What is the required temperature range to maintain for sprinkler piping?

• A. 32°F to 100°F.
• B. 40°F to 120°F.
• C. 60°F to 120°F.
• D. 50°F to 140°F.

Answer: (B)

Maintaining an appropriate ambient temperature around sprinkler piping is essential to keep the system reliable. If the space falls below the minimum, water in the pipes can freeze, leading to pipe damage or blocked sprinklers. If the space gets too hot, the materials used in residential sprinkler systems—like certain plastic piping and elastomeric seals—can degrade or lose performance. The required range for low-rise residential systems is 40°F to 120°F, which prevents freezing while avoiding temperatures that could harm components. So the correct range is 40°F to 120°F. Ranges that are too cold risk freezing; ranges that are too hot can degrade materials or compromise operation.
