Backflow Recertification

August 19, 2017 @ 7:00 am - 6:00 pm

Every three (3) years a Cross Connection/Backflow Tester must recertify or lose their certification as a Backflow/Cross Connection Tester. The Maryland State Board of Plumbing, WSSC, Baltimore County, District of Columbia, require the successful completion of an approved 8-Hour Backflow Training Recertification Course to keep this certification and license current. The recertification course will focus on the following:

  • Updates and new developments in Cross Connection Control
  • Review of causes and principles of the backflow and backflow prevention
  • Review of proper backflow prevention assembly application and operation
  • Review of accepted field test procedures for all backflow prevention assemblies
  • Review of differential gauge use and recommendation gauges
  • Review of PVB, DCVA, and RP test procedures and wet lab practice

A passing grade on the final written examination and a satisfactory completion of the ¬Ëœhands-on’ performance will result in certification. Certification is good for three (3) years.

If you fail the course and are required to re-test you will be notified by the office
