If you have slip compression fittings (brass/PVC) on your bath tub over flow and drain then you need to have a adapter PVC glue to compression before the trap running vertical and you will also need a access to inspect the compression fittings by most codes. I use glued fittings on all my tub drain and overflows because its the best kind of connection and you don't need access to it.

You are mistaken, - Many PVC pipes are marked DWV ( not DMV ) This is an acronym for Drain, Waste, Vent. -These pipes are not suitable for high pressure usage and this marking means they are only intended for light use.
Pvc pipes are cheaper. They are easier to join. They last longer.
PVC stands for polyvinyl chloride, which is what PVC pipes are made of.
PVC pipe fittings are used to connect and join different sections of PVC pipes together. They provide a secure and leak-proof connection, allowing for the smooth flow of liquids or gases through the pipes. These fittings come in various shapes and sizes, such as elbows, tees, couplings, and adapters, and they can be used for a wide range of applications, including plumbing, irrigation, and construction.
Because modern PVC and PEX pipes are much more efficient and easier to work with.
These days PVC pipes are faster and easier to fit and in many ways more efficient than cast iron.
PVC pipes are less expensive and easier to repair. Metal pipes are more expensive and more difficult to repair.
