Anodeless risers are commonly used on plastic gas piping systems in which setting?

• A. Above ground
• B. Inside buildings only
• C. In above-ground outdoor locations
• D. Underground only

Answer: (D)

Anodeless risers are designed for plastic gas piping systems to provide a reliable, corrosion-protected transition where the service line is buried. Because they are built to operate in soil environments and to join underground sections, they’re specified for underground use. The protection and sealing features are intended for burial conditions, so using them above ground, indoors, or in exposed outdoor locations isn’t appropriate and other types of risers or connections are used there. This is why the setting described is underground only.
