Preview the 2022 NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection Handbook

2019 Edition

Editors: Chad R. W. Duffy, Janna E. Shapiro

Expanded and renamed, the Stationary Fire Pumps and Standpipe Systems Handbook addresses NFPA 20 and NFPA 14 requirements for all types of fire pumps and standpipe systems.

Order this practical resource for expert advice on helping to keep fire pumps and standpipe systems in compliance and functioning error-free! Developed by NFPA® and featuring commentary written by leading authorities in the field, the expanded Stationary Fire Pumps and Standpipe Systems Handbook is based on the 2019 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, and the 2016 edition of NFPA 14, Standard for the Installation of Standpipe and Hose Systems.

Access a wealth of information and support in a single source.

The Handbook provides advanced guidance relating to all types of equipment, along with water supply availability and reliability. An exclusive Overview of Fire Pump Configurations includes examples of fire pump arrangements and explains the purpose of the components in each arrangement. The overview also features a full-color diagram that helps designers and engineers understand how multistage, multiport pumps can eliminate the need for pumps in series, potentially saving money.

The Handbook is also organized into the following four parts:

• Part I includes the complete 2019 edition of NFPA 20, plus expert commentary. This edition introduces first-time sections on Pressure Control at the end of Chapter 4, General Requirements; Fire Pump Curve and Analysis at the end of Chapter 6, Centrifugal Pumps; and Electrical Power Supply for Fire Pumps in Chapter 9, Electric Drive for Pumps.

• Part II features the complete 2016 edition of NFPA 14, plus expert commentary.

• Part III: Water Supply Requirements, Water Demand, Hydrants, Tanks, and Piping contains text from selected water supply documents with original supporting explanations and advice. Material includes:
• Section 1 with the full 2019 edition of NFPA 291, Recommended Practice for Fire Flow Testing and Marking of Hydrants, plus commentary
• Section 2 with the full 2019 edition of NFPA 24, Standard for the Installation of Private Fire Service Mains and Their Appurtenances, plus commentary
• Section 3 with Sections 18.4 and 18.5 from the 2018 edition of NFPA 1, Fire Code, plus commentary
• Section 4 with extracts from the 2018 edition of NFPA 22, Standard for Water Tanks for Private Fire Protection, plus commentary

Part IV: Supplements address:

• Considerations When Designing and Selecting a Fire Pump
• Interrelationship of NFPA Standards Pertaining to a Fire Pump Installation, including a full-color, pull-out illustration of a fire pump installation
• Commissioning and Inspection, Testing, and Maintenance Forms for Fire Pumps
• NEC® Article 695, Fire Pumps

Design features make information more accessible.

• Just like in the standards, shading and change symbols tell you where a change has occurred.
• "Ask the AHJ" and FAQs help installers avoid common errors.
• "Design Alerts" call out commentary relevant to design issues.
• Calculation Example feature is separate from commentary.
• "See More" feature includes pointers that help you navigate the Handbook.
• Summary of Technical Changes tables for NFPA 20 and NFPA 14 each provide a brief overview of major code changes from the previous edition to the current edition.

Part I also includes commentary written by leading experts Jim Biggins, John Campbell, Bradford Cronin, John Kovacik, Jennifer McGrath, Gayle Pennel, and Jeffery Roberts.

Part II: Private Water Supplies, Hydrants, Tanks, and Piping contains text from selected water supply documents with original supporting explanations and advice. Material includes:

• Complete texts of the 2016 NFPA 24, Installation of Private Fire Service Mains and Their Appurtenances with all-new commentary and 2016 NFPA 291, Recommended Practice for Fire Flow Testing and Marking of Hydrants

• Sections 18.4 and 18.5 from the 2015 NFPA 1, Fire Code

• Extracts with expert commentary from the 2013 NFPA 22, Water Tanks for Private Fire Protection, the 2014 NFPA 14, Installation of Standpipe and Hose Systems concerning standpipe water supply, and the 2016 NFPA 13, Installation of Sprinkler Systems.

Part III: Supplements includes an all new Fire Pump Design Considerations Supplement, a full-color pull-out schematic explaining the interrelationship of NFPA standards as they relate to pump installations with narrative, updated commissioning forms for fire pumps, Article 695 on power supplies for electric-driven fire pumps extracted from the 2014 NEC Handbook, and technical changes from the 2013 to the 2016 NFPA 20.

New design features make information more accessible.

• Code Update icons indicate a change has occurred.
• "Ask the AHJ" FAQs help installers avoid common errors.
• "Design Alerts" call out commentary relevant to design issues.
• All calculations appear within commentary text.
• Cross-reference icons help you navigate the Handbook.
