Fire sprinkler education on the NFPA Standards. My goal is to create a page where apprentices, fitters, anyone involved in fire sprinkler install, project management or design can come to better understand NFPA 13 , 13R, 13D, 14, 20 and 25. I started my career as a sprinkler fitter in 2005 and found my real passion for the business when I started teaching the trade for local 550 Bostons training center in 2018. Subscribe so I know you want me to keep making videos ! Thanks !
NFPA 13 3 & 4 Times Rule fire sprinklers spraying over horizontal and around vertical obstructions
NFPA 13 3 times rule and 4 times rule is used for Obstructions to Sprinkler Discharge Pattern Development. This will position the sprinkler head to spray over horizontal obstructions within 18 inches of deflector and around vertical obstructions. This is a full lesson to understand the 3 and 4 times rules.

Sign up and you will get on the list ! 💪 look up local 550 Bostons sprinkler fitters union and give them a call to get details
Great !!!
Great lecture !!!

Been installing sprinkler systems around 20 yrs now that is some beautiful looking work there good job
Thanks 👍

Why big duct at 8:15 ruclips.net/video/V0yOc47MkOY/видео.htmlsi=BNHpzP79gbJl2fr-&t=495 is NOTobstruction and small pipe @7:28 is obstruction and need to follow 3x rule ?
@ADOWAI 7:28 I was going over an example of how to use the 3 times rule. And then went to explain how when using specifically the standard spray upright and pendant in light and ordinary hazard occupancy only structural elements have to be acknowledged when spraying over an obstruction. Unless the obstruction is over 4’ wide. Let me know if you are understanding now. Thanks
THANK YOU FOR THIS VIDEO!!!!
Your welcome!! 😎👍
Wasnt a question but thanks for the info if your telling the truth
Your welcome. And yes I always tell the truth when doing RUclips. I don’t put it on RUclips unless I can reference to NFPA 👍
Super, i did not not understand what you spoke if obstruction over 4 feet? you need to make more videos about obstruction/installation as there are too many videos on this subject
Thank you. Yes my next video is on obstructions over 4 feet. I have a couple more videos I plan on making about obstructions.
Joe thanks your excellent video, so i will go residential high rise building quick response? where i can find position of QR sprinkler below ceiling in NFPA standard section?
If it’s a residential building I would assume the units would have residential style sprinkler heads. Check out my video on obstructed and unobstructed construction I go over distance below ceiling for all style heads 👍
nice one bro!! lot of like this definitions need to be clarified, thanks a lot and keep going
Thanks, will do! 😎👍
Perfect explanation. All clear !
😎👍
Joe, why you made limited videos? Why not continue other videos which have unique topic? Like Deluge valve etc
I do plan on making more videos. I want to cover all the different style sprinkler system valves and fire pumps.
Appriciated, excellent videos. No videos available on website regarding the obstruction
Thank you !
Awesome content. Thanks Joe.
Thank you 😎👍
Ohh man, thanks..❤❤
Your welcome ! 😎👍
Buddy…. You're the man. You have been so helpful.
Thank you!! I appreciate that and happy to hear 😎👍
Nice work Joe Joe you got the Automatic Hand book ? Its better than the standard npfa13.
Thanks ! Yes I have a membership with NFPA codes online!
Thanks Joe it’s refreshing how clearly you explain things. I think you would put these kinds of videos more often
Your welcome and thank you for the comment. I’m working on a video now on the 3 and 4 times rule. I’m trying to get a video out every 2 weeks,this one I’m working on has taken alittle longer. Should be done soon !
Thanks bro!
No problem!
What's the rule when say there's only two steel beams affecting a line in obstructed construction? When can the sprinklers return to 1-12 below deck?
You should go back to 1-12” below the deck as soon as the beams that are above the heads are spaced over 7’-6” on center. You could keep them at 1”-12” down even if it is obstructed construction as long as the spray pattern isn’t obstructed by the beams. You can figure that out using the beam rule. Going 1-6 inches below the structural members, max 22” is just an option. Let me know if this helps !
I only have two beams about 20" in depth and 5' apart that run horizontally across the center of the branch line. One head falls directly under the pocket of the beams and the rest of the heads on the line are spaced 8' spart. My question is what distance can I go back to 1-12 on the other side of the beams? The next head after the beam is 3'9 from the side if it. Can I run that head and the rest down the line at 1-12"?
