it means Caribbean Examination Council (CXC)
A CXC plumbing connection refers to a type of fitting used in plumbing systems, specifically a copper-to-copper connection. The term "CXC" denotes a connection where the first "C" stands for "copper," the second "C" also stands for "copper," and the "X" indicates that it is a female connection, typically designed to join two copper pipes using soldering or compression methods. This connection is commonly used for water supply lines and ensures a secure and leak-free joint.
Cxc = c + (c-x) = 100+ (100-10) = 190
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.
This depends to what exactly you are refering too. However it could be, close coupled for a toilet unit and cxc is code for compression fittings.
C = 100 and XC = 10 less than 100, which is 90, so CXC = 190.
In plumbing terms, the three sides of a triangle are often referred to as the "sides," "base," and "height." These terms can help in understanding the geometry involved in various plumbing installations, particularly when calculating areas for fittings or determining flow paths. While not unique to plumbing, these terms are applicable in design and layout discussions.
In plumbing terms, "IPS" stands for "Iron Pipe Size," which is a standardized system used to describe the dimensions of pipes and fittings. It indicates the nominal pipe diameter and is used primarily for specifying the size of pipes in various materials, including metal and plastic. IPS measurements are crucial for ensuring compatibility and proper fitting in plumbing installations.

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.
There is no such thing as a distinction in CXC...look it up!
