What term describes systems for removing water from sprinkler systems?

• A. Drains
• B. Piping
• C. Valves
• D. Residential Occupancies

Answer: (A)

Drains describe the feature that allows water to be removed from sprinkler piping. They provide a pathway at low points and at test and drain assemblies so water can be drained after discharge or during maintenance, which helps dry the system and prevent issues like freezing or water damage. In low-rise residential sprinkler systems, having proper drains is essential for testing and service because it ensures you can fully remove water from the piping when needed. Piping is simply the network that carries water, valves are devices that control flow, and residential occupancies are a classification of space; none of these describe the mechanism for removing water from the system. So, drains is the term that fits this concept.
