Backflow Prevention (Installation and Certification)

Importance of testing backflow prevention devices annually

Mechanical backflow prevention devices have internal seals, springs and moving parts that can become dirty and wear out. They must be tested annually with properly calibrated equipment to ensure they are working properly.

Testing must be performed:

  • by a licensed backflow tester
  • using properly calibrated test equipment
  • at the time the backflow prevention device is installed, repaired, replaced or relocated, and annually thereafter
