Are cast iron cleanout plugs allowed in plumbing installations?

In plumbing installations, the use of cast iron cleanout plugs is not allowed due to concerns related to corrosion, weight, and the ease of access that modern materials provide. Generally, plumbing codes and regulations mandate the use of materials that are more suitable for maintaining sanitary conditions and ensuring easier maintenance for plumbing systems.

The focus on using non-corrosive materials, such as plastic or other lightweight alternatives, helps ensure the longevity of the plumbing installation while allowing for efficient access and cleaning. By enforcing guidelines that restrict the use of cast iron in this context, regulations aim to promote safety and functionality. As a result, opting for approved materials enhances the overall reliability of plumbing systems and supports compliance with industry standards.
