What is the primary role of plumbing codes?

The primary role of plumbing codes is to ensure safe and sanitary plumbing installations. Plumbing codes establish standards and guidelines that protect public health and safety by regulating how plumbing systems are designed, installed, and maintained. These codes address various factors, including the quality of materials used, the proper installation of fixtures and appliances, and the prevention of cross-contamination between potable and non-potable water supplies. By adhering to these codes, plumbers help to minimize the risk of plumbing failures, leaks, and contamination, ultimately safeguarding the well-being of the public.

Other aspects, such as reducing installation costs, focusing on aesthetic design, or improving property values, may be considered in the broader context of construction and real estate, but they are not the primary purpose of plumbing codes. Codes are fundamentally about health and safety, serving as a legal framework to ensure that plumbing work is performed correctly and reliably.
