If you notice your fire sprinkler system pipes turning an orangey red, they are corroded. Corrosion is deterioration caused by a chemical reaction. It’s a common problem with wet and dry fire sprinkler systems. But you can protect your equipment by following these tips for preventing corrosion in a fire sprinkler system.

One of the best ways to ensure the safety and efficacy of your fire sprinkler system is to meet testing and inspection requirements determined by the National Fire Protection Association (NFPA). The NFPA determines the frequency of inspections, testing, and maintenance of fire sprinkler system parts.

Sprinkler systems combine elements like oxygen, water, and metal, which makes corrosion a common problem. The presence of rust is an indication that you need to replace your fire sprinkler system. Following the maintenance schedule helps to prevent corrosion from becoming a problem.

The next tip for preventing corrosion is to use corrosion-resistant materials in your fire sprinkler system. While materials other than metal can corrode, the use of corrosion-resistant materials drastically reduce corrosion.

Chlorinated polyvinyl chloride (CPVC) is one popular corrosion-resistant material for fire sprinkler systems. CPVC is faster to install than metallic systems, has a 50-year life expectancy, and resists corrosion and deposits that could cause water flow blockages. The NFPA accepts this material to be used in single- and multi-family housing and other occupancies designated as “light hazards.”

Even with regular maintenance, if you notice signs of possible corrosion, you should investigate further to ensure the stability of your system. If you notice plugged sprinklers, leaks, foreign materials in the fire pumps or check valves, get a fire protection specialist to check out your system.

Corrosion can cause obstruction in your pipes and block the flow of fire-extinguishing materials. Corrosion can also cause your system to shut down temporary or completely.
