Resolution: FR-14-NFPA 24-2013Statement: Technical Committee Statement – At the close of the 2013 edition revision

cycle, the Technical Committee (TC) on Private Water Supply Piping Systems noted that the document was incongruent with portions of NFPA 13, NFPA 14, NFPA 20 and other design and installation standards. Furthermore, it was determined that the order that information was presented in the standard was not optimal and could be revised to make the document easier to follow. The TC developed a task group to work on a rewrite of the standard for the 2016edition of the standard. The revisions to chapter 3 addressing the definitions were made in an attempt to better correlate with the other water-based system documents. Specific revisions to the standard are as follows: -Definitions for automatic drain valve and control valve were added. -3.3.5 The term "retardant" was replaced with "retarding" since that is what is used in the standard. -3.3.17.2 The definition was revised to state what the device is as opposed to providing examples of what types of valves can be indicating valves. -3.4 The hydrant definitions were cleaned up to describe the type of hydrant in question, as opposed to describing when and where they would be used.

Public Input No. 56-NFPA 24-2013 [ New Section after 5.1.2 ]

NOTE: This proposal appeared as Comment 24-1 (Log #3) which was held from the A12 ROC on Proposal 24-4.Do not take the action in Proposal 24-4. Instead, revise section 5.1.3 and insert an annex note as follows:5.1.3* Where the volume and pressure available from a water supply are

determined through a waterflow test, an adjustment shall be made to the test data to account for daily and seasonal fluctuations.A.5.1.3 Flow tests that are run during the middle of a business day often do not

account for peak water demands at other times of the day or water use during other times of year. Under ideal circumstances, NFPA 24 would have a specific value to apply to all situations, but that is not practical given the wide variations of watersupplies in use and the variations of when waterflow tests are conducted. Waterflow tests conducted close to peak water usage times would need less of an adjustment than waterflow tests conducted during low water usage times. Consultation with the water authority may be necessary to determine an appropriate adjustment factor. Use of 24 hour gages at a hydrant can be helpful in determining day to day fluctuations. In addition, the user should also consider other water usage factors such as simultaneous industrial use, the potential for future demand on the system in the area of the test (depending on how well developed the area already is) and other conditions that would affect the water supply.


File Name Description Approved24_PI_56_Held_Comment_24-1_Kelly_.pdf Held Comment 24-1


While some of the material currently in section 5.1.3 is more appropriate in the annex, the basic concept of requiring some adjustment to the data is still needed in the body of the standard. It is completely irresponsible to conduct a waterflow test at a hydrant at a time of very low water demand and believe that you are going to have all of that flow and pressure available when a fire occurs a few hours later during a regular and known peak demand time.As proposed, the rule would only apply in those situations where the waterflow test is

being performed and would not apply to the development of water supply data from other sources.The concept of evaluating the water supply for possible interruptions from flood or ice

conditions has been intentionally dropped from the language because this does not have to do with the flow or pressure available. This concept should be a part of the determination as to whether the water supply is “reliable” enough to use at all, which is a completely different concept and should not be tied to evaluating data from a flow test.

In order to appropriately handle this issue, more research and test data must be reviewed. TheTC thinks that this is an issue that needs to be resolved, but does not have the time to handle this during this cycle. TheTC recommends establishing and inter-committee task group with the SSD TC to compile and review data to act on thisnext cycle. This will be reviewed with the TCC to identify any other potential TC's (i.e. NFPA 14) that may need to beinvolved in this task group.

5.2.1 Private Fire Service Mains.Pipe smaller than 6 in. (152 mm) in diameter shall not be installed as a private service main supplying hydrants. A minimum 8 in. (203.2mm)diameter pipe shall be utilized for systems supplying multiple firehydrants unless it can be demonstrated that a smaller main willprovide the proposed and future development with adequate pressure and fire-flow.


Makes this standard compatible with AWWA and other regional standards. Fire hydrants should only be connected to water mains adequately sized to carry necessary fire flows. Private fire service mains that serve residential, industrial, or commercial developments may require larger mains to assure adequate pressure and fire-flow for current and future development needs.