@@austinhologroski yes! Sounds like you can run that head and the rest down the line at 1”-12”.
@@NFPAJoe thanks 👍
FPE here, you got yourself a new subscriber! Loving your videos.
Awesome, thank you!
Well done bro.
Thank you !
Smart way you put it Joe , I like this .
Thank you 😎🤙
Excellent explanation. thumbs up
A Joe wondering can you do video on above and below sprinkler heads when add when not?
Hey! Yea that’s a good topic 👍.
@jetsgang It applies in wood structure ceiling ( or combustible insulation ) you got to protect both. Or when there is 2 sets of wood joists.
Above and below coverage can have a lot of different situations. Definitely can be because of combustible construction above the ceiling like mentioned or could be for cloud ceilings, or slatted ceilings. Are you in any of these or putting heads above and below obstructions like duct work ?
@@NFPAJoe the duct takes up almost whole room it’s was a electrical room duct was tight to concrete deck so head is obstructed…it no Ceiling in room all uprights it didn’t make sense me cuz we only added 1 head above on one side of room meaning that head was blocked from deck it’s not going spray the other side of the room
@@NFPAJoe I wish I could just show u pic so you would understand more see it then we use 155 I thought electrical rooms normally 200
Nice work Joe. It pretty much applies for ESFR , CMDA, CMSA application. I am actually showing that in every drawing I send in the field, for guys to keep an eye while they installing
Thanks ! Awesome idea to have it on the install prints for reference. 😎👍
@@NFPAJoe Yeap,.. been a fitter in the past I know if we make it easy for the field guys and informative , less mistakes and better results are made.
Guys hurry the fuck up the foreman is here :)
Hahaaa 😎👍
👍
Joe you a foremen , project manager.? . I worked in the field for about 11 years then another 8 design took a break for 3 years now I m back 6 months Are you on Instagram how can I contact you ?
Heyyy. I am currently a foreman. I’ve been in the field since 2005 and I have been a trainer at local 550 training center for 5 years as a second job. You can email me at sprinklahfittah@yahoo.com
@@NFPAJoe I can tell from the tone of your voice . I started in the field 97 but I been taking time off few years here and there , however I was lucky to work with a good foreman like yourself in service. He had my hands on in every dry pipe that exist out there. Internal resets were fun back in the days.
A Joe was wondering can you do video on above and below sprinkler heads my foreman has me adding bunch heads just for nothing
I have seen this before but seem to apply only to certain unique application. This sprinkler design would not be compatible in high pile storage .
I remember back in the days we had to cut that by hand on the vice. It s nice to see technology has made things easier but probably not as much fun as the old days
Yes we have a 6” to 8” manual pipe cutter onsite. If I don’t have the hydraulic cutter and groover available I will score the pipe with the manual cutter and then use a bandsaw to finish
@@NFPAJoe that sounds right. Let me introduce myself . Martin. Joe how s the union in Boston still a thing or not. In NYC not as strong as used to. Most shop are converted to non union
@@user-ny2zs8he3g Hey Martin. Thanks for the interest in the channel. Working on a new video now on obstructed/unobstructed construction should be a good one. Bostons unions are strong 💪. Work is looking good as far as I can see.
Informative.
Joe where you located mind asking . I was a install and repair guy for 10 years in Brooklyn Ny now doing design for 12 but live in Oregon still work for my NY shop
Heyy. Located in Boston Massachusetts
@@NFPAJoe Last time been there 6 months ago.
This distinguishing is always useful, good job Joe.
Thanks !
Joe a question for you , if you happen to know ,. I hear that black pipe in many jobs used on dry system. Galvanized only in ESFR jobs or big heads but I can't find anywhere that's describes specifically what's k factor size or at what point should use galvanized in dry system.
Heyy sorry for the late reply. So the option to use Galvanized pipe has nothing to do with code. It’s an option offered to have your sprinkler system last longer. During the sales process of having a sprinkler system installed you could choose to have black schedule 10 or 40. You could add a nitrogen system to help keep moisture out of the pipe. Or you could most commonly use galvanized pipe, and the only reason would be to have the pipe last longer before rotting out due to moisture.
@@NFPAJoe thank you so much brother
