An anodeless riser is permitted on which pipe materials?

• A. PE Piping only
• B. Copper Piping only
• C. Black Iron only
• D. PE Piping, Copper, or Black Iron

Answer: (D)

An anodeless riser is designed to connect LP-gas piping to the tank without needing a separate sacrificial anode, and it is approved for use with multiple pipe materials. For PE piping, the nonmetallic nature means corrosion concerns aren’t an issue, so a properly rated anodeless riser provides a secure, leak-tight connection at the tank. For copper piping, the riser can be used with the appropriate dielectric and sealing fittings to prevent galvanic issues and maintain a reliable gas path. For black iron (steel) piping, the riser is compatible when installed with the correct fittings and bonding, helping control corrosion risks without requiring an external anode in typical underground setups. So the best choice includes all three materials: PE Piping, Copper, or Black Iron.
