What is the definition of a 'horizontal standpipe' according to A.7.10.1.1.6?

• A. A standpipe that feeds only one hose connection
• B. A standpipe that feeds multiple floors
• C. A standpipe connected to the water main
• D. A standpipe used only for testing

Answer: (A)

A horizontal standpipe is defined as a standpipe that serves a single floor area with one hose connection. This distinguishes it from a vertical standpipe, which provides multiple hose connections across several floors. The key idea is that the horizontal type has only one outlet on the floor it serves, rather than feeding outlets on many floors. It’s not defined by being connected to the water main, nor by being used only for testing.
