[Sprinklerforum] Re: Gang drain crossing seismic joint

I agree with all in this case. Low point drains and inspection’s test can cause water damage in earthquakes. In Anthony C.’s home turf the most common break I saw in what our E-376 calls tilt-up town were in these lines. 1” tee’d over to wall, a 90 down, and almost immediately a 4” piece of

[Sprinklerforum] Re: Gang drain crossing seismic joint

Steve, three points here. §18.4.1 requires clearance for a drain extending through a wall, floor, platform, foundations.   §18.5.1.6 omits any bracing requirements for drain piping downstream of the drain

[Sprinklerforum] Re: Gang drain crossing seismic joint

If the life safety system will operate with or without the drain and if it being damaged won't cause damage to the primary life safety system and there is no text stating such ancillary piping is required to be braced, I'd say stick a fork in it, you're done. Sign, seal and deliver. Craig

No, and that's exactly my reasoning too. I should have said in my post that I'm not 100% certain because it's being submitted to a preposterously fickly AHJ and they're historically very subjective, but my personal opinion is that it's not required for the reason that you mention. Steve

[Sprinklerforum] Re: Gang drain crossing seismic joint

If the section that crossed the expansion joint were to be torn apart would it have any functional effect on the bldg. sprinkler or standpipe systems? Craig Prahl | Jacobs | Fire Protection SME - Special Hazards | craig.pr...@jacobs.com |

[Sprinklerforum] Re: Gang drain crossing seismic joint

I would say that drain piping downstream of the valve is not required to be braced. One of the things I like to impress upon people when teaching seismic is that you brace and secure the pipe to keep the water in the piping. It is also to insure that piping required for the operation of the

[Sprinklerforum] Gang drain crossing seismic joint

All (especially Californicators): We have to cross a seismic joint with the piping that supplies a combination standpipe in a mid-rise building (no PRV's to test). As a combo, there's a collection pipe for sectional test and drain discharge, and for reasons peculiar to this building, our

I would hope there would be a provision that if you hydraulicly prove it whit one connection that should be acceptable. Christopher S. Wilson SET Project Design Manager Treasure Valley Fire Protection 2731 S. Saturn Way Boise, ID 83709 Phone: 208-362-1888 Fax: 208-362-2207 please note all TVFP

[Sprinklerforum] Re: FDC for Standpipe

That’s hydraulics. If you can deliver the demand with no more inlet pressure than the FD is willing to accept, I think you can use 4” for the FDC. 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

To all - review NFPA 14 -2024 as it has new requirements for 4" and 5" storz connections. 4" is limited to 500 GPM per connection 5" is limited to 750 GPM per connection Unfortunately, I'm at a conference where my internet connection is very limited, otherwise I would give you a section

Brian, Yes, I have been required to provide such a connection in the past.  It has been rare, and it was a gorilla sized high rise building. For me arguing with the AHJ over this seemed pointless. sincerely, Ken Wagoner, SET

[Sprinklerforum] FDC for Standpipe

Anybody ever had an AHJ required a 4-way FDC with (4) Storz connections to feed a standpipe? I get the (1) 2-1/2" connection per 250 gpm but you're also allowed a "large diameter" hose connection. In this case the current FDC is a 5" Storz on 6" underground. Thank you, Brian Harris, CET BVS
