What material is not allowed for condensate drains?

• A. Copper
• B. Plastic
• C. Brass
• D. PVC

Answer: (C)

The use of brass for condensate drains is not permitted due to its susceptibility to corrosion in the presence of water and other substances commonly found in condensate. Corrosion can lead to system failures and leaks, which poses a safety hazard and can damage other components of the gas fitting infrastructure. In contrast, materials like copper, plastic, and PVC are typically allowed and preferred for condensate drains. Copper is durable and resistant to corrosion, while plastic and PVC are non-corrosive and lightweight, making them suitable for handling condensate. Therefore, the choice of brass highlights its unsuitability in this application, emphasizing the importance of selecting the right materials to ensure longevity and safety in gas fitting installations.
