Drip legs in gas pipes must always point in which direction?

Upward
Sideward
Downward
Outward

The correct answer is: Downward

Drip legs in gas pipes are designed to prevent moisture and contaminants from accumulating in the gas lines. When a drip leg is installed, it must point downward so that any condensate can effectively settle and collect in the leg. This design allows for easy drainage of the condensation that may form due to temperature fluctuations within the gas line, ensuring that the gas remains clean and that the system operates efficiently. By directing the drip leg downward, any liquid that accumulates can flow away from critical components of the gas delivery system, reducing the risk of corrosion, blockages, or other potential issues that could arise if moisture were to enter the gas appliance or ignition system. This strategic placement is essential for maintaining the overall integrity and function of the gas piping system.
