(a) Backflow preventer assemblies shall be tested and inspected at the time of initial installation or first inspection and at least every twelve (12) months thereafter.
(b) Periodic testing shall be performed by a tester certified by the West Virginia Bureau for Public Health. This testing will be done at the Owner's expense.
(c) Any backflow preventer assembly which fails during a periodic test shall be repaired or replaced. When repairs are necessary, upon completion of the repair, the assembly will be retested at Owners expense to insure correct operation. High hazard situations will not be allowed to continue unprotected if the backflow preventer assembly fails the periodic test and cannot be repaired immediately. In other situations, a compliance date of not more than thirty (30) days after the test date may be established. The Owner is responsible for the costs of all testing, repair service, replacement parts or a replacement assembly. Parallel installation of two (2) assemblies is an effective means of the Owner ensuring uninterrupted water service during the testing or repair of the assemblies and is strongly recommended when the Owner desires such continuity.
(d) Backflow preventer assemblies shall be tested more frequently than specified in Section (a) above, in cases where there is a history of test failures and the Bridgeport Utility Board finds that the degree of hazard involved warrants additional testing. The cost of any additional test(s) will be borne by the Owner. (Passed 10-10-16.)