Committee Statement




cycle, the Technical Committee (TC) on Private Water Supply Piping Systems noted that the document was incongruent with portions of NFPA 13, NFPA 14, NFPA 20 and other design and installation standards. Furthermore, it was determined that the order that information was presented in the standard was not optimal and could be revised to make the document easier to follow. The TC developed a task group to work on a rewrite of the standard for the 2016edition of the standard. The revisions to chapter 5 addressing the definitions were made in an attempt to better correlate with the other water-based system documents. Specific revisions to the standard are as follows: -5.2.1 The concept of confirming that the main sizing is sufficient with hydraulics is important, but only where multiple hydrants have are installed. Calculating a single hydrant on a 20 foot run of pipe is not necessary and would be burdensome to contractors and AHJs. -5.4.2.1 Some agencies do not recognize alarm check valves as backflow devices. Where this arrangement is being used/approved it is imperative that these devices are listed for fire protection use. -5.9.1.2 The standard did not provide design guidance on how these supports must be designed, so the ambiguous reference to support is not helpful. Typically the FDC is supported by the wall it is running through or comes out of the ground vertically and does not require “support”. -5.9.1.3 Not all caps are listed, so requiring a listing isn’t appropriate. If the AHJ simply approves the cap, that is sufficient. -5.9.2.3 This section is intended toaddress the threading, not the entire FDC. -5.9.3.1 It is not the intent to install a check valve directly to the FDC, just in the FDC piping. -5.9.3.2 The valve arrangement requirements were rewritten for clarity and annex figures were added to provide figures that are consistent with NFPA 13. -5.9.4.3 There are many areas in the country where the temperature of the air will dip below 32 degrees Fahrenheit but will never last long enough to freeze a 4" or 6" pipe. Technically this means that freezing has been achieved because water freezes at 32° FH. This change gives allowance for these climate areas. -5.9.4.4.1 The 2013 edition was modified to require access to the ball drip. Many AHJ's require that fire department connections (FDC) are remote. NFPA suggests that the check valve for the FDC be located as close to the connection to the system as possible. This could leave long sections of underground piping with no pressure. This piping could get cut and one will not know about it until an NFPA 25 inspection is performed or the fire department pumps into the connection. Many AHJ's want water brought as close to the FDC as possible to avoid this situation. By requiring access to the ball drip, this could require a vault or deep meter box costing hundreds of dollars. This new section gives the AHJ an allowance to require the automatic drip close to the FDC and still have water on the underground piping for supervision. 5.9.5.4 Almost all the fire department connection plates indicating the connection type (autosprinkler, standpipe or both) are bought directly from the fire department connection manufacturers. Engraving these with the required inlet pressure is impractical. Also, since the sign referred to requires one inch high letters, it could be construed that the pressure information should also be the same size. In the fire sprinkler business, when a higher pressure requirement must be posted, we have custom made signsproduced and placed on or at the FDC.

5.9.1.4Fire department connections shall be equipped with listed plugs or caps that are secured and arranged for easy removal by firedepartments.




There is no need to utilize listed plugs or caps for a fire department connection. Often, the nice new brass ones that come with a listed FDC go missing and have to be replaced. To avoid repetitions of such losses, one option that building owners may choose is to replace them with vandal resistant “break away” or “knock off” caps, which are economical, unattractive to brass scavengers and they generally make poor ash trays. These devices are not usually listed and they do not need to be, because components such as FDC caps and plugs do not affect system performance.

File Name Description Approved24_Brown.pdf Cover Sheet


The use of the term "system piping" has caused confusion on just where a fire department connection (fdc) can be installed. They read this as meaning that you cannot have any shutoff valve between the fdc and the system sprinkler system. Thus the arrangement shown in Figure A.3.3.11 would not be allowed sense there is two shutoff valves shown between the fdc and the sprinklered building.The term "fire service main" is used in Figure A.5.9(b).

5.9.4.2.1The automatic drip shall be permitted to be buried where permitted by the authority having jurisdiction.5.9.4.2.2Where the automatic drip is buried as allowed by 5.9.4.2.1, the outlet shall discharge into a bed of crushed stone or pea gravel.


The 2013 edition was modified to require access to the ball drip. Many AHJ's require that fire department connections (FDC) are remote. NFPA suggests that the check valve for the FDC be located as close to the connection to the system as possible. This could leave long sections of underground piping with no pressure. This piping could get cut and one will not know about it until an NFPA 25 inspection is performed or the fire department pumps into the connection. Many AHJ's want water brought as close to the FDC as possible to avoid this situation. By requiring access to the ball drip, this could require a vault or deep meter box costing hundreds of dollars. This new section gives the AHJ an allowance to require the automatic drip close to the FDC and still have water on the underground piping for supervision.



