To allow water to flow in only one direction. (Correct answer)
To regulate water pressure.
To shut off the water supply for maintenance.
To connect fire hoses.

Correct answer: To allow water to flow in only one direction.

A check valve is a one-way valve that prevents the backflow of water. In a standpipe system, it ensures that water from the Fire Department Connection (FDC) flows into the system and not back out, and it prevents water from the primary supply from flowing out the FDC.

Question 11: In a building with a dry standpipe system, how often must the air pressure and water pressure gauges be checked?

Monthly
Weekly (Correct answer)
Daily
Quarterly

Correct answer: Weekly

For dry pipe systems, it is crucial to check the air and water pressure gauges weekly. This ensures that the system has adequate supervisory air pressure to prevent accidental tripping and sufficient water pressure available when needed.

Question 12: According to FDNY regulations, how long must the standpipe system logbook be maintained on the premises?

5 years
1 year
3 years (Correct answer)
For the life of the building

Correct answer: 3 years

FDNY Fire Code requires that all records related to the inspection, testing, and maintenance of the standpipe system, including the logbook, be kept on the premises for a minimum of three years. These records must be readily available for inspection by Fire Department representatives.

Question 13: What is the purpose of a pressure-reducing valve in a standpipe system?

To reduce water flow to specific areas
To ensure that the water pressure is at a safe and manageable level (Correct answer)
To shut off the water supply during maintenance
To increase the pressure in the standpipe system

Correct answer: To ensure that the water pressure is at a safe and manageable level

Pressure-reducing valves (PRVs) are essential in standpipe systems, especially in tall buildings, to regulate and lower excessive water pressure at hose connections. High pressure can make hoses difficult to control and potentially dangerous for firefighters. PRVs ensure the water pressure is within a safe and effective range, allowing for efficient and controlled fire suppression.

Question 14: What is the purpose of a pressure-maintenance (jockey) pump in a standpipe water supply system?

To compensate for minor system leaks and maintain system pressure without starting the main fire pump (Correct answer)
To fill the suction tank automatically
To test standpipe pressure weekly
To boost pressure during active firefighting

Correct answer: To compensate for minor system leaks and maintain system pressure without starting the main fire pump

A jockey (pressure-maintenance) pump is a small pump that cycles on and off to maintain standpipe system pressure, compensating for minor leakage without activating the larger main fire pump.

Question 15: What is a standpipe system primarily designed for?

To store potable water for the building's occupants
To provide water for the building's cooling system
