Which fitting is required for making the yoke vent intersection?

• A. Elbow
• B. Wye Branch
• C. Tee
• D. Reducer

Answer: (B)

The key idea is that vent connections to a drainage line are best made with a wye branch. A wye provides a 45-degree branch off the main line, giving a smooth, gradual connection for the vent that allows air to rise without creating sharp turns or dead spots where liquids can collect. This helps maintain proper venting and drainage flow. An elbow would simply bend the pipe with a sharp turn, which isn’t suitable for a vent connection. A tee creates a perpendicular intersection that can impede vent flow or create drainage issues. A reducer changes size but doesn’t provide the proper branch for the vent. Therefore, the correct fitting is the wye branch.
