What material should cleanout plugs be made of for new work?

Cleanout plugs are designed to provide access to plumbing systems for cleaning and maintenance. When considering materials for new construction, it's essential that the choice balances durability, resistance to corrosion, and compatibility with the surrounding plumbing system.

Plastic is often utilized for its lightweight nature, resistance to corrosion, and cost-effectiveness. In many plumbing applications, especially those involving plastic pipe systems, using plastic cleanout plugs can ensure consistent material compatibility and decrease the likelihood of leaks.

On the other hand, heavy brass plugs are also a suitable option due to their robustness, long-lasting properties, and resistance to chemical corrosion. Brass is commonly used in various plumbing applications and can withstand high-pressure situations, making it a reliable choice for cleanout plugs in metal piping systems.

Therefore, the answer recognizing either plastic or heavy brass as acceptable materials reflects an understanding of the diverse requirements of plumbing systems and the varying conditions they face. This versatility allows contractors to choose the most appropriate material based on the specifics of the plumbing installation while adhering to industry standards.