Committee Statement













5.9.4.3 An automatic drip shall not be required in areas where the piping is notsubject to freezing.


There are many areas in the country where the temperature of the air will dip below 32 degrees Fahrenheit but will never last long enough to freeze a 4" or 6" pipe. Technically this means that freezing has been achieved because water freezes at 32° FH. This change gives allowance for these climate areas.



Committee Statement













5.9.4.3An automatic drip shall not be required in on fire department connections for systems located in areas not subject to freezing.


As presently written, this requirement may be confused as to mean that the location of the automatic drip cannot be in an area where it would freeze. In actuality, the automatic drip is not required on any part of a system that is located in a geographical area that is not subject to freezing climates.

5.9.5.2Fire department connections shall not be connected on the suction side of fire pumps.


This is important information that should be located in this section. Renumber accordingly.



Committee Statement













5.9.5.1 *Fire Remote fire department connections shall be located at the nearest point of fire department apparatus accessibility or at a location approved by the authority having jurisdiction.


the section needs to be specific in that it is referencing remote fire department connections. Fire department connections mounted on buildings are under the jurisdiction of NFPA 13. Identifying "remote" keeps the informatoin specific to remotely located hydrants.



Committee Statement













5.9.5.2 *Fire Remote fire department connections shall be located and arranged so that hose lines can be attached to the inlets withoutinterference.





Committee Statement













5.9.5.3 *Each fire remote fire department connection shall be designated by a sign as follows:

(1) The sign shall have raised or engraved letters at least 1 in. (25.4 mm) in height on a plate or fitting.

(2)





Committee Statement

* The sign shall indicate the type of system for which the connection is intended.













5.9.5.4 Where the system demand pressure exceeds 150 psi (10.3 bar), the sign required by 5.9.5.3 a sign located at the fire department connection shall indicate the required design inlet pressure.


Almost all the fire department connection plates indicating the connection type (autosprinkler, standpipe or both) are bought directly from the fire department connection manufacturers. Engraving these with the required inlet pressure is impractical. Also, since the sign referred to requires one inch high letters, it could be construed that the pressure information should also be the same size. In the fire sprinkler business, when a higher pressure requirement must be posted, we have custom made signs produced and placed on or at the FDC.



Committee Statement













5.9.5.5Where a fire remote fire department connection only supplies a portion(s) of the building, a sign shall be attached to indicate the portion(s) of the building supplied.





Committee Statement













6.1.1All Except as permitted by 6.2.1, all valves controlling connections to water supplies and to supply pipes to sprinklerswater-based fire protection systems shall be listed indicatingvalves.




During the previous revision cycle the words “listed indicating” were deleted from 6.2.1. This created a conflict whereby 6.1.1 and 6.2.5 call for listed indicating valves on water supplies, but 6.2.1 does not. The proposed text is offered as a resolution to this conflict. Additionally the modification to 6.2.1 would require the configuration to be acceptable to the AHJ and the proposed Annex text would offer an explanation for the matter.Also, in 6.1.1 the specific reference to “sprinklers” was revised to “water-based fire protection systems”, since private fire service mains supply other types of systems as well.



Committee Statement




cycle, the Technical Committee (TC) on Private Water Supply Piping Systems noted that the document was incongruent with portions of NFPA 13, NFPA 14, NFPA 20 and other design and installation standards. Furthermore, it was determined that the order that information was presented in the standard was not optimal and could be revised to make the document easier to follow. The TC developed a task group to work on a rewrite of the standard for the 2016edition of the standard. Specific revisions to chapter 6 to the standard are as follows: -The title of Chapter 6 was changed from “Valves” to “Water Supply Connections” to better describe the material covered within the chapter. -Revisions in section 6.1 were to better call out the permitted exceptions to indicating valves and to permit non-listed tapping sleeve and valves assemblies in connections to municipal water supplies. -Section 6.2 was revised to provide clarification to where control valves are required to be installed in relation to check valves and fire department connections. Also clarification was made that shut-off valves refer to control valves and references to shut-off valves changes to control valves in the chapter. -Wording changes were made in sections 6.5 and 6.6 to provide increased clarity of requirements.

