During the plumbing inspection, what measurement is not required by the inspector?

The measurement that is not typically required by the inspector during a plumbing inspection is the water flow rate. While understanding the flow rate can be beneficial in assessing the overall performance and efficiency of the plumbing system, it is often not a mandated or standard part of a home inspection checklist. Inspectors typically focus on identifying visible defects, ensuring compliance with relevant codes, and recognizing any potential health or safety risks associated with the plumbing system.

In contrast, measuring pipe diameter is essential for assessing compatibility with plumbing fixtures and overall system performance. Pressure readings are important to determine whether the water supply is adequate and to identify any possible issues with the plumbing system. The thickness of piping insulation can also be significant for energy efficiency and preventing condensation problems. Therefore, while flow rate information can provide insights into system functionality, it is not a primary requirement for inspectors during a standard plumbing inspection.
