The Prier C-534 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-534 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 preventer provides protection against cross-connection of the potable water supply， while venting to eliminate any vacuum. The C-534 has an extended vandal proof lock-shield and comes with a loose key for operation. No special installation tools required.
