All installations of state approved backflow prevention assemblies must be located at the connection to the water meter on the customer's side of the property line, and prior to any connection downstream (Premise Isolation). The installation must be approved and inspected by Covington Water District. Prior to inspection by the District, a Washington State Certified Backflow Assembly Tester must test the backflow assembly for proper operation, complete a test and maintenance report signed by the backflow assembly tester, and submit a copy to the District. Thereafter, annual testing and maintenance reports must be completed and submitted to the District.
