41-2168. Fire protection systems; definitions

A. All backflow prevention equipment installed on class 1 and class 2 fire protection systems shall comply with state fire code standards.

B. Check valve assemblies installed on class 1 or class 2 fire protection systems as backflow protection equipment pursuant to this section shall be inspected and maintained in accordance with the procedures identified in the national fire protection association publication 25 for water based fire protection systems, 1992 edition, to determine compliance with the minimum design standards established by the state fire code. Inspections of check valve assemblies installed on class 1 or class 2 fire protection systems shall be performed on an annual basis with records of the inspections provided to the local fire department and drinking water provider.

C. Any malfunction or abnormality with a check valve assembly installed on class 1 or class 2 fire protection systems shall be reported within twenty-four hours to the local fire department and drinking water provider.

D. A fire code authority may establish guidelines for the installation of backflow prevention equipment on a class 1 or class 2 fire protection system that exceeds the minimum standards established by the state fire code if the backflow prevention equipment is approved for use on class 1 or class 2 fire protection systems pursuant to section 1.102 of the uniform fire code, 1988 edition.

E. A fire code authority or a drinking water provider may require the installation of backflow prevention equipment on class 1 and class 2 fire protection systems that exceeds the minimum standards established by the state fire code if a special backflow condition is identified. The use of nonpotable pipe in a fire protection system does not by itself constitute a special backflow condition. The drinking water provider shall consult with the fire code authority and provide the fire code authority with an opportunity to comment before installing or requiring the installation of backflow equipment that exceeds the minimum standards established by the state fire code.
