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.

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.
A vacuum breaker is a mechnical device used to avoid backflow or a negative pressure in a plumbing system. It typically consists of an air valve with a spring holding it closed. When the pressure within the system is positive, the valve remains closed. When the pressure is negative (less than atmospheric), the negative pressure overcomes the force of the spring holding the valve closed and the it opens, typically allowing normal atmospheric air to enter the system, thereby eliminating the negative pressure. Otherwise, the negative pressure might cause backflow of the plumbing system. ...
An baromtric loop as regards to plumbing is an 1 way backflow preventer,meaning it prevents backflow from the standpoint of an backsiphonage or an vacuum condition.It is a piping arrangement that consist of an vertical pipe of at least 33.7 feet if I remember correctly where in a perfect vaccum it cant siphon the contents on the supply side past the top of the loop due to the physics of it being impossible to create an perfect vacuum
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
In plumbing, by using a device known as a backflow preventer. It only permits water to move in one direction.

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.
An ORG, expanded, is an Overflow Relief Gully
A backflow is a flow of a liquid in a direction opposite to that which is intended.

The semilunar valves prevent backflow into the ventricles. The pulmonary semilunar valve prevents backflow in the right ventricle, and the aortic semilunar valve prevents backflow of blood in the left ventricle.
