MCC-NH Gas Fitters Practice Exam

What is the minimum length required for a sediment trap between the tee and the cap?

1. 1 inch

2. 2 inches

3. 3 inches

4. 4 inches

The correct answer is: 3 inches

The minimum length required for a sediment trap between the tee and the cap is three inches. This specification is crucial in gas fitting as it ensures that any sediment or debris that may accumulate in the gas line can effectively settle and be removed during maintenance. Sediment traps are designed to collect impurities that might otherwise cause blockages or malfunctions in the gas system. Having a three-inch trap provides sufficient space for sediment to gather without obstructing gas flow. This length balances the need for capturing sediment while maintaining system efficiency. If the sediment trap were shorter than this minimum requirement, it might not adequately perform its function, potentially leading to operational issues or safety concerns. Proper implementation of these standards is essential for ensuring the reliability and safety of gas installations.
