What should be prioritized during an inspection of plumbing systems?

During an inspection of plumbing systems, the primary focus should be on functional efficiency and compliance with codes. This encompasses ensuring that all plumbing components operate as intended, which includes checking the proper flow of water, drainage, and the absence of leaks. Compliance with local building codes is crucial since these regulations are established to ensure safety, sustainability, and reliability of plumbing systems. By prioritizing these aspects, inspectors help to ensure that systems not only function correctly but also meet legal standards which safeguard against failures that could result in property damage or health hazards.

In contrast, while overall aesthetic and color of fixtures is important for design, it does not impact the plumbing system's functionality or safety. Similarly, the brand and model of plumbing components might influence quality and reliability but are not as critical during an inspection as the operational aspects and compliance with codes. Cost-effectiveness, while a consideration in material selection, should not take precedence in an inspection context where safety and functionality are paramount.
