Prier Products 1/2 in. x 6 in. Brass MPT x SWT Self-Draining Heavy Duty Frost Free Anti-Siphon Wall Hydrant

6 in. Prier Products Heavy Duty Residential Self-Draining Anti-Siphon Wall Hydrant. The Prier C-434 provides a year round source of water to areas of structures that are subject to freezing temperatures. The hydrant valve is connected to the supply piping in the heated portion of the structure, eliminating the possibility of freezing. To assure freeze protection, the hydrant will drain even with the hose attached and under pressure without spray-back. The C-434 combines freeze less hydrant features with self-draining, anti-siphon and two backflow check valves. Upon closure, the valve drains even with closed end hose attached. Prier's C-434 is satin nickel plated for a long lasting finish that will not rust or tarnish. The large flange is pitched to drain, has enclosed screw holes and is easy to install with no special installation tools required.
