Question: 1 / 400

What is a potential consequence of not sealing gas piping passing through exterior walls?

Increased pressure in the system

Risk of gas leaks

Entry of moisture and pests

Sealing gas piping that passes through exterior walls is crucial for maintaining the integrity of the system. When gas piping is not properly sealed, it can create openings that allow moisture as well as pests to enter the protected areas of a building.

The entry of moisture can lead to corrosion and deterioration of the pipeline and surrounding materials. This not only compromises the structural integrity of the gas line but can also contribute to issues such as mold growth and additional water damage within the building. Similarly, pests can find their way through unsealed openings, leading to infestations that could cause further structural and health-related challenges.

By ensuring that these pipes are adequately sealed, one can significantly reduce the risks associated with moisture infiltration and pest intrusion, helping to maintain a safe and healthy environment in residential or commercial settings.
