone who may be interested please contact us at 917-887-5613 or firstname.lastname@example.org - it is a relatively simple process to get instructor certified and would set up a dedicated program to meet TREEO or ASSE's requirements which include exclusion of one hose RP testing and 2 valve test kits, which has become super popular in many other states thus creating the issue.
If you are looking for a backflow course in the mean time, I would check out the list of approved schools with DLLR there should be one in your area.
My apologies on the inconvenience.
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.
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
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:
