So, in that case, would they be required to eliminate the non-indicating gate valve? Or just add the PIV? I mean, if the gate valve is closed, it really doesn’t matter what position the PIV is in.
I know there are some jurisdictions in Nevada where we’ve been required to provide wall PIVs for the system control valves. But I’m not 100% certain what their intent was in requiring it. Is it about knowing if the valve is open or closed, or is it about being able to control it from the building exterior? -Kyle M From: Sprinklerforum [mailto:[email protected]] On Behalf Of Prahl, Craig/GVL Sent: Monday, December 3, 2018 2:27 PM To: [email protected] Subject: RE: [EXTERNAL] Re: RE: PIV NFPA 24 calls for indicating type valves on water supplies serving sprinklers. Non-indicating type valves for sprinkler water control are permitted only when approved by the AHJ. So it’s totally within the right of the AHJ to require a PIV outside the room on the UG run-in. In some cases when there is no place to install a PIV, sometimes the AHJ has allowed a Wall Post Indicator Valve to be used.

An exterior door opens to interior of riser room which contains a backflow preventer with two indicating control valves, a rise check valve, and a water flow switch. Underground line to building has a nonindicating gate valve in roadway box some distance from door to riser room. AJH says a post indicator valve must be installed outside riser room. We believe the current arrangement of piping and valves meets the standard without the PIV Please comment. _______________________________________________ Sprinklerforum mailing list [email protected]<mailto:[email protected]> http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org<https://urldefense.proofpoint.com/v2/url?u=http-3A__lists.firesprinkler.org_listinfo.cgi_sprinklerforum-2Dfiresprinkler.org&d=DwMFaQ&c=OgZOSER8c1RLeytEexU279Q2qk0jVwkrOdYe5iSi-kk&r=_w721WvezJkWUVteY4FMhecHAoDqOn85ooHi6vIkMag&m=lXsJUcku6Cs3Ph_G1QTW4M6ffWMQo2QFYsrknTByiwQ&s=_JVHbOtWOq8UdJrV7L3LmA-ftMxo9n8OgtXbU7rfkek&e=> ________________________________ NOTICE - This communication may contain confidential and privileged information that is for the sole use of the intended recipient.
