How do gas lines look like? - Answers

Gas lines typically appear as thin, metallic pipes that can be either black iron, copper, or flexible plastic tubing, depending on the installation and local codes. They may be installed above ground or buried underground, often running from a gas meter to various appliances. The lines are usually connected with fittings and valves, and they may be marked with warning signs indicating the presence of gas. In residential settings, gas lines are usually painted yellow for visibility and safety.
