Cross-linked polyethylene (PEX) pipe may be used in sizes __________________.

• A. Any
• B. 1/2"-1"
• C. 1"-3"

Answer: (B)

Cross-linked polyethylene (PEX) pipe is commonly utilized in residential and commercial plumbing for various applications, primarily due to its flexibility, resistance to scale and chlorine, lower shipping costs, and ease of installation. The standard range for PEX plumbing applications is typically from 1/2 inch to 1 inch in diameter. This size range is particularly suited for water supply lines, making it a popular choice for residential plumbing systems where smaller, flexible pipes can navigate walls and tight spaces effectively. Using PEX pipe within this specified size range ensures compliance with plumbing codes and industry standards, which are established to ensure performance, safety, and reliability in plumbing systems. In contrast, while PEX can be manufactured in larger sizes beyond 1 inch, its use in larger diameters may not be as prevalent or practical for standard residential applications governed by plumbing codes, which can limit its acceptance to the more common sizing found in household installations.
