There is disclosed an apparatus and method for visual identification of valves in multi valve distribution and transmission systems, and particularly for municipal utility infrastructures such as mainline, connection, drain, pressure district, pressure regulating and pressure sustaining valves. In an embodiment, color coded valve box inserts are made to specifications, inserted and secured into place at the opening of multiple valve boxes to easily and accurately identify the different types or sizes of valves. Each color represents a different type or size of valve, as established by the municipality. A color coding chart identifying the different types or sizes of valves may be placed at each point of access to the valves to assist in identification of the different types of valves.
