Public Comment No. 4-NFPA 24-2017 [ Sections 5.9.2.1, 5.9.2.2, 5.9.2.3, 5.9.2.4 ]

5.9.2.1

The When not designated by the AHJ, the fire department connection(s) shall use an NH internalthreaded an internal swivel fitting(s) with an with NH standard thread (s.) , except as permitted by5.9.2.3 and 5.9.2.4 .

5.9.2.2

5.9.2.3

Where local fire department connections use threads that do not conform to NFPA 1963, the AHJ shalldesignate the thread to be used.

5.9. 2.4

Nonthreaded couplings shall be permitted where required by the AHJ.

5.9.2.4.1

Nonthreaded When nonthreaded couplings are designated for use by the AHJ, the couplings shall belisted.


What is the purpose for so much extra verbiage? It seems as though this section could be significantly shortened since so much of it is repetitive and redundant.

One of our consultant was counting the pipe segments of the network for deciding the number and location of isolation valves, while I understand that only outlets should be counted.

7.1.1.2

A listed control valve shall be installed in each hydrant connection.

7.1.1.2.1

A valve required by 7.1.1.2 shall be permitted to be a listed, nonindicating valve, such as an undergroundgate valve in a roadway box.

7.1.1.2.2

Valves required by 7.1.1.2 shall be installed within 20 ft (6.1 m) of the hydrant.

7.1.1.2. 1 2 .1

Valves shall be clearly identified and kept free of obstructions.

7.1.1.2. 2 3

Where valves cannot be located in accordance with 7.1.1.2.1, valve locations shall be permitted whereapproved by the AHJ.


As currently written in 7.1.1.2, the standard does require a fire hydrant’s control valve to be listed. This omission should be rectified.

Additionally, while a Committee Statement was not provided to explain why Public Input No. 31 was resolved, it was expressed during the first Draft Meeting that indicating valves in accordance with 6.1.1 should not be necessary to control a fire hydrant and that it should not be necessary to obtain AHJ permission to utilize a nonindicating valve in a roadway box. If this is the Committee’s intent then it should be clearly stated in the standard.

Public Comment No. 3-NFPA 24-2017 [ Section No. 7.2 ]

7.2 Number and Location.

7.2.1*

Hydrants shall be provided and spaced in accordance with the requirements of the AHJ.

7.2.2

Public hydrants shall be permitted to be recognized as meeting all or part of the requirements ofSection 7.2.

7.2.3*

Hydrants shall be located not less than 40 ft (12 m) from the buildings to be protected.

7.2.4

Where hydrants cannot be located in accordance with 7.2.3, hydrants located closer than 40 ft (12 m) fromthe building or wall hydrants shall be permitted to be used where approved by the AHJ.

7.2.5

When hydrants are located between a fire pump and its water source, the hydrant shall be identified in amanner approved by the AHJ.


Many times, a fire hydrant is placed between a fire pump and where the private main connects to the public water system. In the event the fire pump fails to operate, this hydrant provides a water source for the fire department to use when supplying the FDC. The problem we find is that these hydrants are not identified in any way, so they look just like all of the other hydrants. Should the fire pump be operating properly and this hydrant is used as a water source, it will steal water from the fire pump. This will then provide less water to the sprinkler system and to the other private fire hydrants that the fire pump supports. These hydrants should be identified in a way that tells firefighters not to use them when the fire pump is in operation. Since so many departments have different requirements for how their hydrants are marked, it should be the responsibility of the AHJ to develop a system of identifying these hydrants and their use.

These revisions are offered for the following reasons:

- 10.4.3.2.1: Since 10.4.3.2.2 allows pipe as per 10.1.1 (ie. PVC or PE), the trench must be covered to protect it from damage.

- 10.4.3.2.1.5: The 24 in. requirement is in conflict with 10.4.3.1.2, which only requires 12” clearance for pipe passing below a footing or foundation.

- 10.4.3.2.1.5.1: Deleted since it is redundant to 10.4.3.1.2.1, which incidentally, does not require AHJ permission to utilize a sleeve.

- 10.4.3.2.2.1: Since 10.4.3.2.1.3 already requires a trench to be noncombustible, the allowance for aboveground piping should be automatically permitted. Above ground piping should be allowed if the trench is built using brick or block or stone. Concrete should not be mandatory.

- 10.4.3.2.4: Deleted since it is in conflict with 10.4.3.2.3. As currently proposed 10.4.3.2.4 would require 2 valves within close proximity of each other – one immediately outside the building and then one right inside the building, in the trench.

When piping is installed in a trench under the building, the bury depths of 10.4.2.2 shall not apply once thepipe is more than 10 ft (3.0 m) into the building.


The bury depth rules for freezing and protection of the piping from damage should not be applied once the pipe is far enough into the building. The 10 foot limitation is arbitrary but was chosen for freeze protection purposes.

As currently proposed, the text on flushing still speaks to “collection of foreign material”, but the standard does not call for such collection, it only requires that the water is verified to be clear.

Public Comment No. 12-NFPA 24-2017 [ Section No. 10.10.2.1.3.1 ]

10.10.2.1.3.1

Where the flow rates established in Table 10.10.2.1.3 are not attainable, the maximum flow rate available tothe system shall be acceptable.

10.10.2.1.3.2

In lieu of flushing with the waterflow rates prescribed in 10.10.2.1.3 and 10.10.2.1.3.1 water main swabbingof the piping, by the forceful introduction of a large spnge through the pipe, to remove debris, shall bepermitted.

10.10.2.1.3.2.1

Water main swabbing shall be repeated, as necessay, until the last sponge that has fully penetrated thepipe is clean and the discharge water is clear.


Water conservation has become a very large issue in many regions and the water flow rates prescribed by the standard are very high and often not permitted by the municipal authority. Water main swabbing is an excellent alternative to the current flushing requirements. It is more obtrusive than flushing and thus more effective and can use significantly less water to achieve the desired results

Public Comment No. 16-NFPA 24-2017 [ Sections A.1.4, A.3.2.1 ]

Sections A.1.4, A.3.2.1

A.1.4

It is the intent of the committee to recognize that future editions of this standard are a further refinement ofthis edition and earlier editions. The changes in future editions will reflect the continuing input of the fireprotection community in its attempt to meet the purpose stated in this standard. Compliance with allrequirements of a future edition could be considered as providing an equivalent level of system integrity andperformance of the system.

A.3.2.1 Approved.

The National Fire Protection Association does not approve, inspect, or certify any installations, procedures,equipment, or materials; nor does it approve or evaluate testing laboratories. In determining theacceptability of installations, procedures, equipment, or materials, the authority having jurisdiction may baseacceptance on compliance with NFPA or other appropriate standards. In the absence of such standards,said authority may require evidence of proper installation, procedure, or use. The authority havingjurisdiction may also refer to the listings or labeling practices of an organization that is concerned withproduct evaluations and is thus in a position to determine compliance with appropriate standards for thecurrent production of listed items.

This new langauge (A.1.4) needs to be correleated with all NFPA documents - NFPA 13R does not includethis annex section


This annex language was accepted to NFPA 13, NFPA 13D, NFPA 24 and NFPA 14. This is a positive change to the standard and this new language should be correlated with the other NFPA documents.
