Services for fire protection are required to be installed with the proper backflow assembly device with a metered bypass. It shall be mandatory for the installation to be made with an approved water flow alarm, as approved by the city and the chief of the fire department, or their delegate, on each such service installation. A water flow alarm is not required for residential fire sprinkler systems, such as flow through or combination type, when the residential service is metered and the system is approved by the fire chief or their designee and the city. It is unlawful for any person to make connection to any unmetered pipe used for fire service purposes, or any tank connected therewith, nor shall the use of any water be permitted through any fire service nor through any pipes, tanks or other fixtures therewith connected for any purpose except the extinguishing of fire on the premises or with prior test notice to the city for fire drill, testing sprinkler systems or fire service mains, except for approved residential flow through systems or combination type systems that are metered. Upon inspection by the city, if any service is found to be in violation of above stipulation the owner or operator may be fined as listed in ACC 13.06.511 in addition to any penalties that may be incurred for violations of Chapter 1.25 ACC by the person or persons making such unlawful connection or use. (Ord. 5849 § 1, 2004; Ord. 5216 § 1, 1999; Ord. 4878 § 3, 1996.)
