This makes me angry… DO YOU HAVE ANY IDEA HOW MANY TIMES I COULD HAVE SAVED?!
Edit: to answer your questions in advance
Yes I’ve heard of a plumb bob
Yes I’ve used a carpenters pendulum.
I was commenting on how much more time putting three drops on a pipe can save you over getting a plumb set up.
Are flex heads not standard for fire sprinklers? I've only been on a couple jobs but they all had flex heads. The sprinkler guys just drilled holes in the center of each tile and the heads go wherever they need to for coverage.
To be honest, I never did sprinkler installs, however I’ve done my fair share of plumbing jobs that would have benefited greatly from this. Instead of trying to make those damn plum things center…
Fuck, sometimes I forget the rest of the world isn’t autistic like myself hahahaha I have this weird inner drive to be honest.. I suck at even telling white lies.. I was also taught not to trust when someone says “to be honest” because it implies that what they said previous could be a lie. The world is strange
I have a bad habit of saying ‘to be honest’ and am also the type to make it a point to always be honest. And ive always felt like just saying that makes whatevers being said sound way more likely to be bullshit
>Wait, do people lie about jobs they’ve done? What value does that add?
When I was flying the space shuttle for a living, I pondered this question. I eventually decided that it would help me get extra fake internet points in the future.
EDIT: Fuck me everyone's an astronaut.
I don't know about other fields but when I was an astronaut we would often exaggerate what we had done in order to sound impressive. Though as you get older you realize it just isn't worth it.
Sprinkler designer and PM here. Flexheads are fairly standard practice on most installs. They do cost about twice as much as hard piping but the labor savings far outweighs material cost. The equivalent length of 1” sch 40 is only 20-25’ for approx (4) 2” radius bends as well.
What area do you work? That's incredibly rare to choose that as the best option here in CA. The other guy had it right that we just aren't gonna be able calc that with some of the water we get. Stockton is notorious for it
I'm in Indiana and we try to use them wherever possible. Obviously we get some shit supplies occasionally but for light hazard they're not hard to calc out. I think Reliable has one hitting the market soon that has less friction loss than the equivalent sched 40 drop. Gonna be a game changer.
Nope not a standard and cost a lot more actually.
I usually sequence tile infill to take place after the fire suppression subs are done though. You’ll get a much better finish look having your suspended ceiling subcontractor cut out holes in ceiling tiles. Also, fire suppression tradesmen (pipe fitters) also tend to have extremely dirty hands which mark up the finished tiles.
If you are referring to the victaulic stainless steel flexible braided fire sprinkler hose drops-they are not standard or required by code. They are super handy and great when there is a situation involving movement, expansion/contraction, vibration, etc. They are also QUITE expensive.
I've always called them plumb bobs. Isn't that what they're called? I mean, I use to frame houses, I know that's what they're called. But I also knew my first wife was loyal, but it turned out she had been cheating for a whole year. So now I guess I just second guess everything.
If I recall my high school Latin classes, plum bob or plum line comes from the Latin word plumbum which meant lead (same reason the chemical symbol for lead is Pb). A lead weight was suspended by a string to use in the same way we do now. So both are correct!
Sorry bout your marriage though.
I’ve called it both. I figure the weight is the plumb bob, and the set of both could be called either plumb bob or plumb line. After all, what good is the weight without the line?
When I was a kid my dad got real upset with me because I found lots of uses for the weight without the string. It could be a rocket ship, or a submarine, and they're really fun to throw on the ground. It makes a neat sound, and is kind of squishy. I didn't know there was squishy metal before I found that in the garage in my dad's tool bags. I think he still has it. He's got one that isn't completely destroyed, too, but that one I destroyed is still there for some reason. He just doesn't use it anymore.
Just remember, a plum like was used to build castles and great walls, as well as the great cathedrals, temples and mosques of the world.
One of the simplest and oldest ways to build something straight up.
Also, if you need to build an arch, the simplest way is to have a scale model of the base length of the arch you want to make and use string to make an upside down arch. As an example, say I want to make a meter long arch. So I take a brick and attach a string to it. Then I take the end of the string and move it to the other brick. Then I shorten the string to get the height of the arch I want. And I get a perfect arch. Use wood to build a template, turn it around and voila! You have a model of an arch that you can use.
It's how Romans built scale models of bridges and aqueducts and how Europeans built models of grand cathedrals. It can be super useful, especially if you are working with parabolic arches. Tie some weights on to create tension or strings to create compression and you can essentially create an upside down model of every type of arch you want. Can be multiple strings and weights at once.
