Backflow assemblies must meet certain testing criteria. If the assembly fails the test, it must be repaired and retested. The technician completing the testing must complete a Backflow Assembly Test Report.
One copy of the report should be given to you, the assembly owner. One copy is retained by the technician. A third copy must be sent to your water purveyor. The water purveyor is required by the Utah Rules for Public Drinking Water Systems to maintain an inventory of all backflow prevention assemblies. They must also keep a record of all tests and repairs made on those assemblies.
