PRIER C-144 Freezeless Wall Hydrant with Integral Vacuum Breaker – 1/2" MPT x SWT, 8" Insertion Length

The PRIER C-144 Series offers a heavy-duty, freeze-resistant wall hydrant designed for exterior hose connections in cold climates.

Installation Considerations

For freeze protection to function correctly, the hydrant must be installed with a downward pitch toward the spout. The unit should be tied into the building’s heated water supply line. Secure flange mounting is critical to prevent rotation and ensure long-term seal integrity. Installers should follow all local code requirements. A licensed plumber is recommended to ensure compliant and trouble-free installation.
