Corrosion in firewater sprinkler systems has become a major concern in recent years. The causes are a diverse mixture of water chemistry, materials of construction, and microbiological attack. The expense of the damage to property in the area of system leaks plus the potential for sprinkler failure in an actual fire has raised the need for identifying and preventing this phenomenon. In many cases existing systems must be cleaned of foulants before effective treatment can be applied.