(1) Both control valves shall be outside screw and yoke or listed indicating valves.

(2) All fittings inside the building, except the drain tee and heater connections, shall be under the control of a listed valve.

Exception: Welded fittings do not require a control valve.


welded fittings should not require a control valve as they by their very nature, are typically not removed



Committee Statement

Resolution: All connections to water supplies should have a control valve. This concept may be better fitted for the NFPA 22 TC.

Hydrants shall be of an approved type and have not less than a 6 in. (152 mm) diameter connection with the mains. be listed for fire protection.


This standard requires valves to be listed. Hydrants are a vital component of private fire service mains and they should be listed as well. Listed hydrants are readily available and are not cost prohibitive. The minimum pipe size requirement has been deleted as it is located in 5.2.1 which is more appropriate. The only instance where a hydrant should not have to be listed is a draft hydrant which is outside the scope of this standard.

7.3.6The means of hydrant protection shall be arranged in a manner that does not interfere with the connection to, or operation of, hydrants.


2006 Fire code section 508.5.6 states that hydrants subject to impact by motor vehicles, shall be provided with guard posts or other approved means that comply with section 312.

Section 312 states that the spacing between posts shall not exceed 4 (four) foot on center and not less than 3 (three) feet from protected object. The demensions stated have been investgated numerous times in the field to confirm that it is not possible to provide the protection required using 4 (four) posts.

Currently architects/designers are calling for the use of 4 posts, it is not possible to maintain the 4 foot on center between posts and the 3 foot clearance from the protected object without adding an additional post.

This concern is usually handled through the architect of record for the project, but it comes with a change order/additional cost to the owner.

This proposed revision editorial in nature, to clarify the intent. It is common practice for some industrial fire brigades to store their hose at their fire halls and/or on their fire trucks, but as written the current text seems to imply that it is mandatory to put the hose in hose houses or on reels or carriers in weatherproof enclosures.



Committee Statement




cycle, the Technical Committee (TC) on Private Water Supply Piping Systems noted that the document was incongruent with portions of NFPA 13, NFPA 14, NFPA 20 and other design and installation standards. Furthermore, it was determined that the order that information was presented in the standard was not optimal and could be revised to make the document easier to follow. The TC developed a task group to work on a rewrite of the standard for the 2016edition of the standard. Specific revisions to chapter 8 to the standard are as follows: -8.1.2 This section was split into two requirements. The language was modified to replace the term weatherproof with weather protected to allow for more freedom in the design. -8.3.1 This section was deleted because the term substantial construction was vague and created a wide range of interpretations. -8.3.1 The reference to bringing in hose houses for use was struck because it was redundant with 8.2.3.







8.3.1Hose houses shall be of substantial construction on foundations stable foundations .


adding "stable" ensures that the hose houses are not installed on loose soils



Committee Statement

Resolution: The presence of a foundation is not needed in all cases. The focus should be on the fact that the hose house is weather and vermin protected, not the actual construction methods/components used.

Committee Statement




cycle, the Technical Committee (TC) on Private Water Supply Piping Systems noted that the document was incongruent with portions of NFPA 13, NFPA 14, NFPA 20 and other design and installation standards. Furthermore, it was determined that the order that information was presented in the standard was not optimal and could be revised to make the document easier to follow. The TC developed a task group to work on a rewrite of the standard for the 2016edition of the standard. The revisions to chapter 10 addressing the definitions were made in an attempt to better correlate with the other water-based system documents. Specific revisions to the standard are as follows: • 10.1 Piping charging statement was added. Then (3) subsections were added. There is the ability to use the table, the ability to use pipe specifically listed for underground use, and the allowance to use steel pipe between the FDC and the check valve. The steel piping references were removed from the table since steel pipe is required to be listed other than in the FDC line. A new table was added referencing the ASTM standards of steel pipe used in this part of the system. Fitting references and discontinued AWWA standards were removed from the table. Brass pipe was added to the table. A statement was added that when a listed product is used, the installation instructions supersede the standard. Moved type and class requirements to the annex. Added allowance to extend underground piping into the building as allowed by NFPA 13. • 10.2 The fitting section was reorganized to mirror the pipe section. A charging statement was added and the three subsections permit either use of the table, use of a listed fitting or use of an approved fitting. Cast Bronze Fittings were added to the fittings table. The fitting standards in the pipe standards were moved to the proper table. A statement was added to allow underground fittings to be used aboveground to transition to above ground piping. • 10.3 Organized a chapter on connection pipe, fittings an appurtenances. • 10.4 Protection. Created a title of protection and then broke it up into corrosion, freezing and protection from damage. Added allowance to use heat tracing on underground when specifically listed for such use. Addedlanguage to require contact with the rail authority when running under tracks. • 10.5 Pipe running under buildings. Made it very clear that all three conditions for running under the building were needed when exceeding 10’-0” into the building. Also added requirements to mechanically restrain all joints when exceeding 10’-0”. Added annex language that this applies to new and existing installations. • 10.6 Restraint. Created a charging statement to indicate that one of the three methods is to be used. These are thrust blocks, mechanical restraint and other methods. • General. Various word revisions, grammar and sentence structure has been done throughout the chapter.

