Reliable outdoor protection for frost-proof hydrants

Outdoor plumbing deserves equipment that guards against winter-related challenges and backflow. The Arrowhead PK1390 Replacement Self-Draining Vacuum Breaker is built for frost-proof wall hydrants with fine threads, and it will not connect to hose-threaded faucets. This focused upgrade helps outdoor systems maintain proper drainage and backflow control without overhauling existing setups.

Key benefits at a glance

  • Efficient self-draining design that releases residual water when the faucet is shut off, reducing the risk of freeze-related issues.
  • Durable red brass body with 80-83% copper content, complemented by nickel plating for weather resistance.
  • Reliable backflow prevention to keep outdoor plumbing isolated from potentially contaminated water.
  • Easy installation with fine machine threads, compatible with 485BFP and 486BFP frost-proof hydrants.
  • ASSE 1019 approved and IAMPO certified for quality assurance.
  • Not intended for potable water use.

Easy to install and versatile

Designed for straightforward integration into existing systems or new installations, the PK1390’s fine-thread connection makes it suitable for a range of outdoor fixtures beyond basic hydrants. It can replace leaking vacuum breakers on compatible components without complicated steps.

  • Ideal for upgrades in existing outdoor setups without major plumbing changes.
  • Fits frost-proof wall hydrants commonly found on exterior walls.

What to expect in real-world use

The self-draining action helps minimize standing water after use, which can contribute to easier winter maintenance. The rugged metal construction offers long-term durability, while the nickel finish helps shield the unit from the elements over time.
