Watts adds two lead-free backflow prevention products: LF919, reduced-pressure zone assembly, and LF719 (pictured), double-check valve assembly. Both assemblies are designed to protect water supplies by preventing the reverse flow of contaminated water. Lead-free bronze body construction complies with the upcoming national lead-free law. The assemblies feature two poppet-style check valves, replaceable check seats and separate access covers for quick servicing of each check. No special maintenance tools are required. Both models are available in sizes 3/4” to 1” with a maximum working pressure of 175 psi.
