§ 51.154  INSTALLATION OF ASSEMBLIES.
   (A)   All backflow prevention assemblies shall be installed in accordance with the specifications furnished by the town and the manufacturer's installation instructions and/or in the latest edition of the North Carolina Building Code (particularly Table 608.1 of the North Carolina Plumbing Code), whichever is most restrictive.
   (B)   All new construction plans and specifications, when required by the North Carolina Building Code and the North Carolina Division of Environmental Health, shall be made available to the town for review and approval and to determine the degree of hazard.
   (C)   Ownership, testing, and maintenance of the assembly shall be the responsibility of the consumer.
   (D)   All double-check valve assemblies must be installed in drainable pits wherever below-ground installation is necessary, in accordance with detailed specifications provided by the town. Double-check valve assemblies may be installed in a vertical position with prior approval from the town, provided the flow of water is in an upward position.
   (E)   Reduced pressure principle backflow prevention assemblies must be installed in a horizontal position (unless specifically designed for vertical installation) and in a location in which no portion of the assembly can become submerged in any substance under any circumstance. Pit and/or below grade installations are prohibited.
   (F)   The installation of any backflow prevention assembly which is not approved by the town must be replaced by one which is approved.
   (G)   The consumer shall make sure all backflow prevention assemblies are working properly upon installation and must furnish the following information to the town within 15 days after a reduced pressure principle backflow preventer (RP), double-check valve assembly (DCVA), pressure vacuum breaker (PVB), double-check detector assembly (DCDA), or reduced pressure principle detector assembly (RPDA) is installed:
      (1)   Service address where assembly is located;
      (2)   Owner (and address, if different from service address);
      (3)   Description of assembly's location;
      (4)   Date of installation;
      (5)   Installer (include name, plumbing company represented, plumbers license number);
      (6)   Type of assembly and size of assembly;
      (7)   Manufacturer, model number, serial number; and
      (8)   Test results/ report.
   (H)   When it is not possible to interrupt water service, provisions shall be made for a "parallel installation" of backflow prevention assemblies. The town will not accept an unprotected bypass around a backflow preventer. Bypass lines will have at least the same degree of protection as the backflow preventer being bypassed.
   (I)   Upon notification by the town, the consumer shall install the appropriate containment assembly not to exceed the following timeframe:
      (1)   Health hazard: 60 days; or
      (2)   Non-health hazard: 90 days.
   (J)   Following installation, all RP, DCVA, PVB, DCDA, and RPDA are required to be tested by a Certified Backflow Prevention Assembly Tester within ten days.
