A. Each backflow prevention assembly after initial testing shall be field tested on an annual basis by a commercial testing company selected and coordinated by the consumer. The field test shall occur no later than the annual date of installation. In those instances where the superintendent deems the hazard to be great enough, the superintendent may require field tests at more frequent intervals.

B. If repair or relocation of a backflow prevention assembly is required, each backflow prevention assembly shall be field tested after being repaired or relocated and prior to being placed back into service.

C. A representative from the water supplier may witness the field tests at the discretion of the water supplier. Records of the field tests and all repairs shall be submitted to the water supplier.

D. All expenses related to testing, repairs, relocation, or replacement shall be at the expense of the consumer.

E. In cases where ownership of a backflow preventer is unclear, the water supplier will perform the testing or repairs and shall proportionately charge all customers receiving service through the backflow prevention assembly. (Ord. 1331 § 2, 2016).
