In general, pre-existing backflow preventers will not be allowed simply because they were approved before the enactment of this ordinance. The Utility will review the operation and hazard of each facility with backflow preventers and determine acceptability based on operability and present hazard. If the backflow preventers are found unacceptable, they shall be replaced with a backflow prevention device in accordance with this Article.
Pre-existing facilities that have no backflow prevention device and where there is a definite present hazard shall be required to install an appropriate device, regardless of whether their plumbing system was previously approved by the Town.