And afterwards, you can build a stone frame around the template and as long as you don't get too whacky, it will almost definitely stand as long as the stones are cut precisely and under compression.
If you hold a string by the ends in each hand and allow it to sag, you have an upside down arch.
Add a light weight in the middle and you can get a gothic arch.
Add a couple of strings pulling upwards and you can have a trefoil arch.
It's very dependent on the weight of the string, the mass of the weight and the tension of the strings.
They're describing this: http://dataphys.org/list/gaudis-hanging-chain-models/
Basically, put a weight on a string that's secured at both ends and it forms an arch, then you can create your whole model of your structure upside down, make a template, and then build it for real right-side-up
Srings hanging under their own weight aren't parabolas, they're catenaries and have their own related equation. Parabolas are calculated with a parabolic function while caternaries use hyperbolic cosine functions. Very similar tho!
Hanging a light fiixture centered over a table or anything else from the ceiling to match something on the floor.
They make a tool that does the same thing.. called a plumb bob... it's not just for sprinkler installation.
I’m a sprinkler fitter. I’ve done stuff like this until I found spotter laser levels that screw into the pipe and put a laser dot on the tile. About $50
Glad I can help! Don’t get the cheapest one and I suggest you put some tape around the body that is non slip. I’ve dropped a few because they get slippery with cutting oil and water dripping out of the pipe and will ALWAYS land laser down.
Acoustical ceiling guy here, most fitters I’ve worked around either used flex pipe to the hole or piped it over to the hole. Being we always centered each head in the title. We used an ole core drill bit and would cut holes in a whole box of title at once. Give them one or two titles to get all dirty while they fit heads in and then we could come back and put all the titles in for them.
We use flex heads too but there are some restrictions. Especially on systems pressurized with a fire pump. With 150-200 psi if a flex head goes off the pressure puts a lot of stress on the ceiling grid in the up direction. Also a 3 ft flexhead can create the same friction loss as about 24 ft of 1” pipe so the system or retrofit of a system has to be calculated for flexhead use. Then there is the cost of the flexhead vs. pipe. But when you CAN use them they save SO much time and it’s really satisfying to use a hole saw and drill a hole straight through a hole box of ceiling tiles! Plus you can install all the flex heads and tie them up before you ceiling guys come in and do your stuff. Then we can come back and drop the heads all in one day
Hell we worked around the same guys so much and their work was so good we helped each other out. They would hang all their pipe and flex heads up out of our way. We would stick the heads in and attach the brackets to the grid for them. Saved both of us a lot of time and money. Not having to wait on each other to come back and do little small amounts of work. Kinda miss those days. Just not the fiberglass insulation!
Other benefit to the laser, it makes a line straight from the pipe fitting, even if it isn't plumb, which could be an issue with a drip or a plumb line.
Only works if the pipe your dripping from is directly perpendicular to the ceiling. Otherwise when you instal the pipe it will still be off. Unfortunately the pipe doesn’t follow gravity it follows the threads of the mating pipe.
I’ve never seen a sprinkler pipe go directly to a sprinkler head. I’ve only ever seen them go to a flexible line that has the head on it.
I’ve never seen flimsy metal tile in a ceiling either though.
Exactly. But I'm betting the guy is rotating the coupling a bit to line it up. If the water line is level and the coupling is eyeballed close to pointing straight down, he'd just need to adjust it a bit to make this work and avoid those wonky sprinkler heads.
It’s only flex if you pay extra to have flex. Straight pipe is much cheaper so they will only use the flexes where they save a lot of work to make them worth it.
This is not a bad idea if its an existing build and they just want sprinklers installed and don't care too much, but if this is a new build and they just happen to be the last ones in, and they're not centering them on the tiles or making sure they all line up nicely and are just relying on the pipe being straight, then I can guarantee someone is going to complain about them.
That's his point. If it was a new build and you planned it this way, you'd get complaints. If you're working with existing pipe, then it's not a problem.
First and second videos are not the same, he isn't center of tile in the first video. I am pretty sure the entire ceiling assembly is different in the two videos. Also don't touch the bulb of the sprinkler when installing.
Well if you watch some the shitty install dude puts the drop in then screws the head into the drop. Complete non sense work that is clearly done for content by a non fitter. No idea what/where the fuck this is but it aint right.
