What must inspectors check for in plumbing systems?

Inspectors must check for pipe materials and joint fittings in plumbing systems because these elements are critical to ensuring the overall safety, functionality, and compliance of plumbing installations. The materials used for pipes must meet specific standards to withstand pressure and resist corrosion, while the fittings need to provide secure, leak-proof connections. This assessment is essential for preventing potential leaks or failures that could lead to water damage and health hazards.

In a plumbing inspection, verifying the type of materials (such as PVC, copper, or galvanized steel) ensures that they are suitable for the intended use and compliant with local codes. Additionally, inspecting joint fittings is crucial since improper installations can result in leaks that compromise the integrity of the plumbing system.

Other aspects, like aesthetics and age of fixtures or sanitation practices, while important for general maintenance or user experience, do not directly affect the fundamental operational integrity and safety of plumbing systems in the same way that the quality of materials and fittings does. Hence, the emphasis on pipe materials and joint fittings aligns with best practices in plumbing inspections.
