§ 51.21 BACKFLOW ASSEMBLY TESTING AND INSTALLATION.
   (A)   All backflow prevention assemblies shall be tested upon installation by a recognized backflow assembly tester and certified to be operating within specifications. Backflow prevention assemblies which are installed to provide protection against high health hazards must also be tested and certified to be operating within specifications at least annually by a recognized backflow prevention device tester.
   (B)   Backflow assembly testing and installation shall be completed as required by the Texas Commission on Environmental Quality (TCEQ), Texas Administrative Code, Title 30, Chapter 290, § 290.44(H).
   (C)   It shall be the duty of the customer at any premise where backflow prevention assemblies are installed to have a certified inspection and operational tests conducted annually. In those instances where the city deems the hazard to be deleterious to human health, customer service inspection certifications may be required semiannually. Inspections and tests shall be at the expense of the customer or customer representative and shall be performed by a certified backflow technician.
   (D)   Assemblies shall be repaired, overhauled, or replaced at the expense of the customer whenever said assemblies are found to be defective. Records of such tests, repairs, and overhaul shall be kept and submitted to the city within five days of the test, repairs, or overhaul of each backflow prevention assembly.
   (E)   No device or assembly shall be removed from use, relocated, or other device or assembly substituted without the approval of the city. Whenever the existing assembly is moved from the present location, requires more than minimum maintenance, or when the city finds that the maintenance constitutes a hazard to health, the unit shall be replaced by a backflow prevention assembly complying with requirements of this section and the current adopted Plumbing Code of the city.
   (F)   A test report must be completed by the recognized backflow prevention assembly tester for each assembly tested. The signed and dated original must be submitted to the city, Community Development Division, within five days of test.
   (G)   A recognized backflow prevention assembly tester must have completed a Texas Commission on Environmental Quality (TCEQ) approved course on cross-connection control and backflow prevention and pass an examination administered by the TCEQ or its designated agent.
