What is the primary concern when inspecting underground plumbing?

The primary concern when inspecting underground plumbing is corrosion or damage that can lead to leaks or contamination. This is vital because underground pipes are often exposed to elements such as soil conditions, moisture, and varying temperatures, which can accelerate corrosion and lead to structural weaknesses. If pipes corrode or become damaged, it can not only result in leaks that waste water but also pose significant health risks due to the potential for contamination of drinking water supplies.

The integrity of underground plumbing systems is crucial for maintaining safe and efficient water distributions, and any signs of wear, corrosion, or physical damage should be addressed immediately to prevent more serious issues. This concern is essential as it directly relates to public health, safety, and environmental impact, making it the top priority during inspections.
