  1. The Company may require a customer to pay for and to have installed a backflow-prevention assembly if A.A.C. R18-4-215(B) or (C) applies. The Company may also require a customer to pay for and to have installed a backflow prevention assembly for all fire line connections.

  2. A backflow-prevention assembly required to be installed by the customer under Paragraph 1 of this tariff shall comply with the requirements set forth in A.A.C. R18-4-215(D) and (E).

  3. Assemblies for domestic and irrigation service must be lead free Reduced Pressure Principle assemblies. Lead free Double Check Detector Assemblies are the minimum protection required for class 1 or 2 fire protection systems.

  4. Subject to the provisions of A.A.C. R14-2-407 and R14-2-410, and in accordance with this tariff, the Company may terminate service or may deny service to a customer who fails to install a backflow-prevention assembly as required by this tariff.

  5. The Company shall give any existing customer who is required to install a backflow-prevention assembly written notice of said requirement. If A.A.C. R14-2-410(B)(1)(a) is not applicable, the customer shall be given thirty (30) days from the time such written notice is received in which to comply with this notice. If the customer can show good cause as to why they cannot install the backflow-prevention assembly within thirty (30) days, the Company or Commission Staff may suspend this requirement for an additional ninety (90) days.

  6. Testing shall be in conformance with the requirements of A.A.C. R18-4-215(F). The Company may require the customer to pay to have the backflow- prevention assembly tested so long as the Company does not require more than two (2) tests per year.. Testing on backflow assemblies intended for permanent placement can only occur through permanent plumbing.

  7. The customer shall provide the Company with records of installation and testing within ten (10) days of such work and in the manner prescribed by the Company for submission of records. For each backflow-prevention assembly, these records shall include:

        1. assembly identification number and description;
        2. location;
        3. date(s) of test(s);
        4. description of repairs and recommendations for repairs made by tester; and
        5. the tester’s name and certificate number.

  8. In the event the backflow-prevention assembly does not function properly or fails any test, and an obvious hazard as contemplated under A.A.C. R14-2-410(B)(1)(a) exists, the Company may terminate service immediately and without notice. The backflow-prevention assembly shall be repaired or replaced by the customer and retested.

  9. In the event the backflow-prevention assembly does not function properly or fails any test, or in the event that a customer fails to comply with the testing requirement, and A.A.C. R14-2-410(B)(1)(a) is not applicable, the backflow- prevention assembly shall be repaired or replaced within fourteen (14) days of the initial discovery of the deficiency in the assembly or its function. Failure to remedy the deficiency or dysfunction of the assembly, or failure to retest, shall be grounds for termination of water service in accordance with A.A.C. R14-2-410.
