1/2" x 4" Freezeless Wall Hydrant with Anti-Siphon Breaker.

PRIER C-144 Freezeless Wall Hydrant with Integral Vacuum Breaker – 1/2" MPT x SWT, 4" Insertion

The PRIER C-144 is a heavy-duty freezeless wall hydrant engineered for year-round performance in cold climates. Designed for connection to supply lines within the heated envelope of a structure, the C-144 prevents freeze-related failures while offering backflow protection through an integrated vacuum breaker. Its robust construction and industry-proven reliability make it a preferred solution for residential and light commercial applications.

Designed for Harsh Conditions

Constructed from solid brass and finished with a corrosion-resistant satin nickel plating, the C-144 is built to withstand exposure and demanding environments. Its full-turn operating mechanism ensures smooth water control, and the integral backflow prevention components meet ASSE 1019 and CSA B125.1 standards. The hydrant automatically drains when shut off—provided it is installed with proper downward pitch—eliminating trapped water and preventing freeze damage.

Contractor-Focused Benefits

• Vacuum Breaker with Backflow Check – Provides built-in anti-siphon protection to prevent contamination of the potable supply.
• Solid Brass Construction – Durable material resists corrosion and mechanical wear over time.
• 360° Turn Valve Operation – Offers full control over flow with smooth shutoff and reduced seat wear.
• Drainage Pitch Cast into Flange – Aids proper drainage to prevent freezing when installed correctly.
• AFG Teflon® Packing – Reduces maintenance with long-lasting, easy-to-service sealing.
• Lock Shield Cap – Reinforces the stem connection and enhances tamper resistance.

Installation Notes

To ensure proper freeze protection, the hydrant must be installed with a downward pitch toward the outlet. The valve stem and supply connection must remain in a heated area of the structure. For best results and compliance with local plumbing codes, installation by a licensed contractor is strongly recommended. The flange is cast with enclosed screw holes and an orientation mark for simplified and secure wall mounting.

Applications

Ideal for hose bibb access in single-family homes, multi-unit dwellings, or light commercial buildings. Suitable for installations where freeze protection and backflow prevention are required in one integrated unit.
