What does it mean for a product to be listed in plumbing standards?

When a product is listed in plumbing standards, it signifies that it has undergone a thorough evaluation process and has been determined to be satisfactory for specific applications in plumbing systems. This listing typically means that the product meets or exceeds established safety, performance, and reliability criteria set forth by recognized standards organizations. Such organizations assess products based on standardized tests that evaluate various aspects, including materials, construction, and intended use.

Having a product listed ensures consumers, contractors, and plumbing professionals that the item is appropriate for installation in plumbing systems, which is critical for safety and compliance with building codes. This designation helps protect the end-user by ensuring that the materials used in plumbing applications are trustworthy and suitable for their intended purpose.
