Q. Can you use PVC pipe for gas?

Answer

Is it realistic from a chemical compatibility standpoint? Yes. Can gas travel through it to the heater? Yes. What do you think? Does it adhere to the regulations? No! The pliability of PVC is limited. Plastics, including PVC, are not well suited for storing combustible liquids like gasoline or kerosene. PVC and other polymers are susceptible to deformation in high-temperature conditions, which can also cause them to break or leak. As time passes, and especially after prolonged exposure to the UV rays of the sun, it becomes more brittle. Shifting ground, a single hit from a garden tool, child's toy, or falling item might fracture it, which can subsequently result in a gas leak. Shifting ground can also cause a gas leak.
