The 3/4" Febco 860U Reduced Pressure Zone (RPZ) backflow preventer was introduced in 1997 and is still in production. The "U" suffix stands for union ball valves. The 860U uses the same parts as the 860. Known as Febcos "Master Series", the 860 feature an in-line check design with bottom mounted relief valve. Check assemblies are self contained modular style. The relief valve is a stem type with internal sensing line. In 2010, the LF860 was introduced as a lead free model to meet new plumbing codes. Both original and lead free versions use the same repair parts. No special tools are required for servicing.
