Woodford 34HA-BR Vacuum Breaker In Brass Finish For Models 20, 25, 60, and 65.

he Woodford 34HA-BR vacuum breaker is a crucial component in outdoor faucets (hose bibs) to prevent backflow of water into the potable water supply. Let’s dive into the details:

1. Function:

   • A vacuum breaker is designed to prevent contamination of the drinking water system by ensuring that water flows in one direction only.
   • It prevents backflow, which can occur when there’s a sudden drop in water pressure (e.g., due to a burst water main or other plumbing issues).

2. Features:

   • The Woodford 34HA-BR vacuum breaker typically has the following features:
     • Hose Connection: It attaches to the hose bib or faucet spout.
     • Spring-Loaded Valve: The vacuum breaker contains 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.
     • Brass Construction: The “BR” in the model number likely stands for brass, indicating a durable and corrosion-resistant material.

3. Installation:

   • The vacuum breaker is usually installed on the spout of an outdoor faucet.
   • It screws onto the faucet spout, and the hose is attached to the other end.
   • Proper installation ensures that water flows out freely but cannot siphon back into the water supply.

4. Maintenance:

   • Regular inspection and cleaning are essential to ensure proper functioning.
   • Check for debris or mineral buildup that could obstruct the valve.
   • Replace the vacuum breaker if it’s damaged or leaking.

5. Compliance:

   • Vacuum breakers are often required by plumbing codes to protect against backflow.
   • They are commonly used in outdoor faucets, irrigation systems, and other hose connections.

Remember that proper installation and maintenance are crucial for the effective operation of the vacuum breaker.
