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??

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...
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...
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...
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...
Per NFPA 13 section 8.6.2.1.2.1 it states that the protection area of each sprinkler in the small room shall be the area of the room divided by the number of sprinklers.
For example I have a 12'x11' patient room with 1 head in it, so in my calcs I calculated minimal coverage of 150sf. BUT, due...
Just digging into protection of stairs, when NFPA 13 2013 edition calls out protection under the first "accessible" landing, is this underneath the 2nd floor landing as you look up?
Thank you,

I have taken the advanced hydraulics for Level 3 water based and found this to be very hard. I have failed it once and decided this time to the online training on FireTech. The level 1 & 2 Firetech books were very helpful but level 3 is going to require much more.
Does anyone know the fail/pass...
We are going to design and install a fire pump house on a large poultry plant. The underground supply loops around the plant and ties into the city water with a backflow preventer.
I would like if possible to tie into that system and basically boost the whole facility which is supplied by...
Got a quick question, I have read this somewhere but cant find it again, arggg. We have a situation where a single 1 1/2" hose valve is against a fire rated wall. The owner wants another hose valve and the other side of the wall, and I believe you can connect to the existing piping and supply...
I have an old 3 story hotel that has a walkway that loops the entire building for 3 floors and is exposed to the elements. Think of an old hotel where the stairs are exposed and so is the wrap around covered walkway.
Our thought we be to install a new dry system that is installed and loops this...
Has anyone used Hydracalc to perform a calc to balance the ceiling demand with the rack demand?
I am a little lost as to exactly how to make this work.
Thanks!
I have a Noncombustible attic with a Mechanical Platform in a large Dentist Office. The mechanical platform is above the drop clg constructed of steel beams with a concrete deck and a steel peaked roof above it.
Now the FAU's are gas fired so we are going to protect above that platform with...
Hey guys we are pricing a existing building that is entirely made up of trampoline flooring, essentially it is a gym type of facility, but I am trying nail down the exact occupancy hazard.
My first guess is light hazard, any thoughts on that?
Thanks,
Ok for a short understanding of this job, it is an existing building, 23' to top of storage, 30' to peak. Now ESFR sprinkler will not work do to the massive amount of ductwork above and the fact that you are limited to moving around ESFR sprinkler to avoid obstructions. So I am left with CMSA or...
Question, do you still have to maintain spacing rules against walls when the walls are framed to the deck but the sheetrock stops at 2'-0" from deck.
So there is no obstructions to the sprinkler spray pattern, but walls will scattered about in a large space.
Thanks,
Got a quick question on Fire pump Selection(been a long time since I did this myself), I am sizing a pump for a non high rise NFPA 13 Building, light hazard attic with Attic Sprinklers.
#1 The City water is insufficient to supply the Attic Hip Sprinklers and 48' of elevation & a DCDA Backflow...
