Final answer:
For wastewater from swimming pools, PVC or CPVC pipes are commonly used due to their chemical resistance and durability. Copper and brass pipes are less common for this purpose.
Step-by-step explanation:
Pipes carrying wastewater from swimming or wading pools, which include pool drainage, backwash from filters, and discharge from pumps, are typically made from certain materials that resist the potentially corrosive nature of chemically treated pool water. While the question doesn't provide a specific code reference that would dictate the pipe material, it's prompt implies a selection of material.
PVC pipes and CPVC pipes are commonly used for this purpose due to their durability and chemical resistance. Copper pipes and brass pipes are less commonly used for wastewater or chemically treated water due to their potential to corrode over time and the higher cost associated with these materials.
