What does a drip leg or sediment trap do in a piping system?

A drip leg or sediment trap is designed specifically to collect condensate and sediment that might accumulate in a gas piping system. The presence of moisture and particulates can be detrimental to the safe and efficient operation of gas appliances. By having a drip leg, any liquid accumulated can settle at the bottom of the trap, allowing it to be easily drained away. This protects the integrity of the gas system and ensures that appliances receive a clean, unobstructed flow of gas, thus maintaining efficiency and safety.

The functionality of a drip leg is crucial in preventing issues such as blockages or corrosion caused by sediment build-up, which could lead to malfunctions or hazardous situations. Consequently, the correct understanding of a drip leg's role emphasizes the importance of maintaining a clean and efficient gas piping system for both safety and operational performance.
