Where sprinklers are subjected to harsh environments, including corrosive atmospheres and corrosive water supplies, on a five years basis shall be what?

• A. Retested on five-year basis
• B. Replaced
• C. Replaced or tested
• D. Replaced or representative sprinkler samples shall be tested

Answer: (D)

In harsh environments, sprinklers face higher corrosion risk, so maintenance standards call for a five-year check that either replaces those sprinklers or tests a representative sample to gauge condition. This approach is practical and safety-focused: it isn’t required to replace every head every five years, but you must verify the overall condition by testing a properly chosen subset of sprinklers. If the representative tests show acceptable condition, you can continue operation without wholesale replacement; if they reveal deterioration, replacement is warranted. That’s why the correct approach is to replace or test representative sprinkler samples on a five-year basis.
