Which principle should guide the opinions expressed by inspectors?

The opinions expressed by inspectors should be guided primarily by education and experience. This principle is essential because it ensures that inspectors rely on credible knowledge, best practices, and technical expertise when evaluating septic systems. An inspector's formal training provides a foundational understanding of the regulations, installation practices, and maintenance requirements that are critical to effective inspections.

Moreover, experience builds upon this knowledge by allowing inspectors to interpret and apply their training in real-world situations. Through hands-on evaluations, inspectors develop a nuanced understanding of septic systems and how factors such as soil type, system age, and usage can affect performance and compliance with local codes. This combination of education and experience enables inspectors to provide informed, objective assessments that prioritize public health and safety.

In contrast, personal intuition may vary greatly among individuals and lacks the foundation necessary for consistent, reliable inspections. Predominant community beliefs and market trends can change over time and may not reflect the technical standards or regulations governing septic systems. Therefore, grounding opinions in education and experience ensures that inspectors maintain professional integrity and uphold the standards of the industry.
