Wall Hydrants

When outdoor watering access meets winter weather, you need more than a simple hose bibb — you need a properly engineered wall hydrant. Our Wall Hydrants collection offers frost-proof, anti-siphon and heavy-duty outdoor hydrants designed for landscape irrigation, maintenance wash-downs and commercial settings.

Also called “non-freeze wall hydrants” or “frost-proof outdoor faucets,” these valves are built so that the shut-off mechanism remains inside heated space and residual water drains out to prevent freeze damage. Many models include integrated vacuum breakers or backflow preventers to ensure compliance and protect potable water systems.

In this collection you’ll find:

  • Frost-proof wall hydrants that drain when turned off, protecting the pipe in freezing climates.

  • Anti-siphon / built-in vacuum breaker models designed for code compliance and safe water systems.

  • Multiple stem lengths and connection types to match wall thickness and pipe materials (sweat, threaded, PEX). 

  • Commercial-grade hydrants with key-oriented operation or lock-shield covers for multi-unit or public spaces.

  • Durable materials—heavy brass bodies, corrosion-resistant components, and design details intended for long life and reliability. 

Why shop with Big Frog Supply? We specialize in irrigation, plumbing and lighting — meaning you get hydrants that do more than just deliver water. We help you choose the correct stem length, install angle (to allow drainage), connection type and freeze-protection method so you don’t call us back in the spring.

When you install a wall hydrant, slope the flange slightly downward (3-5°) toward the exterior so the barrel drains properly. Confirm your local code’s requirement for vacuum breakers or anti-siphon features. Choose the proper stem length for your wall thickness and insulation depth—and always remove the garden hose at season’s end to prevent freeze damage.

Browse through the collection, find the right wall hydrant for your climate and system, and install with confidence — ready for year-round performance.
