Are you embarking on a plumbing project in Illinois and wondering about the legality of using PEX pipes? Understanding the building codes and regulations governing plumbing materials is crucial to ensure compliance and safety. This comprehensive guide will delve into the Illinois Plumbing Code to answer the question: “Is PEX pipe code in Illinois?”

Plumbing Codes and Regulations in Illinois

The Illinois Plumbing Code governs all plumbing installations, including the use of PEX pipes. The code is enforced by local municipalities and is based on the International Plumbing Code (IPC).

Is PEX Pipe Code in Illinois?

Yes, PEX pipe is code-compliant in Illinois. The IPC allows for the use of PEX pipes in both residential and commercial applications. Specifically, PEX pipes meeting the ASTM F876/F877 standards are permitted for potable water distribution, radiant floor heating, and hydronic heating systems.

Types of PEX Pipes Allowed in Illinois

The Illinois Plumbing Code recognizes three types of PEX pipes:

• PEX-A: Cross-linked polyethylene
• PEX-B: Peroxide cross-linked polyethylene
• PEX-C: Chlorinated polyethylene

All three types of PEX pipes are approved for use in Illinois, provided they meet the ASTM F876/F877 standards.

Installation Requirements for PEX Pipes

To ensure proper installation and performance, PEX pipes must be installed according to the manufacturer’s instructions and the Illinois Plumbing Code. Key installation requirements include:

• Crimping or Clamping: PEX pipes must be secured using crimp rings or clamps designed specifically for PEX.
• Expansion and Contraction: PEX pipes expand and contract with temperature changes. Allow for sufficient expansion and contraction by using expansion loops or fittings.
• Support and Protection: PEX pipes must be supported and protected from damage caused by nails, screws, or other objects.

Benefits of Using PEX Pipes

PEX pipes offer numerous benefits over traditional plumbing materials, such as:

• Flexibility: PEX pipes are flexible and easy to bend, making them ideal for tight spaces and complex installations.
• Corrosion Resistance: PEX pipes are resistant to corrosion and scaling, ensuring long-lasting performance.
• Freeze Resistance: PEX pipes expand when frozen, reducing the risk of bursting.
• Low Maintenance: PEX pipes require minimal maintenance, reducing the need for repairs and replacements.

Summary
