How many extra sprinkler heads should be kept on hand?

• A. 4
• B. 6
• C. 8
• D. 10

Answer: (B)

Having spare sprinkler heads on hand is about being ready to replace heads quickly during maintenance or after damage, so downtime isn’t slowed by waiting for replacements. They should be the same type and temperature rating as the installed heads and kept in protective packaging for easy access near the system. Six spare heads provide a practical balance for a typical facility, giving replacements for several heads during inspections or testing without tying up excessive capital. Having fewer than six could delay repairs, while more than six is often unnecessary for a standard setup.
