Your welcome!! 😎👍

Your welcome. And yes I always tell the truth when doing KZfaq. I don’t put it on KZfaq unless I can reference to NFPA 👍

Thank you. Yes my next video is on obstructions over 4 feet. I have a couple more videos I plan on making about obstructions.

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 👍

Thanks, will do! 😎👍

😎👍

I do plan on making more videos. I want to cover all the different style sprinkler system valves and fire pumps.

Thank you !

Thank you 😎👍

Your welcome ! 😎👍

Thank you!! I appreciate that and happy to hear 😎👍

Thanks ! Yes I have a membership with NFPA codes online!

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 !

No problem!

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 👍

Awesome, thank you!

Thank you !

Thank you 😎🤙

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

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.

Hahaaa 😎👍

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 [email protected]

@@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

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.

Heyy. Located in Boston Massachusetts

@@NFPAJoe Last time been there 6 months ago.

Thanks !

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

Hahaa have to watch out for the no response ! Yes the freezers and warehouses could go into ordinary hazard group 2 which would require the standard response. Thanks ! 😎🤙

@@NFPAJoe Thanks Joe , I started following you I am working freelance for my shop in Brooklyn NYC but myself live in Oregon for now. City has much simplified work than west coast construction of mostly combustible and all.
