Water-based fire sprinkler protection systems comprise the bulk of commercial and residential installations. Properly inspecting, testing, and maintaining these complex systems requires close attention to mechanical details and various important provisions.
The new 2014 NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems offers comprehensive guidance on maintaining suppression systems for optimum performance. Effective use of NFPA 25 reduces risk of death by 80% and average property loss by nearly 70%. In fact, 2013 NFPA 13 requires that installers leave a copy of NFPA 25 with property owners so that inspectors, building owners, and facility managers can maximize protection.
Inspection, testing, and maintenance regimes covered by NFPA 25 include evaluation techniques such as:
- Fire sprinkler inspections
- Valve status tests
- Internal piping assessments
- Fire pump operating tests
- Fire pump flow tests
- Forward-flow tests for back-flow preventers
- Risk assessment and performance-based testing programs
- Preparing preplanned impairment reports, hydrant flushing, and testing
Learn about the latest provisions in the new 2014 NFPA 25:
- Updated fire pump operating test-frequency rules
- New fuel-supply testing procedures for diesel-driven fire pumps
- Modified definition of "sprinkler system" for consistency with NFPA 13
- Clarification about inspecting the insides of sprinkler pipes
- An expanded scope that includes water-mist systems
- The addition of valve status testing to ensure water is reaching the sprinkler system
Ongoing water-based fire protection system maintenance is far less costly than having to replace entire systems. And ensuring function and performance of sprinkler systems is especially important for protection of life and property.
To stay compliant with NFPA 25 and meet the highest national standards of fire and electrical safety, order your copy today. (Softbound, 136 pp., 2014)

ITM questions? The 2014 NFPA 25 Handbook has the answers you need to conduct efficient safety checks and avoid sprinkler failures.
Because errors or oversights in sprinkler upkeep could result in fire tragedies and fire loss, it's vital not only to work with the latest ITM requirements, but also to make sure you apply them correctly. And that's exactly what the comprehensive 2014 Water-Based Fire Protection Systems Handbook is designed to do.
This essential NFPA 25 companion strengthens your understanding of the intent behind rules and the function of the systems and components covered in the Standard so you can improve sprinkler reliability and increase equipment service life.
- The complete 2014 NFPA 25: Inspection, Testing, and Maintenance of Water-Based Fire Protection Systemstext is included for convenient reference and enhanced by explanations and practical application advice.
- Case studies provide examples of real-world sprinkler experience.
- 100+ full-color photos, charts, illustrations, and other visuals clarify concepts.
- Sample inspection, testing, and maintenance forms help in implementing your own procedures.
- Updated FAQs highlight key topics.
NEW 2014 features include:
- Step-by-step testing procedures provide an example of a correct and proven way to conduct a test.
- ITM vs Design Evaluation feature presents specific examples and helps users determine whether or not something is within the scope of NFPA 25 (ITM) or out of scope (Design Evaluation).
- Four new supplements expand your expertise -- Fire Pump Flow Test Analysis, Role of the AHJ, Inspection Roles and Responsibilities (Table), and Fire Pump Field Data Collection and Analysis.
Anyone who works with sprinklers -- from sprinkler contractors, service contract providers, facility managers, and building owners to engineers and designers, consultants, AHJs, insurance representatives and NFPA 13: Installation of Sprinkler System users -- needs the 2014 NFPA 25 Handbook to ensure water-based systems are up-to-code and ready to protect lives and property.
