S13 STANDPIPE TEST 2026 – EXAM QUESTIONS & VERIFIED ANSWERS
QUESTION 1
What is the primary purpose of a standpipe system in a building?
A) To supply water for domestic use in high-rise buildings
B) To provide a means of fire suppression by supplying water to hose connections on
each floor
C) To regulate water pressure throughout a building's plumbing system
D) To store emergency water reserves for building occupants
E) To connect the building's drainage system to the municipal water supply
CORRECT ANSWER: B) To provide a means of fire suppression by supplying
water to hose connections on each floor
RATIONALE: A standpipe system is specifically designed as a fixed fire protection
system. It consists of a system of pipes that supply water to hose connections (outlets)
located throughout a building, primarily on each floor level. This allows firefighters or
building occupants to connect hoses and apply water to a fire without having to carry
hose lines up stairwells from outside the building. The system is not designed for
domestic water supply, pressure regulation, drainage, or water storage for occupants.
QUESTION 2
Which class of standpipe system is designed for use by trained firefighters ONLY?
A) Class I
B) Class II
C) Class III
D) Class IV
E) Class V
, CORRECT ANSWER: A) Class I
RATIONALE: Class I standpipe systems are equipped with 2½-inch hose connections
and are intended exclusively for use by fire department personnel and those trained in
handling heavy fire streams. These larger connections allow firefighters to connect their
own hoses and equipment. Class II systems are for occupant use with 1½-inch hose
stations, and Class III systems combine both types for use by both occupants and
firefighters.
QUESTION 3
What is the minimum residual pressure required at the hydraulically most remote 2½-
inch hose connection in a Class I standpipe system?
A) 50 psi
B) 75 psi
C) 100 psi
D) 125 psi
E) 150 psi
CORRECT ANSWER: C) 100 psi
RATIONALE: NFPA 14 (Standard for the Installation of Standpipe and Hose Systems)
requires a minimum residual pressure of 100 psi at the hydraulically most remote 2½-
inch hose connection for Class I and Class III standpipe systems. This pressure
ensures that firefighters have adequate water flow and pressure to effectively combat
fires on upper floors, even at the most challenging hydraulic point in the system.
QUESTION 4
A Class II standpipe system is primarily intended for use by:
A) Fire department personnel only
B) Building maintenance staff only
C) Building occupants with limited training
D) Emergency medical personnel
E) Security personnel only
, CORRECT ANSWER: C) Building occupants with limited training
RATIONALE: Class II standpipe systems are designed specifically for use by building
occupants who may have limited firefighting training. These systems feature 1½-inch
hose stations pre-connected with hose, allowing occupants to begin fire suppression
efforts before the fire department arrives. The smaller hose size and pre-connected
configuration make the system manageable for untrained individuals. The hose cabinets
are typically located in corridors and common areas for easy access.
QUESTION 5
What does NFPA 14 govern?
A) Sprinkler system installation standards
B) Fire alarm system requirements
C) Installation of standpipe and hose systems
D) Portable fire extinguisher standards
E) Emergency evacuation procedures
CORRECT ANSWER: C) Installation of standpipe and hose systems
RATIONALE: NFPA 14 is the National Fire Protection Association standard that
specifically governs the installation, maintenance, and use of standpipe and hose
systems. It provides minimum requirements for system design, components, water
supply, hydraulic calculations, and testing. Other NFPA standards govern different
systems: NFPA 13 covers sprinklers, NFPA 72 covers fire alarms, and NFPA 10 covers
portable extinguishers.
QUESTION 6
What is the maximum pressure allowed at any 2½-inch hose connection in a standpipe
system under NFPA 14?
A) 100 psi
B) 150 psi
C) 175 psi
D) 200 psi
, E) 250 psi
CORRECT ANSWER: C) 175 psi
RATIONALE: NFPA 14 limits the maximum pressure at any 2½-inch hose connection to
175 psi. Pressures above this threshold can make the hose dangerously difficult to
control, posing a safety risk to firefighters. Where system pressures exceed this limit,
pressure-reducing valves (PRVs) must be installed at the hose connections to reduce
outlet pressure to safe operating levels while maintaining adequate flow.
QUESTION 7
Which type of standpipe system maintains water in the pipes at all times under
pressure?
A) Dry standpipe system
B) Semi-dry standpipe system
C) Wet standpipe system
D) Manual standpipe system
E) Combination standpipe system
CORRECT ANSWER: C) Wet standpipe system
RATIONALE: A wet standpipe system keeps the entire piping network filled with water
under pressure at all times, connected to a reliable water supply. This means water is
immediately available the moment a hose valve is opened, providing the fastest
response time. Wet systems are preferred in heated buildings where there is no risk of
freezing. Dry systems contain pressurized air or nitrogen instead of water, which is
released when a valve is opened and water fills the pipes.
QUESTION 8
What is the minimum flow rate required for the first standpipe in a Class I system per
NFPA 14?
A) 100 gpm
B) 250 gpm
C) 500 gpm
