Internal Pipe Obstruction Inspection for NYC Buildings

NFPA 25 requires every fire sprinkler system to undergo a mandated internal pipe obstruction inspection every five years to examine the interior of your piping and components. This requirement applies to all buildings with water based fire protection systems and must be performed by a licensed professional. Allstate Sprinkler performs these inspections across New York City, providing full documentation to keep your building compliant with FDNY standards.

Your fire sprinkler system is only as reliable as its last inspection.

Regular service performed to NFPA 25 standards assures you that when the system is needed most, it will function exactly as designed. As a building owner or manager, maintaining this standard is both a legal requirement and a critical responsibility.

Allstate Sprinkler has been performing compliant inspections for NYC buildings since 1972. Our licensed technicians keep detailed records of every visit so you are always prepared for an FDNY review.

Fire sprinkler systems that have not received proper care and maintenance over the years may not function as intended during an emergency. Allstate Sprinkler provides thorough internal sprinkler inspections across the New York City region.

The Purpose of a 5 Year Internal Fire Sprinkler Inspection

This inspection exists to examine your sprinkler piping for potential blockages, including rust, slime, microbiologically influenced corrosion, and other foreign organic or inorganic materials that could prevent water from flowing freely during a fire.

During the inspection, a technician opens the flushing connection at one of the main ends and removes sprinkler heads from a sampling of branch lines. If obstructions are found, a more comprehensive internal investigation is conducted to ensure the system is fully clear and operational.
