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

Using a PVC "waste and overflow" system in a bathtub is permissible under certain conditions, primarily due to its characteristics and properties. PVC piping is lightweight, resistant to corrosion, and has good chemical resistance, which makes it a practical choice for drainage systems in various plumbing applications, including bathtubs.

In many jurisdictions, PVC can be used without restrictions as long as it meets local plumbing code requirements and the manufacturer's specifications. This flexibility often applies to apartment buildings as well, provided that the installation conforms to the local building and plumbing codes.

While there might be specific circumstances or local amendments to the code that could affect this generalization, the use of PVC in a waste and overflow configuration is widely accepted, especially if the installation adheres to guidelines and standards designed to ensure safety and function. It’s always advisable to check local codes or regulations to confirm allowable materials in residential plumbing systems.
