What is the purpose of a wrap around in plumbing?

• A. To support heavy loads
• B. To mark a straight line around a pipe
• C. To secure pipe joints
• D. To prevent leaks

Answer: (B)

The purpose of a wrap-around in plumbing is to mark a straight line around a pipe. This is crucial for ensuring that pipes are cut accurately and installed correctly. By creating a straight reference line, plumbers can maintain proper alignment and uniformity during the fitting and joining processes. This technique aids not only in achieving a neat appearance but also ensures that connections are made properly, which is essential for overall system performance.

While other choices may relate to aspects of plumbing, marking a straight line is specifically what a wrap-around is designed for, making it a fundamental tool when precision is necessary in installations.
