The Ames 3 Inch Reduced Pressure Backflow Preventer Valve is engineered to protect residential fire protection and potable water systems from contamination risks. Installed within fire suppression and water supply assemblies, this valve integrates backflow prevention with real-time hazard alerts using a sensitive pressure differential mechanism designed for low-pressure loss.
It satisfies strict code compliance requirements for water supply protection and installation standards under NFPA 13 and NFPA 25. This assembly meets commercial trade requirements by incorporating grooved end connections that comply with AWWA C606 standards to streamline workflow, accelerate project timelines, and allow secure installation.
