Massachusetts Plumbers Journeyman Practice Exam

What is the required minimum thickness for brass or copper tubing traps?

1. 10 gauge

2. 15 gauge

3. 17 gauge

4. 20 gauge

The correct answer is: 17 gauge

The required minimum thickness for brass or copper tubing traps is 17 gauge. This specification ensures that the material is sufficiently robust to handle the stresses and demands placed on plumbing fixtures and systems. Utilizing materials that meet or exceed this thickness helps prevent issues such as corrosion, leaks, and failures over time, ensuring the integrity and reliability of plumbing installations. Choosing a thickness lower than 17 gauge might not offer the necessary strength and durability required for effective performance in plumbing applications. Each gauge number corresponds to a specific thickness, with lower numbers indicating thicker materials. Thus, 17 gauge strikes a balance between strength and manageability in most standard plumbing settings.
