And don't set the fire department up for failure.

Rick’s and Steve’s comments are spot on. Give the fire department what they
need/want. Do not install something that no one will ever use in an emergency
condition.

Steve’s guidance is the best. When it comes to hose valves and standpipe
requirements, always verify with the AHJ to find out what they want. Rick

To Rick’s comments:
Concur, and also offer that while the standard doesn’t require a valve where
there is no roof access, I am aware of numerous AHJ’s who do. The stated
intent of the rooftop connection(s) is to enable forward flow testing of the
system. However – and this goes to my mantra of many years now – it is
incumbent on the designer to verify with the serving FD is they require roof
connections that they may use for firefighting. I have been made aware of
several fire incidents that used roof connection hose streams and I am also
aware of fireground strategies that encompass these connections.
The foregoing is my opinion only and does not represent NFPA or the NFPA 14
Technical Committee, nor intended to serve as an interpretation of the standard.

Subject: [Sprinklerforum] Re: NFPA 14 2019 Hose Connection on the Roof
This is my opinion only from what I remember after being retired for ten years.
The requirement for installing a hose valve is driven by the stairway
requirements found in the building code which requires at least one stairway
providing access to the roof.
If the stairway extends to the roof, then a hose valve is required at the top
landing or on the roof.
If there is no roof access from the stairway, then no hose valve is required.
The fire service will use the hose valve where they have safe access from the
stairway but they will not walk across the roof dragging fire hose to hook up
to a hose valve located where no safe access was provided.

There are people here with more experience than I, but if one outlet goes to
the roof, the requirement is met.

If I have 3 stair towers and the middle on has access to the roof and I provide
a connection as required by 7.3.2.7* “Hose connections shall be provided at the
highest landing of stairways with stairway access to a roof”, do the other (2)
not have to go to the roof because of 7.3.2.9.2 “The hose connection required
by 7.3.2.9 shall not be required where at least one hose connection in
accordance with 7.3.2.7 is provided in the building”.
