Watts introduces two new lead-free backflow prevention products. The LF919 reduced-pressure zone assembly and the LF719 double check valve assembly are designed to protect potable water supplies by preventing the reverse flow of contaminated water. Lead-free bronze body construction ensures compliance with the new national lead-free law that takes effect Jan. 4, 2014. The LF719 and LF919 feature two poppet-style check valves, replaceable check seats and separate access covers for each check for quick servicing. No special maintenance tools are required. The LF719 is designed for use on cross connections in non-health hazard applications, while the LF919 is designed for use on cross connections in health hazard applications and features an intermediate relief valve. Both models are available in 3/4” to 1” sizes with a maximum working pressure of 175 psi.
