Illinois Plumbing Code Practice

The prohibition against fittings that do not conform to the appropriate standards is rooted in ensuring safety, reliability, and compliance with both the Illinois Plumbing Code and national standards. The code emphasizes the use of materials that have been tested and certified to meet specific safety and performance criteria. This is essential for preventing plumbing failures, leaks, and potential hazards that could arise from the use of substandard or non-compliant fittings.

Manufacturers provide certifications that indicate their products meet the necessary requirements for plumbing systems. Using fittings that adhere to established standards guarantees that they can withstand the pressures, temperatures, and environmental conditions they will face in a plumbing installation. Compliance also ensures compatibility with other plumbing materials and systems, further enhancing the overall integrity of the plumbing infrastructure.

In contrast, the other types of fittings listed, such as brass, CPVC, and stainless steel, are generally acceptable in plumbing installations as long as they meet the required standards. Each of these materials has established qualities that align with plumbing code specifications, being widely used in various applications depending on the requirements of the installation.
