What are the signs that I have Microbiologically Influenced Corrosion (MIC) or other types of corrosion?
There are many signs of Microbiologically Influences Corrosion (MIC) including pin hole leaks, fire sprinkler system water that is black in color and/or smells like rotten eggs, and water that stains the concrete with rust during flow tests. Any obstructions on the system’s pipe wall, including tubercles and/or mineral deposits are also key indicators of Microbiologically Influenced Corrosion (MIC) in a fire sprinkler system.
