In corrosive environments, what is required for sprinkler system components?

• A. No special fittings are required in corrosive environments.
• B. Fittings must be acid-coated only.
• C. Special fittings needed in corrosive environments.
• D. Use corrosion-resistant paint on fittings.

Answer: (C)

In corrosive environments, sprinkler system components must use fittings that resist corrosion. Corrosion can quickly degrade standard metal fittings, leading to leaks, reduced water supply, or system failure when it’s needed most. Using fittings that are specifically designed for corrosive conditions—often made from corrosion-resistant materials or with durable protective coatings—helps ensure the system remains functional over time. Relying on paint coatings or coatings alone is not sufficient, because coatings can wear, chip, or degrade, leaving metal vulnerable. The requirement is about employing special fittings appropriate for corrosive conditions, which provides a more reliable and code-compliant approach to preserving system integrity.
