Description
The Watts F122774 3/4″ Lead Free Reduced Pressure Zone Backflow Preventer Assembly W/Strainer LF909-QT-S prevents reverse flow of contaminated water into clean supply lines by maintaining a controlled pressure zone between inlet and outlet sections in HVAC systems. It uses a reduced pressure chamber with internal check assemblies that open and close based on pressure differentials, ensuring backflow is directed safely away from potable water systems. The integrated strainer captures debris before it enters the valve body, reducing internal blockage during operation. With a 3/4″ threaded connection and 150 PSI rating, it integrates into plumbing networks where regulated water flow separation is required across distribution systems.
