§ 50.83  INSTALLATION, TESTING AND MAINTENANCE OF BACKFLOW PREVENTION ASSEMBLIES.
   (A)   All backflow prevention assemblies shall be installed in accordance with the manufacturer's instructions. Only backflow preventers approved by the Public Works Director, American Society of Sanitary Engineers (ASSE) or the American Water Works Association (AWWA), or USC shall be used.
   (B)   All backflow prevention assemblies required by this section must be installed and maintained on the customer's premises as part of the customer's water system.
   (C)   Ownership, testing, and maintenance of the backflow prevention section assembly will be the responsibility of the customer. Each assembly required in this subchapter must be functioning properly at all times.
   (D)   A certified tester shall conduct testing of backflow prevention assemblies at the customer's expense. Tests shall be conducted upon installation and annually thereafter with a record of all testing and repairs retained by the customer. Each customer must send a copy of the certified record for each test or repair to the town within 30 days after the completion of each test or repair. Such records must be maintained on forms provided by the town.
   (E)   Each backflow prevention assembly required under this section must be accessible to the town.
   (F)   When it is not possible to interrupt water service, the customer shall provide for the parallel installation of an approved backflow prevention assembly. A bypass around a backflow preventer when the assembly is in need of testing, repair or replacement is not allowed.
   (G)   Double check valve assemblies must be installed in drainable pits whenever below-ground installation is necessary.
   (H)   Reduced pressure principle assemblies must be installed in a horizontal position and in a location in which no portion of the assembly can become submerged in any substance under any circumstances (pit and/or below grade installations are prohibited).
   (I)   Any time that repairs to backflow assemblies are deemed necessary, whether through annual testing or routine inspection by the owner or by the town, these repairs must be completed within a time specified below in accordance with the degree of hazard. Repairs must be made to health-hazard facilities in 14 days. Repairs must be made to non-health-hazard facilities in 21 days. Failure to comply can result in termination of a customer's water service.
   (J)   If the town determines that a backflow prevention assembly is required to be installed on a customer's private water system, the customer will be notified in writing of the approved backflow prevention assembly which is required. On existing systems, the customer will have the following time periods within which to install the specified backflow prevention assembly:
      (1)   Health hazard facility - 60 days;
      (2)   Non-health hazard facility - 90 days.
   (K)   All new construction plans and specifications shall be made available to the town for approval and to determine the degree of hazard.
   (L)   The customer shall notify the town when the nature of the use of property changes so as to change the hazard classification of the property.
