Sl3656, I did exactly what Travis said when I ran into that issues with a materials supply building. The only option I could come up with was splitting the system in 2 systems with a single tank mounted air compressor & 2 air maint. devices.

Is there any code in NFPA 13 about reusing threaded fittings for a system that we had to turn around and modify per changes to the contract drawings??

Love the product, little heavy if you get the entire assembly with control valve and check valve, but well worth it as a one time installation. Better than searching for all the parts. And I found they are about $100 cheaper than all the parts assembled together from Victaulic.
Eric Hendrix...
I have a quick question, is there different standpipe requirements for buildings per IFC for commercial buildings versus dorms or hotels? If any type of building is over 30' to the highest story you are required to have a class III standpipe per the requirements of IFC in which you then...
Good stuff, I know in the boondocks of MS I have steered us away from galvanized piping especially after the language changed in NFPA 13 2016 edition either though the state is still using 2013 edition.
I am still very iffy about using Sch. 7 but I do think I am going try and steer us toward...
Skdesigner,
Yes I have heard of this also, I could see where you might want an additional hanger here and there to help support the pipe from sagging

I am thinking of making a change to use more sch. 7 pipe, we do mannnnny jobs that have no or limited specs, many design builds and VE nearly everything.
I want to make the move to use more Dyna Flo type pipe or other thin-wall pipe. I have found that a stick of 4" x 21' dyna flow pipe is $6.00...
Sprinklerlifer is correct and that method works great. I designed a church that was built as A frame building, half was exposed half wasn't. At the peak there was ceilings below that called for a 12' drop. I sent the drop down 10' then used a flex drop from that point.
The ceiling brackets do a...
I have 2016 edition. I have read that putting a pressure gauge on the cold water supply would at least give you an operating pressure.
I cant see how obtaining a flow would be needed, but I have nothing to back that up.

Calculating 2 sprinklers. I am just trying to figure how to flow it. There might be hydrants way down the road.

I have been reading and digging to find out the best method to perform a flow test for a sprinkler system we are installing in a beach home.
I would like to connect to the 1" cold water copper line at the water heater, but I need to know if that is sufficient to supply 2 sprinklers.
I have...
I have a local AHJ asking me for a code that will help him exclude the requirements that the city water wants a water meter on a dedicated fireline. I find that to be fairly crazy but I have seen it here in a couple places in MS. ( this is a small town in MS)
I have read NFPA 24 and see that...
Travis,
I agree I am starting to see the use of Intermediate heads in commercial office space. I kept wondering why I kept seeing this, at first I thought someone was using spare heads off a shelf.
Last year I saw a nursing home that another company did and all the sprinklers were 200°. I...
Correct I didn't find anything specifically to this as well but wanted to be sure. This is not an FM job.
Thanks buddy,

I have nearly completed a project and the Fire Marshall has asked does the wall openings need protection for conveyors connecting the new and old parts of the plant together. I am trying to locate if NFPA has anything particular about this other than room design requirement for openings but this...
