There has been much debate on the degree of backflow protection on Class I and II wet-pipe fire sprinkler systems. Much of the controversy centers on whether the water quality in wet-pipe fire sprinkler systems would pose a health hazard if a backflow incident were to occur. The potential requirement for backflow prevention has caused concern in the fire protection industry because of possible hydraulic problems associated with retrofitting existing Class I and II wet-pipe systems. To address this issue, a study was conducted to evaluate the water quality in Class I and II wet-pipe fire sprinkler systems to determine if a public health hazard exists, and to identify methods to effectively safeguard the public in such a case. This paper presents a summary of the results of an 18 month study that was performed with the participation of 26 American and 4 Canadian water purveyors. The project specifically determined the quality of water within Class I and II wet-pipe fire sprinkler systems constructed of black steel (black iron) pipe materials.
