Understanding NFPA 25

Last updated 5 years ago

Fire sprinkler systems are the first line of defense against fire devastation in your office building, warehouse, or retail space. Because of this, it’s crucial to have your sprinklers properly inspected by a licensed Master Fire Sprinkler Piping Contractor. Here’s a look at some of the most important details of the National Fire Protection Agency’s (NFPA) provisions for fire sprinkler inspections, known as NFPA 25. 

Complying With NFPA 25

NFPA 25 establishes a national standard for the “inspection, testing, and maintenance of water-based fire protection systems.” This inspection and testing code is enforced nationally throughout most of the country, and is the basis for code enforcement in the NYC area and the State of New York. NFPA 25 includes a number of specific tests and inspections that property owners must have conducted on a regular basis. The frequency and thoroughness of each test and inspection varies, so it is important to hire a reputable fire sprinkler contractor to ensure your safety and to make sure you complying with the law.  

Flow Tests

Some of the most important NFPA 25 inspection and testing codes deal with the strength of water flow. In an NFPA 25 inspection, your fire sprinkler contractor will check the static and flowing water pressure in your sprinkler system to ensure proper readings. An improper reading could be the result of an obstruction or leak.  This test also verifies that the alarm signal is functioning properly in the event of a fire.

Additional NFPA25 Tests

NFPA 25 also requires that owners have their fire sprinkler hardware inspected. Every year, control valves should be tested through their full range to ensure proper operation. Dry pipe valves must be tested annually when partially open and every three years when fully open. Sprinklers should be tested every 50 years to make sure that they would still operate properly in a fire emergency.

Keeping up with various NFPA 25 tests and inspections is vital to the systems performance in the event of a fire. That’s why hiring a trusted commercial fire sprinkler repair and inspection service is so important.
