What is the primary concern related to plumbing pipes installed underground?

The primary concern related to plumbing pipes installed underground is corrosion and maintenance. Underground pipes are often subjected to various environmental factors that can lead to corrosion. Soil conditions, moisture levels, and the presence of certain chemicals can all contribute to the degradation of the pipe material over time. If corrosion occurs, it may lead to leaks or pipe failure, which can be costly and complex to repair, especially since the pipes are buried and not easily accessible.

Maintenance becomes a significant concern because, unlike above-ground piping, underground pipes are out of sight and may not be regularly inspected. Issues that arise can go unnoticed until they cause significant problems, necessitating extensive excavation for repairs. Thus, the integrity and longevity of underground plumbing systems heavily depend on understanding and managing corrosion risks, making this a primary concern for plumbing contractors.
