Woodford 34HD Brass Vacuum Breaker

Woodford Model 34HD Vacuum Breaker With Brass Finish.

The Woodford 34HD vacuum breaker is a crucial component used in outdoor faucets (hose bibs) to prevent backflow of water into the potable water supply. Let’s explore its features:

1. Function:

   • The vacuum breaker ensures that water flows in one direction only, preventing contamination of the drinking water system.
   • It prevents backflow, which can occur due to sudden pressure drops (e.g., burst water mains or plumbing issues).

2. Features of the Woodford 34HD Vacuum Breaker:

   • Material: The vacuum breaker is made of durable brass.
   • Finish: The “HD” likely stands for “Heavy Duty”, indicating robust construction suitable for commercial or industrial applications.
   • Hose Connection: It attaches to the hose bib or faucet spout.
   • Spring-Loaded Valve: Inside the vacuum breaker, there’s a spring-loaded valve that allows water to flow out but prevents it from flowing back in.
   • Atmospheric Vent: When water pressure drops, the spring opens, allowing air to enter and break the vacuum, preventing backflow.

3. Installation:

   • Screw the vacuum breaker onto the faucet spout.
   • Attach the hose to the other end.
   • Proper installation ensures that water flows out freely but cannot siphon back into the water supply.

4. Maintenance:

   • Regularly inspect and clean the vacuum breaker to ensure proper functioning.
   • Remove any debris or mineral buildup that could obstruct the valve.
   • Replace the vacuum breaker if it’s damaged or leaking.
