What is a 'pumper connection' and how is it used in NFPA 13E context?

• A. A device used to measure pressure.
• B. A valve that allows drainage to the sewer.
• C. A connection for fire department pumpers to supply the standpipe/sprinkler system with water.
• D. A decorative hose hanger.

Answer: (C)

A pumper connection is the external interface on a building’s fire protection system that lets a fire department pumper supply water into the standpipe or sprinkler piping. In NFPA 13E, which covers fire protection in existing buildings, these connections are provided so firefighters can quickly augment the building’s water supply when the normal source isn’t enough or pressure is insufficient. The connection is usually located on the outside of the building and presents one or more inlets (often 2.5-inch or 4-inch) arranged so the pumper hoses can be attached. When connected, water from the pumper flows into the standpipe or sprinkler system to feed the entire system. This is specifically for delivering water, not for measuring pressure, draining, or decoration.
