When can you use a PVC "waste and overflow" on a bathtub in an apartment building?

Using a PVC "waste and overflow" on a bathtub in an apartment building is permissible because PVC pipe is commonly approved for use in plumbing systems, especially where drainage and waste conveyance are concerned. The materials and design of PVC pipes provide effective resistance to corrosion, deterioration, and chemicals found in wastewater, which makes them suitable for this purpose.

In apartment buildings, ensuring proper drainage is critical to maintaining plumbing performance and preventing leaks or water damage. The acceptance of PVC for waste and overflow applications is often based on adherence to local plumbing codes, which recognize the material's durability and performance characteristics.

Permitting conditions can vary by jurisdiction, and while the other options reflect instances where additional approvals might be needed or where specific codes may prohibit the use of PVC, the general consensus within many plumbing codes allows for its use provided it meets the necessary standards and regulations.
