The Watts LF009-1 Reduced Pressure Zone Lead-Free Backflow Preventer (0124403) is a high-performance system component engineered to deliver premium fluid distribution efficiency and reliability. Built with a heavy-duty lead-free cast copper silicon alloy housing, this unit provides exceptional durability and outstanding resistance to demanding system environments. Its low-maintenance, high-performance architecture makes it an ideal solution for absolute containment control across high-hazard water supply infrastructure lines.
Designed specifically to mitigate health-hazard cross-connections, the LF009 series utilizes a reduced pressure zone (RPZ) safety layout containing two independent check valves coupled alongside an intermediate hydraulically dependent relief valve assembly. This ensures toxic substances and non-potable liquids cannot back-siphon or back-pressure into clean municipal drinking systems. Equipped with two integrated, quarter-turn lead-free ball valves and test cocks for simplified diagnostic check cycles, this inline component delivers permanent safety monitoring, low differential pressure restriction, and complete commercial safety code compliance.
