Drip locations should be accessible to permit what actions?

Drip locations in gas piping systems are designed to collect condensate and moisture that may accumulate within the system. These locations need to be readily accessible to facilitate cleaning or emptying. This is essential because if the drip location becomes clogged or is not maintained properly, it can lead to improper drainage, resulting in potential damage to the system or unsafe operating conditions. Regular cleaning helps ensure that the drip legs function effectively, preventing moisture buildup, which could otherwise affect the performance and safety of the entire gas system. This access for cleaning and emptying is critical for ongoing maintenance and to adherently comply with safety standards outlined in the National Fuel Gas Code.
