The National Fire Protection Association and the FDNY have imposed strict regulations for NYC buildings, known as NFPA25. However, these regulations can be challenging to understand; as a result, violations are frequently handed out.

In order to meet the required standard for fire protection systems, various inspections are performed monthly, quarterly, annually, and every 5 years and range from visual inspections of gauges to testing sprinkler control valves and water flow, to testing for obstructions.

How often should fire sprinkler systems be inspected and tested?



Inspections, Testing, and Maintenance are performed in accordance with NFPA25

Visual Inspections of Main Components

Every year there should be a complete test of your fire sprinkler system. Our technicians will physically check every element of your system, from water flow and fire pump tests right through to alarm tests and trip tests of dry pipe, deluge, and pre-action valves.

This is where inspections will move on to looking at the pipework and fittings, hangar/seismic bracing, signage, and the sprinklers themselves. Annual tests and inspections include the monthly visual inspection, semi-annual inspections, and quarterly inspections in addition to:

  • Hangers and seismic bracing
  • Check piping for ( corrosion, leaking, alignment, and free of external loading) 
  • Check sprinkler heads ( leakage, corrosion, foreign materials, paint, physical damage, orientation, obstructions,)
  • Glass bulbs are full of liquid
  • 6 spare sprinklers are located in the sprinkler room
  • Wrench is available

*Before the temperature drops, we assess the risk of winter hazards:

  • The building is secure and pipes are not exposed
  • Adequate heat is provided to the system
  • Temperatures of 40 degrees F or higher can be maintained

Annual Flow Tests

If your building has more than 32 sprinkler heads you must have a Flow Test performed and reported (to the FDNY) annually by a Fire Suppression Contractor or LMP. This test ensures that if your system should become activated, there will be adequate water pressure to the uppermost section of the sprinkler system to provide fire protection. The minimum water pressure must be 15 PSI at the test station. 

*The Fire Department will notify you by mail that you must schedule a test. 

Additional Annual Tests...

MD Test WM #1 & 2

Fire Pump Full Test

Dry Pipe Valve Trip Test ( with and without FDNY)

Standpipe Flow & Hydrostatic Tests

Sprinkler Hydrostatic Tests

FDNY 5-Year Flow Test

Once every five years, the FDNY must witness your flow test. The Fire Department will notify you by mail that you must schedule a test. Please send us a copy of the notification so we can help you schedule your test with the FDNY.

In order to conduct this test, the building must have an Inspector Test Valve installed on your sprinkler system. This allows the Fire Department to measure the water pressure in the sprinkler system. 

  • It must be located on the uppermost floor of the building, in a public hallway, directly after the sprinkler head furthest from the building’s entrance.
  • It is identifiable by pressure gauges, a hose valve, and a small white sign stating, "Inspector’s Test Valve". 
  • This test requires a small bucket and a hose.

Violations and Local Law

Fire protection is an essential element in your overall safety and security plan. Making sure you have the right fire sprinkler system, as well as choosing a reliable fire protection company to help with required inspections, will ensure your property remains safe.

There are myriad local laws and building codes that apply to fire sprinkler systems, ranging from correctly painting fire sprinkler piping systems, and control valve handles to conducting regular tests, to maintaining careful records of the fire sprinkler system inspection testing, and maintenance.


During the inspections, we check for damages or alterations to your sprinkler system and confirm whether or not it is operating properly and that all components are undamaged. 

Each month we email you a copy of the inspection, photos of your system, and easy-to-understand proposals detailing how to fix any issues if we encounter them. Your information is kept on file and your account can be accessed anytime via our online portal.
