What is the purpose of the aboveground portion of a sprinkler system?

• A. The aboveground portion includes a network of specially sized or hydraulically designed piping installed in a building, to which sprinklers are connected.
• B. It serves only as a decorative conduit with no sprinkler connections.
• C. It stores extra water in a building's storage room.
• D. It houses the main power supply for the system.

Answer: (A)

The aboveground portion of a sprinkler system is the piping inside the building that carries water to the sprinklers. Its purpose is to be specially sized and hydraulically designed so water can reach each sprinkler head with the right pressure when the system is activated, and to provide a connected network to which all sprinklers are attached. This part is active in delivering water, not decorative, not for storage, and not a power housing. The other choices describe functions that aren’t about delivering water to sprinklers: decoration, storage of extra water, or housing electrical power.
