Straight answers for property owners and managers dealing with leaks, discolored water, or a repair quote they aren't sure about.
Ask Corrosolve a QuestionFire sprinkler corrosion raises questions that most repair invoices never answer. The sections below cover the basics of MIC, the symptoms owners and managers notice first, and what a proper diagnosis looks like. For deeper explanations, visit our pages on what MIC is and pinhole leaks.

MIC stands for microbiologically influenced corrosion. It occurs when microbes form colonies, called biofilms, inside sprinkler piping and create a corrosive environment on the metal surface. It is the most intrusive and difficult type of corrosion to resolve.
Oxygen cell corrosion is the most common form and produces rust through contact between steel, oxygen, and water. Cathodic corrosion involves electrochemical reactions, often tied to grounding or dissimilar metals. MIC is driven by bacteria and other microbes feeding in the water and on the pipe.
Contributing factors include pH, material defects, nutrients, temperature, low flow, and oxygen levels. Changes in water chemistry that introduce oxygen and nutrients can also support bacterial growth.
Yes. MIC can lead to premature metal failure in both wet and dry sprinkler and standpipe systems.
Yes. Active MIC infections continue spreading unless they are treated. That is why identifying where an infection is, and how far it has progressed, is central to choosing the right remediation.
Repeat leaks in the same area often point to internal corrosion rather than random failures. Patching each leak treats the symptom, while an assessment looks for the cause.
A pinhole leak is a small perforation in sprinkler piping, commonly caused by localized internal corrosion. Pinhole leaks tend to recur until the underlying corrosion is addressed.
It can indicate corrosion or microbial activity inside the piping, though other causes are possible. Water testing and an internal inspection can determine what is behind it.
Common signs include repeat leaks, dark or foul-smelling water, ceiling or wall staining with no clear source, and findings from an inspection that point to internal pipe conditions.
It can contribute, because internal deposits and rough surfaces can restrict flow. Report any suspected pressure or flow problem to your licensed fire protection contractor promptly, and consider an internal inspection if corrosion is also suspected.
Contact your licensed fire protection contractor, follow your impairment procedures if any part of the system must be shut down, protect people and property, and document the leak. Keep any removed pipe so it can be evaluated.
Not necessarily. MIC is typically localized, so damage is often concentrated in specific sections. An assessment helps define the real scope before you commit to a full replacement.
Usually not. Flushing with fresh water introduces oxygen and nutrients that can revitalize bacteria and speed up corrosion. Testing and a treatment plan are a safer approach.
Yes. A corrosion control program reduces oxygen levels, mitigates MIC, and uses ongoing monitoring and testing to keep water conditions within protective parameters.
Remediation repairs the damage: irreparable piping is replaced, the system is chemically cleaned, and it is treated with a corrosion inhibitor solution. A corrosion control program is the long-term step that maintains protective conditions through treatment, monitoring, and testing.
It includes water quality analysis, internal video inspection with a serpentine borescope, ultrasonic wall thickness testing, an evaluation of the degree of MIC infection, and a defined scope of repairs.

It is a written technical summary of corrosion issues and risk factors, with high-resolution images from inside the piping, documentation of physical evidence, root cause identification, and strategic remediation recommendations.
Yes. Post-assessment support includes coordination meetings with contractors to define the scope of work, consultations with ownership or management, and post-construction verification that completed work aligns with the defined scope.
