Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Arrowhead Arrow-Breaker 1/2 in. MPT X 1/2 in. Copper Sweat Anti-Siphon Brass Wall Hydrant is built to deliver reliable outdoor water access with safety and longevity in mind. This frost-proof wall hydrant combines durable brass construction, lead-free compliance, and an integrated anti-siphon valve to guard your drinking water from backflow, even in busy irrigation seasons.

The dual-end configuration (1/2 in MPT feed to 1/2 in copper sweat) simplifies installation by matching common supply lines without excessive adapters. The QuickTurn handle lets you open or close the hydrant with a light touch, even when you’re wearing gloves or working in tight spaces. At 8 inches in length, this hydrant fits neatly on exterior walls while keeping the valve accessible for winterization and routine use.

  • End connections: 1/2 in MPT and 1/2 in copper sweat
  • Anti-siphon: built-in backflow prevention to protect potable water
  • Frost-proof: designed to resist freezing and simplify drainage during cold snaps
  • Flow rate: 18
  • Maximums: 125 psi, 180 °F
  • Material & finish: lead-free brass, rough finish
  • Turn type: QuickTurn for fast, easy operation
  • Brand lineage: Arrowhead and its Arrow-Breaker sub-brand for trusted durability

This wall hydrant is ideal for homeowners, landscaping pros, and rental properties where dependable outdoor water access is essential. Whether you’re watering a lawn, filling a stock tank, or washing equipment, the Arrowhead Arrow-Breaker provides a safe, efficient solution that reduces backflow risk and simplifies maintenance.

Practical tips for install and use:

  • When connecting to a threaded supply, apply Teflon tape to the 1/2 in MPT end to ensure a tight seal and prevent leaks.
  • For copper sweat connection, use appropriate flux and copper soldering techniques to achieve a durable joint.
  • Check the anti-siphon vent periodically to ensure it is clear of debris and functioning properly.
  • Winterize by fully closing the valve before freezing temperatures to leverage frost-proof design and minimize water remaining in the line.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
