What is required for pipes located in freezing areas?

• A. No insulation required for any pipes.
• B. Insulation needed for pipes in freezing areas.
• C. Only for outdoor pipes.
• D. Insulation required only for sprinklers.

Answer: (B)

Pipes in freezing areas must be insulated to prevent the water inside from freezing. When water freezes, it can block flow or crack pipes, which would compromise the sprinkler system’s operation. Insulation helps keep the water temperature above freezing, protecting the system in unheated or exposed spaces such as attics, crawl spaces, garages, or exterior runs. While other measures like heat tracing or enclosure can be used in some cases, insulation is the required baseline for piping located in freezing areas.