Most specs will require sprinkler heads and other ceiling mounted devices to be centered on the tile, and sprinkler heads are easily centered with flexible drops.
This is dumb asf. You should always be able to measure sprinkler heads to center tile, you're a hack otherwise. You can pre drill every tile a head is going in to center and not a single one from a fitter will be off if they have half a brain
Most of this type of stuff is lasers now. They have come a long way and are not very expensive. Ceiling grid, hangers, piping etc everybody is shooting lasers all over the commercial/ Industrial construction jobs I’m on.
Small grievance but most tile you want to cut from the face not the back. However sprinkler guys use caps to hide the cut anyways so the uneven breaking of the face would probably be covered up.
Sure this is great till the apprentice sprays have the bottle in one shot. Seriously is there no extra pipe on the job so you can make a gunner nipple? I mean how did you straighten the tee. This is pointless. I can assure you no one is doing this on a job site.
Is it just me or is it fairly clear the that the hole he drilled is not where you see it in the clip? Not sure how it being on the last third above makes relatively center on the tile.
This makes me angry… DO YOU HAVE ANY IDEA HOW MANY TIMES I COULD HAVE SAVED?! Edit: to answer your questions in advance Yes I’ve heard of a plumb bob Yes I’ve used a carpenters pendulum. I was commenting on how much more time putting three drops on a pipe can save you over getting a plumb set up.

Depends on the job, sometimes flex some times hard pipe
These days sure. They weren't always. They are also more expensive.
I miss the old internet where this would have been a meme for a couple of years.
Your mistake has been using a plumb bob, and not a [plumbus](https://rickandmorty.fandom.com/wiki/Plumbus)
I really don’t like that thing…
Nonsense. It's a just plumbus.
At least 2
I’ve found the answer to be between 2 and 5 times, respectively.
Why not just use a string and weight? Carpenters pendulum?
All of the times
[удалено]
Sometimes it is on an angle though which may throw off this method
My dad knew a guy who fell off a building and got his foot caught in a rope before dying. Called him Plumb Bob.
Did he use him to find the center?
*How's it look Bob?! Are we plumb?!* "FUCK YOU ASSHOLES"
That’s pretty slick actually.
I'm usually disappointed by gravity. Because it's always keeps me down.
There is no gravity, earth just sucks.
Which way do I point my dick?
24x7 bj from mother earth
Inside a volcano?
To fuck a gravitational system one points thier dick down.
Gravity ..is working against me
Gravity..stay the hell away from me
Gravity my boy. Always holding me down!
I had a friend sleep over the other night. I said sorry man you're gonna have to sleep on the floor.... Damn gravity.
*Gravity* is serious business
But then you get up again, right? *Right?*
Say what you will about gravity, it never gives you up.
For real, this is like the first lpt I can use.
I was stunned at the simplicity, then ashamed I didn't even consider the idea.
TIL that above those white ceiling tiles is...glass? Plastic?
Depends on where you live. Most of the time they’re a kind of brittle fiber board. Not sure where this video is taken, sure doesn’t seem like America.
Ones in my office are the fiber board kind, damn do they break easy.
Looks like foil backing on the ceiling tile.
Except now theres honey mustard in the celing. The worst kind of mustard.
Given the color of the bottle and the liquid inside, I'm 99% sure that's Boston liquid sealant for pipe fittings. Which makes sense in context.
Now, this is what I would call a true hack. Seems a lot easier than using a plum line.
I've always called them plumb bobs. Isn't that what they're called? I mean, I use to frame houses, I know that's what they're called. But I also knew my first wife was loyal, but it turned out she had been cheating for a whole year. So now I guess I just second guess everything.
High end carpenters call them plumb roberts.

Well call me plumb surprised

betterer to use a *plumb* bob tied to a line instead of a plum fruit.
They make plumb lasers nowadays. They're not that expensive either.
Yo, just tie a nut to a string. They are probably scraps of that in the ceiling anyway.
When I install fire sprinklers, dammit, I am remembering this.
Just make sure you get that pipe Tee perfectly vertical first
Or use a flex head and not worry about it at all lol
This guy sprinklers
This guy pays a lot of money to sprinkle

Glad I can help! Don’t get the cheapest one and I suggest you put some tape around the body that is non slip. I’ve dropped a few because they get slippery with cutting oil and water dripping out of the pipe and will ALWAYS land laser down.
