What is the main purpose of a plumbing code?

The main purpose of a plumbing code is to ensure the safe and efficient installation and maintenance of plumbing systems. Plumbing codes are established to create uniform standards that protect public health, safety, and welfare. They address various aspects of plumbing, including design, materials, methods of installation, and maintenance practices, with the goal of preventing hazards such as leaks, contamination of drinking water, and ensuring comprehensive drainage and wastewater management.

This holistic approach ensures that plumbing systems function correctly and reliably over time, safeguarding both users and the environment. Adopting a plumbing code helps localities establish minimum requirements that all contractors and plumbers must follow, ultimately leading to safer infrastructure for communities.

Other options focus on specific elements that are part of the broader scope covered by plumbing codes, such as standardizing materials or addressing costs, but they don't capture the comprehensive objective of promoting safety and functionality as effectively as the focus on installation and maintenance does.
