NFPA 25 Inspection

NFPA 25 requires an internal inspection of fire sprinkler system piping in NYC every five years. This is to be conducted to inspect for the “presence of foreign organic and inorganic material.” Foreign materials can cause obstructions to pipe and sprinklers.

Three levels of inspection

Internal Pipe Inspection

This requires the opening of a flushing connection at the end of one main and removal of one sprinkler head near the end of a branch line. These openings are to be inspected for the “presence of foreign organic and inorganic material.”

Internal Pipe Examination

For ‘at-risk’ systems, NFPA 25 lists conditions in which this type of internal pipe exam is to be performed. This inspection requires internal pipe examinations at the following four points of a fire sprinkler system:

• System valve
• Riser
• Cross main
• Branch line

Obstruction Investigation

This is to be performed if foreign organic or inorganic material is found during an internal pipe inspection. NFPA 25 provides the requirements to conduct obstruction investigations.