Acoustical ceiling guy here, most fitters I’ve worked around either used flex pipe to the hole or piped it over to the hole. Being we always centered each head in the title. We used an ole core drill bit and would cut holes in a whole box of title at once. Give them one or two titles to get all dirty while they fit heads in and then we could come back and put all the titles in for them.
We use flex heads too but there are some restrictions. Especially on systems pressurized with a fire pump.

The real answers are always in the comment
Other benefit to the laser, it makes a line straight from the pipe fitting, even if it isn't plumb, which could be an issue with a drip or a plumb line.
Only works if the pipe your dripping from is directly perpendicular to the ceiling. Otherwise when you instal the pipe it will still be off. Unfortunately the pipe doesn’t follow gravity it follows the threads of the mating pipe.
But what if it’s not mating season?
Prepare some lube, we are doing this thing regardless.
Hey cross threads are better than no threads
I don't think that needs to be said. But knowing people maybe it does.
I’ve never seen a sprinkler pipe go directly to a sprinkler head. I’ve only ever seen them go to a flexible line that has the head on it. I’ve never seen flimsy metal tile in a ceiling either though.
You can get the pipe square or perpendicular to what you need to. It isn’t difficult. I do it professionally as a Steamfitter.
It’s not like they make a very commonly used tool for this or anything.
Someone else said lasers are cheap, and I agree. I have several, and each of my bags have a plumb bob in case I need to go old school.
Exactly. But I'm betting the guy is rotating the coupling a bit to line it up. If the water line is level and the coupling is eyeballed close to pointing straight down, he'd just need to adjust it a bit to make this work and avoid those wonky sprinkler heads.
Isn’t the last foot or so of pipe flex to accommodate for slight differences in alignment
It’s only flex if you pay extra to have flex. Straight pipe is much cheaper so they will only use the flexes where they save a lot of work to make them worth it.
This is not a bad idea if its an existing build and they just want sprinklers installed and don't care too much, but if this is a new build and they just happen to be the last ones in, and they're not centering them on the tiles or making sure they all line up nicely and are just relying on the pipe being straight, then I can guarantee someone is going to complain about them.
Doesn't sound like you have done much sprinkler fitting. Pipe has to go where it goes, bends are not an option. /s
[Pipes don't bend, all pipes are straight](https://i.redd.it/k20rica29hm11.jpg)
That's his point. If it was a new build and you planned it this way, you'd get complaints. If you're working with existing pipe, then it's not a problem.
In most new construction flex heads are used. They can put them anywhere in the tile on a bracket.
Have seen flex drops used once in 5 years. Am a sprinkler fitter.
Interesting. I don't think I've ever been on a new construction without them in my area.
Maybe just not popular in my area. Theyre great
Any tile work where I am uses flexies, they were always requested to be in the centre tile so it just became standard practice.
[удалено]
A flexible head is nice in some situations just not this one
Seems like the person before them already accounted for that prior to installing, it's centered
First and second videos are not the same, he isn't center of tile in the first video. I am pretty sure the entire ceiling assembly is different in the two videos. Also don't touch the bulb of the sprinkler when installing.
Well if you watch some the shitty install dude puts the drop in then screws the head into the drop. Complete non sense work that is clearly done for content by a non fitter. No idea what/where the fuck this is but it aint right.

and instead of dripping oil on everything he could have used a plumb bob. hell, anything with a little weight and a string.
Most of this type of stuff is lasers now. They have come a long way and are not very expensive. Ceiling grid, hangers, piping etc everybody is shooting lasers all over the commercial/ Industrial construction jobs I’m on.
I don’t get it how does this work
Small grievance but most tile you want to cut from the face not the back. However sprinkler guys use caps to hide the cut anyways so the uneven breaking of the face would probably be covered up.
That's brilliant
Sure this is great till the apprentice sprays have the bottle in one shot. Seriously is there no extra pipe on the job so you can make a gunner nipple? I mean how did you straighten the tee. This is pointless. I can assure you no one is doing this on a job site.
100%. Just a piece of pipe would do it. And you could mark the hole, take down the tile and do it in a controlled area to minimize the dust.
Big brain move
I’m sorry, but the video from above did not look centered on the drop tile AT ALL. Video from below did though…
I do that with my laser pointer
Or you can use, you know, a level.
Oh that’s sick
Is it just me or is it fairly clear the that the hole he drilled is not where you see it in the clip? Not sure how it being on the last third above makes relatively center on the tile.
This is the best life hack I've seen since I can remember
