How should plumbing fixtures be inspected in a home?

Plumbing fixtures should be inspected through functional testing, which allows the inspector to evaluate not just the visual condition of the fixtures but also their performance in real-world conditions. This involves turning on faucets and flushing toilets to check water flow, drainage, and any potential issues like clogs or improper drainage. During functional testing, inspectors can also assess the operation of fixtures, such as checking for consistent water temperature, pressure, and any unusual noises, which may indicate underlying problems.

This approach provides a more comprehensive understanding of the plumbing system's functionality and identifies issues that may not be apparent through a visual inspection alone. Visual inspections are important but they do not fully capture functional performance, and simply checking for leaks or replacing fixtures does not provide an assessment of their overall condition or effectiveness.
