Is it copper? Then it is water.

Is it cast iron? Then it is gas.

If it is plastic, what color is it? Blue, cold water. Red, hot water. Yellow, gas. Orange, not for you to play with. Clear, white, grey? Fuck that guy who did that.

Some older houses in my area have copper gas lines.

Not cast iron, it's rolled steel but the trade name is black iron pipe. Cast iron is used only in drainage.
