Are all plastic vent pipes in mitigation systems required to be made of Schedule 40 PVC, ABS, or equivalent material?

The statement is false because not all plastic vent pipes in mitigation systems are mandated to be made of Schedule 40 PVC, ABS, or an equivalent material. While Schedule 40 PVC and ABS are commonly accepted materials due to their durability and ability to withstand the environmental conditions typically found in radon mitigation systems, other materials may also be acceptable depending on local building codes and regulations.

Additionally, factors such as the specific requirements of a mitigation system, the installation environment, and compatibility with other components in the system can influence the choice of pipe material. Therefore, it is important for practitioners to familiarize themselves with local regulations and guidelines that dictate allowable materials for vent pipes in radon mitigation systems, which may include alternatives not specified in the question. This flexibility allows for a tailored approach to installation that can better suit the unique needs of each situation, ensuring effective radon mitigation while adhering to safety standards.
