PRIER C-144 Freezeless Wall Hydrant with Integral Vacuum Breaker – 1/2" MPT x SWT, 12" Insertion Length

The PRIER C-144 is a heavy-duty freezeless wall hydrant designed for year-round water access in cold climates. It connects to the building’s water supply within the heated portion of the structure and drains when shut off, preventing freeze damage. The C-144 is built from solid brass and includes an ASSE 1019-certified vacuum breaker and integral backflow check valve, ensuring reliable operation and protection of potable water systems.

Built for Cold Weather, Backed by Code Compliance
