(a) Backflow preventer assemblies shall be tested and inspected at least annually.
(b) Periodic testing shall be performed by a WVBPH certified tester. This testing will be done at the Owner’s expense.
(c) Any backflow preventer assembly which fails during a periodic test will be repaired or replaced. When repairs are necessary, upon completion of the repair, the assembly will be retested at the Owner’s 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 insuring uninterrupted water service during testing or repair of one of the assemblies and is strongly recommended when the Owner desires such continuity.
(d) Backflow preventer assemblies will be tested more frequently than specified in (a) above in cases where there is a history of test failures and the Water Purveyor feels that due to the degree of hazard involved, additional testing is warranted. Cost of the additional tests will be borne by the Owner.
