Watts 0391005 1-1/4" LF009M2QT Zone Assembly. The Reduced Pressure Zone Assemblies prevent reverse flow of used or dirty water from entering back into the water supply. Back siphonage and backpressure can occur from time to time and this Backflow Preventer is one of the best products to avoid those things from occurring. The 909 series all feature Silicon Alloy body construction, bronze ball valve shutoffs, and bronze test cocks. Series LF009 also features an air in and water out design principle for protection during emergency combined back siphonage and backpressure conditions.
