Question 1

According to FDNY regulations, how often must control valves on a standpipe system be visually inspected?

Accepted Answer

Weekly

Answer

Control valves must be visually inspected on a weekly basis to ensure they are in the normal position, accessible, and not leaking. This frequent check is critical for ensuring the system's readiness.

Question 2

A full flow test of the fire pump must be conducted at what frequency?

Accepted Answer

Annually

Answer

An annual full flow test is required for fire pumps to verify that the pump and its driver are capable of supplying the required rated flow and pressure. This test ensures the pump will perform as designed during a fire event.

Question 3

How often is a hydrostatic test required for a standpipe system?

Accepted Answer

Every 5 years

Answer

NFPA 25 and FDNY rules require a full hydrostatic test of the standpipe system every 5 years. This test subjects the piping to high pressure to ensure there are no leaks or weaknesses that could cause a failure under operational pressure.

Question 4

The main drain test for a standpipe system should be performed at what minimum frequency?

Accepted Answer

Annually

Answer

The main drain test is conducted annually to check the condition of the water supply. It involves recording the static and residual pressures to detect any significant changes that might indicate a problem like a partially closed valve or obstruction in the supply line.

Question 5

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

Accepted Answer

Weekly

Answer

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.
