(A) All testable backflow devices shall be tested and inspected at least annually.
(B) Periodic testing shall be performed by a certified tester from a list provided by the utility. This testing will be done at the owner’s expense.
(C) Any backflow preventer which fails during a periodic test will be repaired or replaced. When repairs are necessary, upon completion of the repair, the device will be re-tested at the owner’s expense to ensure correct operation. High hazard situations will not be allowed to continue if the backflow preventer fails the test and cannot be repaired immediately. In other situations, a compliance date of not more than 30 days after the test date will be established. The owner is responsible for spare parts, repair tools, or a replacement device. Parallel installation of two devices is an effective means of the owner ensuring uninterrupted water service during testing or repair of devices, and is strongly recommended when the owner desires the continuity.
(D) Backflow prevention devices will be tested more frequently than specified in division (A) above if the utility feels that there is a history of test failures. Cost of additional testing will be borne by the owner. Any circumstance not covered by this chapter or any of the authorities in § 52.01(B) shall be left to the judgment of the Administrator, or designee.
