Protect your water system from the effects of backflow contamination and save money doing it! Pre-rinse units are subject to backflow because of the flexible air gap; the spray valve can reach the overflow level of the sink. Should a backflow condition occur, contaminated water is “sucked-up” into the water system which can pose serious health risks to all who consume the contaminated water. By using Fisher's NSF approved in-line backflow preventer, you virtually eliminate any threat of backflow contamination. As an added bonus, an Ultra Spray Valve is included with this kit. With the pipe-to-hose adapter, this kit will fit ALL pre-rinse units!
