What is the role of a plumbing inspector?

The role of a plumbing inspector primarily involves evaluating plumbing installations to ensure they comply with relevant codes and regulations. This responsibility is crucial because it helps maintain safety, functionality, and efficiency within plumbing systems. The inspector checks various aspects of the installation, including the materials used, the methods of installation, and adherence to local plumbing codes. Through inspections, the plumbing inspector helps prevent potential hazards that could arise from violations, ensuring that all plumbing systems operate safely and effectively.

While repairing plumbing systems, designing layouts, and training plumbers are important aspects of the plumbing profession, they fall under different responsibilities. The inspector's primary focus is on compliance assessment rather than hands-on work in repairs, design, or training. Therefore, the correct answer accurately reflects the primary function of a plumbing inspector in safeguarding public health and the environment by ensuring that plumbing systems meet established standards.
