Pipe materials that are least susceptible to corrosion by acids formed by gases generated in sewers are

• A. Acp
• B. Cip
• C. Vcp
• D. Rcp

Answer: (C)

Sewer gases can form sulfuric acid, which attacks many cementitious and metal pipe materials. Plastics, like vinyl chloride pipes, are highly resistant to this kind of chemical attack because they’re non-porous and chemically stable in acidic environments. Therefore, vinyl chloride pipe is least susceptible to corrosion from the acids formed by sewer gases. Asbestos cement pipe, cast iron pipe, and reinforced concrete pipe all have cementitious or metallic components that are more vulnerable to sulfuric acid attack, so they corrode more readily in sewer gas conditions.
