What is a common cause of gas leaks in piping systems?

Improper joints or fittings are a common cause of gas leaks in piping systems because they can create gaps in the connections between pipes, allowing gas to escape. When joints are not installed correctly or when fittings are not compatible with the materials used, it can lead to insufficient sealing. Over time, vibration from the plumbing system, temperature changes, or the stresses of installation can worsen these issues, increasing the likelihood of a leak.

Effective installation practices, such as using appropriate types of sealants, ensuring proper alignment, and tightening joints to the manufacturer's specifications, are essential in preventing gas leaks associated with fittings and joints. This emphasizes the importance of a skilled installation by trained professionals to maintain system integrity and safety.
