In Plumbing, a trap is a U-, S-, or J-shaped pipe located below or within a plumbing fixture. An S-shaped trap is also known as the S-bend invented by Alexander Cummings in 1775 but became known as the U-bend following the introduction of the U-shaped trap by Thomas Crapper in 1880. The new U-bend could not jam, so, unlike the S-bend, it did not need an overflow. The bend is used to prevent sewer gases from entering buildings. In refineryapplications, it also prevents hydrocarbons and other dangerous gases from escaping outside through drains.
The most common of these traps in houses is referred to as a P-trap. It is the addition of a 90 degree fitting on the outlet side of a U-bend, thereby creating a P-like shape. It can also be referred to as a sink trap due to the fact it is installed under most house sinks.
Because of its shape, the trap retains a small amount of water after the fixture's use. This water in the trap creates a seal that prevents sewer gas from passing from the drain pipes back into the occupied space of the building. Essentially all plumbing fixtures includingsinks, bathtubs, and toilets must be equipped with either an internal or external trap.
Because it is a localized low-point in the plumbing, sink traps also tend to capture heavy objects (such as jewelry) that are inadvertently dropped into the sink. Traps also tend to collect hair, sand, and other debris and limit the ultimate size of objects that will pass on into the rest of the plumbing, thereby catching over-sized objects. For all of these reasons, most traps can either be disassembled for cleaning or they provide some sort of cleanout feature.

Yes, copper pipes are used extensively in plumbing.
I am not familiar with that. Do you mean PVC? PVC is a type of plastic pipe. It is very strong and durable, is used a lot for plumbing as it does not rust. It is used with high efficiency HVAC systems. It is light weight. Usually it is white or a gray color.
The word backflow in terms of plumbing refers to an unwanted flow of water in the wrong direction. The risk of a contamination of clean water is prevented by backflow prevention devices.
DRZ is not an acronym that is used in the plumbing industry so it does not stand for anything. DFU in plumbing means drainage fixture unit.
When it comes to a plumbing fitting, description CxC means the fitting is Copper by Copper, or the fitting is used to join two pieces of copper

Brass is commonly used for most plumbing fittings.
I have never seen a stapler used for any plumbing purpose.
Some plastic plumbing applications can be used for other things such as science projects, Halloween costumes, to unclutter one's home, and other creative things.

Yes they had indoor plumbing in World War 2. Some farmers did not have it but nearly everyone in the cities in the US, US and Europe and Some Asian places had indoor plumbing. You asked the right person. My grandfather had a hardware store and plumbing business way back then.
