Which color band designates reverse osmosis water purification piping that carries raw water?

The color band that designates reverse osmosis water purification piping carrying raw water is black. This color coding system is essential in water and fuel systems maintenance, as it helps identify the type of water and its treatment stage throughout the system.

In many systems, black is commonly used to signify raw or unprocessed water lines, which is critical for appropriate handling and maintenance. Proper identification through color coding reduces the risk of cross-contamination and ensures that the correct procedures are followed when working on or around these lines.

The distinction between colors in piping not only aids technicians and maintenance personnel in quickly identifying the purpose of the piping but also promotes safety and efficiency in maintenance operations. Understanding these standards is vital for effective management of water purification systems.
