Product Description
Get the latest edition to help ensure the integrity of critical water-based fire protection systems, minimize hazards, and help protect lives and property. The updated and expanded NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, is the most current and complete document covering inspection, testing, and maintenance of water-based fire protection systems. NFPA 25 is incorporated by reference in many U.S. states and offers comprehensive requirements for helping to ensure that these fire protection systems are ready to respond in the event of an emergency.
The 2026 edition features several important updates. These include:
- New requirement for sprinklers that have been installed in dwelling units for over 50 years to be replaced with new fast-response sprinklers or meet a thermal sensitivity test.
- Modifications have been made to permissible antifreeze mixtures.
- New ITM requirements have been added to Chapter 13.
- Guidelines added on when sprinklers should be replaced that have been exposed to a fire event.

FAQ For NFPA 25
1. Is the 2026 edition legally required in my state yet?
Answer: Not necessarily. While NFPA 25 is the national standard, it only becomes law once it is adopted by your local or state Authority Having Jurisdiction (AHJ). Many jurisdictions lag behind by a few years. However, even if your state is still on the 2020 or 2023 version, buying the 2026 edition is considered "best practice" and is often used by insurance companies to determine premiums and liability.
2. Can I use this book for residential properties?
Answer: Yes and no. NFPA 25 covers most water-based systems, but there is a distinction:
-
NFPA 25 is for multi-family residential (like apartments), commercial, and industrial systems.
-
NFPA 13D systems (one- and two-family dwellings) are generally exempt from the rigorous ITM requirements of NFPA 25.
-
Note: The 2026 edition has new specific rules for sprinklers in dwelling units that have been installed for over 50 years, which is a major reason for property managers to upgrade to this edition.
3. Does this book tell me how to install a system?
Answer: No. This is a common misconception.
-
NFPA 13 is the standard for Installation.
-
NFPA 25 is strictly for Maintenance. If you are building a new facility, you need NFPA 13. If you are managing an existing building and need to pass an annual fire marshal inspection, you need NFPA 25.
4. Why should I buy the 2026 edition instead of just using the 2023 version?
Answer: Beyond staying current with the law, the 2026 edition contains critical safety updates that can save money:
-
Antifreeze: It provides the latest permissible mixtures, preventing you from using outdated (and potentially flammable) solutions.
-
Fire Exposure: It adds new guidelines on when to replace sprinklers exposed to fire, preventing unnecessary total-system replacements.
-
Chapter 13: The expanded ITM requirements for valves and components help prevent "surprise" system failures that lead to expensive emergency repairs.
5. Does the book include the forms/checklists I need for inspections?
Answer: While the book provides the requirements for what must be inspected (the "what" and "when"), it does not typically include "fill-in-the-blank" logbooks. However, the NFPA 25 Handbook (a separate, more expensive version) often includes expanded explanations, color photos, and supplemental forms that make it much easier for a buyer to implement a maintenance program.
