Do Fire Sprinkler Systems Need to Be Inspected? Explained for New Brunswick and Edison

Fire sprinkler systems must be inspected regularly to stay compliant with NFPA 25, protect property, and ensure that all components activate correctly during a fire emergency. If you own or manage a property in New Brunswick or Edison, understanding inspection requirements is essential for safety and legal compliance.

Below is a complete guide based on national standards and New Jersey best practices.

Why Fire Sprinkler Systems Must Be Inspected

Fire sprinkler inspections are required under
NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems.
This national standard outlines how often each component of the system must be inspected, tested, and maintained.

The State of New Jersey also adopts NFPA 25 through its
Uniform Fire Code, which means property owners are legally responsible for ensuring their systems are maintained.

Regular inspections help identify issues such as corrosion, blocked pipes, closed control valves, damaged sprinkler heads, or low water pressure.

How Often Fire Sprinkler Systems Need to Be Inspected

NFPA 25 organizes inspection requirements into four intervals:

1. Weekly

Basic visual checks of system valves and gauges.
Details appear in the NFPA’s guidance on valve supervision requirements.

2. Monthly

Verification that water pressure, control valves, and alarm components are in normal operating condition.

3. Quarterly

Testing of water flow switches, supervisory signal devices, and fire pump alarms.

4. Annual

A licensed contractor performs a full system evaluation, including sprinkler heads, pipes, hangers, water flow, and system hydraulics.

5. Every 5 Years

A more in-depth internal pipe assessment, required by
NFPA 25 Chapter 14.
This helps detect corrosion, microbial growth, and obstructions in underground or hard-to-access piping.

These intervals ensure the system stays operational and code compliant.

Who Is Responsible for Inspections?

According to the U.S. Occupational Safety and Health Administration and NFPA 25, the property owner (or the owner’s designated representative) is always responsible for making sure inspections, testing, and maintenance are performed on schedule.

This applies to:

• Apartment buildings

• Office buildings

• Retail centers

• Industrial facilities

• HOA communities

• Government properties

If the system fails during a fire and inspections were skipped, the owner can be held liable.

What Fire Sprinkler Inspections Include

A full inspection generally includes:

• Checking sprinkler heads for corrosion, paint, dust, or physical damage

• Verifying pressure gauge readings

• Inspecting control valves

• Confirming alarm and supervisory signals function correctly

• Testing main drains and water flow

• Examining visible piping

• Assessing underground piping condition

• Ensuring compliance with New Jersey’s fire safety requirements via the
  NJ Division of Fire Safety

These steps help keep both occupants and property safe.
