(A) All backflow prevention assemblies existing at the time this subchapter is adopted but which do not meet the requirements hereof shall be excluded from the requirements of this subchapter, provided they were approved for the purpose for which they are being used at the time of installation and have been properly maintained so as to function in the manner originally intended.
(B) The previously existing assemblies shall still be subject to the testing requirements of § 51.86 above. Whenever an existing assembly is moved to another location, or requires more than minimum maintenance, or where it is determined by the city to constitute a health hazard, the unit shall be replaced by an approved backflow prevention assembly meeting the requirements of this subchapter and the Uniform Plumbing Code.
