Prier - Anti-Siphon Wall Hydrant - 1/2"Wirsbo - C-434W

Spec Sheet   Install Manual

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.

The C-434 has all of the features of the historically proven PRIER C-134, with additional protection of a self-draining anti-siphon backflow check valve. The vacuum breaker/backflow preventor provides protection against cross-connection of the potable water supply, while venting to eliminate any vacuum. No special installation tools are required.

The C-434 is available in stock lengths from 1 ½" to 24", with longer lengths available upon request.
