A. If the Director determines, after inspection of the customer’s system, that a backflow prevention method less restrictive than that required in § 8.20.030 will provide adequate protection of the public potable water supply from the degree of hazard potential by the customer’s water system, the Department may, in its sole discretion, modify the requirements of the § 8.20.030 accordingly.
B. Class 1 and 2 fire sprinkler systems of nonpotable material installed prior to August 8, 1991, may be given the option to retrofit with an appropriate backflow prevention assembly immediately or perform a Quarterly Flow and Valve Confidence Test. Tests are to be performed by an appropriately licensed contractor and results submitted to the Director within 30 days following the inspection. Failure of 2 consecutive tests may result in the immediate retrofit of the fire sprinkler system with an appropriate backflow prevention assembly.
