I'm working with a city inspector who is adamant that we add a second non-rising stem valve (NRS) in the fire sprinkler service main just before the building. The first valve being in the street at the live-tap location with the roadway box.
Is a valve required on the service main before the building?
The requested location would place the valve under the sidewalk, accessible by T-handle wrench only, prohibiting reliable supervision of any kind.
I can't seem to find any language in NFPA 24 that I can use to argue against the second unsupervised valve. I don't see any value in the position the inspector has taken and requested a copy of the city ordinance requiring the additional valve.
Installing the second valve wouldn't be a huge deal but certainly seems like an unnecessary opportunity for an unsupervised valve to get closed or fail. I would like to hear what others in this community think and if anyone has something to offer.
Thanks in advance.