13.2 Mains Not Supplying Hydrants.For mains that do not supply hydrants, sizes smaller than 6 in. (152 mm) shall be permitted to be used, subject to the following restrictions:

(1) The main shall supply only the following types of systems:

(a) Automatic sprinkler systems

(b) Open sprinkler systems

(c) Water spray fixed systems

(d) Foam systems

(e) Class II standpipe Standpipe systems

(2) Hydraulic calculations shall show that the main is able to supply the total demand at the appropriate pressure.

(3) Systems that are not hydraulically calculated shall have a main at least as large as the riser.




This change is proposed to align 13.2 (e) with the text of 5.2.2 (e), which was revised during the last cycle to delete the “Class II” reference. As discussed then, there should not be a requirement which specifies a 6” minimum water supply for all Class I & III standpipes. NFPA 14 requires that all new standpipes be hydraulically calculated, so this standard should not dictate a minimum size for the private fire service mains that supply them.

Committee Statement









A.5.4 Where connections are made from public waterworks systems, such systems should be guarded against possible contamination as follows (see AWWA M14 or local plumbing code or consult the local water purveyor ):

(1) For private fire service mains with direct connections from public waterworks mains only or with fire pumps installed in the connections from the street mains, no tanks or reservoirs, no physical connection from other water supplies, no antifreeze or other additives of any kind, and with all drains discharging to atmosphere, dry well, or other safe outlets, an approved double check valve assembly is recommended.

(2) For private fire service mains with direct connections from the public water supply main plus one or more elevated storage tanks or fire pumps taking suction from aboveground covered reservoirs or tanks (all storage facilities are filled or connected to public water only, and the water in the tanks is to be maintained in a potable condition), anapproved double check valve assembly is recommended.

(3) For private fire service mains directly supplied from public mains with an auxiliary water supply, such as a pond or river on or available to the premises and dedicated to fire department use; or for systems suppliedfrom public mains and interconnected with auxiliary supplies, such as pumps taking suction from reservoirs exposed to contamination or rivers and ponds; driven wells, mills, or other industrial water systems; or for systems or portions of systems where antifreeze or other solutions are used, an approved reduced-pressure zone-type backflow preventer is recommended.

(4) For private fire service mains with fire department connections located within 1750 ft (533.4 m) of a non potable water source, an approved reduced-pressure zone-type backflow preventer is recommended.


This is an AWWA requirement that is being increasingly enforced. Since this standard includes annex language on backflow prevention, this should be added.

As there is normally no circulation of water in private fire mains, they require greaterdepth of covering than do public mains. Greater depth is required in a loose gravelly soil (or in rock) than in compact soil containing large quantities of clay. The recommended depth of cover above the top of underground yard mains is shown in Figure A.10.4.1.

Committee Statement










A.10.8.3A method for providing thrust restraint is the use of restrained joints. A restrained joint is a special type of joint that is designed to provide longitudinal restraint. Restrained joint systems function in a manner similar to that of thrust blocks, insofar as the reaction of the entire restrained unit of piping with the soil balances the thrust forces.

The objective in designing a restrained joint thrust restraint system is to determine the length of pipe that must be restrained on each side of the focus of the thrust force. This will be a function of the pipe size, the internal pressure, the depth of cover, and the characteristics of the solid surrounding the pipe.

The following documents apply to the design, calculation, and determination of restrained joint systems:
