"Every day when I go to school I see people trying to cut sprinklers with a reciprocating saw." -Firealarmdude5967 2022 Makes perfect sense, I see it at school all the time.
I came to this video because I want to clean the one in my apartment, but I'm afraid I'll set it off. I ended up staying to watch this guy take a batter, hammer, soccer ball, fire extinguisher, and a saw to a sprinkler. lmao. This is top notch quality, Mr. FireAlarmDude5967
Union Fitter here: it is still HIGHLY advised to be careful around them. Each head could be more fragile than the other so still avoid making contact with them. ALSO if you activate a sprinkler head you will not just flood the room it’s in. These are made to flow a LOT of water out of them and it will take an engineer or someone who runs the building a few minutes at least to get to a control valve of some sort to stop the flow of water to the head. You will flood not only your condo but the hall and more than likely the condos next to you. These systems usually sit over a hundred pounds of pressure so really high flow rate. Long story short: don’t touch them still lol
I wonder if the higher pressure in actual systems doesn't make the red vial actually more fragile than it was in the demo shown in this video. (Although I don't know what pressure it was but I guess it was lower than a commercial system).
That is an awesome video........I have worked in many industrial sites and have always wondered how tough these are. I am also surprised that there are not more cages. Great job!! DD
Thanks for the demos!! My experience is that the typical fire-sprinkler-system discharges I've run into has been during a construction project by either a strike by a boom lift/scissors lift by another trade (painters, drywallers, electricians) or a forklift moving loaded pallets in a warehouse situation and gets too high. Also had a client with a high-bay warehouse that stored furniture for their large furniture store. The high-bay warehouse would then fill customer orders from the storage racks. However a firm with very poor welders had put together the rack system (5-rows high) from a 2-row system that had been purchased from another storage firm that had ceased operations. The Fire Department receives a fire alarm and sends trucks but when they get there the reason the system activated was that the rack system had collapsed due to the poor welding. Due to the furniture load every row of the 5 rows had its own sprinkler line. That was $400,000 of damage back in 1990 which would be $1 million or so in damage today. Other than that, as you correctly point, out these fire sprinkler heads are very durable except for heat. Only surprise here was the coat hanger as I've went into rooms of friends/colleagues at a business convention and told them not to use those sidewall heads as coat hangers. Have never seen those sidewall heads discharge but have heard about it second hand.
Its not so much the hazzard of setting them off, but hanging anything (colthes hangers WITH clothes attached, or even Xmas decorations) will severely affect there response time, and there spray pattern , once activated
My school district replaced most sprinkler systems a few years ago. They are now flush mounted under white covers in the ceiling. The head pops down in the case of fire.
This would be concealed heads, not flush mounted. The covers fall (melt) off at a temperature less that the heads activation temp. The heads diffuser drops down when the cover falls off.
Wow much more tough than I would’ve expected those cages seem to fail pretty easily I see them fall off all the time I know you don’t have the set up for testing that so it couldn’t happen but i am curious to see how much force it takes to break a threaded joint on sprinkler pipe I once saw in a crawlspace a 4 inch sprinkler pipe where the ready rod had failed so there was about a 50 foot section of 4 inch pipe not supported and it was under a gym floor so when the gym was being used this thing would start moving up and down by about a foot at the end Great video though
Anybody who's lived in a college dorm has heard stories of people breaking a sprinkler head with something like a football and flooding their entire floor/every floor below them. Back in high school a guy accidentally broke one that was in the ceiling of the gym (about 30 feet in the air) after punting a basketball.
Our builder warned us about throwing balls near them. They got me paranoid AF. My son still practice throwing in the basement, and I get nervous on his high passes. This makes me feel a little better. I still think I'm going to put cages over them in the basement.
there was a student back in my high school days that set one off by getting his keys stuck and yanking on the lanyard. reportedly flooded that part of the school.
@@FireAlarmDude5967 i have a 2 pound buckeye ABC fire extinguisher that i have laying around aswell as an amerex b402. I could give them to you if necessary.
It would work the same way, but the spray pattern wouldn’t be as effective . Side and pendent sprinklers are designed to have a spray pattern that is ideal for their mounting position.
Sometimes the sprinklers are mounted on the wall. You jostled the coat hanger from that direction, but I feel like if you hung something on the glass bulb it would probably break.
I have a burning question (no pun intended) on sprinklers.. why have the dome under it.. wouldn’t take create a umbrella above the fire??? Seems counter intuitive
My washer is on the 2nd floor and vibrates my wall like crazy, I was worried the sprinklers will eventually blow up with all the shaking. After watching this crazy video, I guess I'm safe? 😀
1. You need to pump that sucker up to 140 PSI or so which is what you'll find in real life. 2. Clothes hangers don't go on vertical sprinklers, they go on horizontal ones. In hotels people mistake horizontal sprinkler heads for clothes hooks and that's where the whole issue with the signs originates. 3. If some day you take it up to 140 PSI, might as well keep going and see how far up you can take it before something bursts. Most heads are nominally rated at 175 PSI (though they'll probably go much further than that)
1) 140 PSI may be realistic pressure for a system but the point of the test is to test the durability of the heads, which is completely independent from the pressure 2) That applies to all heads. Those signs are near every head, ceiling and side. Either way, it doesn’t matter, because the point is to to test the durability, which is roughly the same for both heads. 3) Perhaps. Not sure how I’d get a head pressured that high
We were having Mexican officials visit our office in San Diego and one of my coworkers was moving a flag stand into the conference room by rolling the base at a slight angle. Only had a few inches to spare and he didn’t see the sprinkler head. Anyway, he hit it and it went off. (Don’t know if the metal eagle hit or what) The maintenance guy said it was discharging 100 gallons/minute. In no time we had several inches of water in the 1000 sq/ft conference room. Carpet ruined, drywall up a foot or so had to be cut out. Only silver lining is I HAD NOTHING to do with it. 😉
Well, with a k8 head and a pump with a 200 psi churn in a high rise, and right off a cross main, that's not the most implausible number, but most likely a bit lower.
100 GPM is a bit much for an office system. more like maybe up to 60 GPM max for that setting. A 100 GPM head is more for heavy hazard occupancies with large orifice heads.
The only way it will go off is if you hit the glass bit. Likewise if the room it is in is on fire once it reaches a certain temperature thats what triggers it.
Not fully true. If you make hard enough contact you can mess with the seat and it will start to leak. Not a lot of water BUT there is more than likely a hundred pounds of pressure behind the head so that’s a lot of faith to put in the glass to keep the head from going off.
You have to either be a drywaller or electrician with a piece of conduit or a lift to set it off… been hangin them bastards for 10 yrs… that’s the most common effective method.
The hanger one is meant for wall mounded heads not ceiling mounted heads reason being is the weight of whatever you’re possibly hanging can break the glass and you can even see that in the photo you provided, the sprinkler head is mounted to the wall.
I hate sprinklers they cauaed me so much ptsd I had to move out of my last apartment fire happen in apartment above me 3 floors above me n the sprinklers went off in that apartment plus the fireman spraying water from there hoses i got flooded out list everything i owned n i had nowhere to live for 2 months i had to couch surf wasnt fun they do more damage than they are worth having
@FireAlarmDude5967 yeah but the fire was 3 floors above me n water from sprinklers and firemen damaged mine n 2 other apartments that was below the apartment with the fire
That's the joy of gravity. Water will flow downwards and your unit was below the fire zone. Nothing can be done about that. As mentioned, either fire damage or water damage. If the firefighters were not using water, the fire would spread. How else are they expected to put out the fire?
Just had a horror show at one of my shops last week, movers hit the sprinkler, my store flooded water went to both neighbors, I'm fuckd thank God I have insurance , movers don't.....
This is so bad to show. Don’t be doing any of this. I know it’s to show how they aren’t that easy to break. But most of the things he’s shown that doesn’t break it. It’s because he’s not hitting it hard. He’s not proving anything in this video.
You missed the point of the video entirely. The point of the video is not to say that you should hit fire sprinklers. The point is to test how hard you have to hit a sprinkler head to set it off. Anyone with half a brain knows to not intentionally hit sprinkler heads.

right! I've been terrified! So glad it's all good
Thanks bud. Just moved into an apartment with these everywhere. This vid gives me peace of mind lol
Love the sprinkler videos man 👍
Thank you for this, I feel better about the sprinklers in my condo!

Yeah but you couldn't break the glass with your finger. It would take something a lot heavier like a hammer.
They should be in prison they're going to get worse as criminals
@@AgentOffice That's a little extreme, you must live in a gated community 😂😂😂
If the hang on it the sprinkler may get pulled down and have air tight and glass may break over air preassure

Residential systems are normally around (as low as 7 psi) to 30 psi. Commercial systems can be as high as 175 psi.

Not only your room is wet, you will get the whole hotel evacuated . It will set off the fire alarm.
Correct
Just a random question. Could you compare buckeye and amerex fire extinguishers?
Fire extinguishers are expensive so perhaps one day but unfortunately not likely unless someone else sends them for testing purposes
@@FireAlarmDude5967 i have a 2 pound buckeye ABC fire extinguisher that i have laying around aswell as an amerex b402. I could give them to you if necessary.

Request: fire alarm going off at South Shore Plaza Braintree Massachusetts
What is the water PSI in the pipeline?
Not very high. Just enough for the purpose of demonstration
I have an idea for a future video, what happens if you put a pendent sprinkler on the wall?
Perhaps
Or even a sidewall sprinkler head on the ceiling
It would work the same way, but the spray pattern wouldn’t be as effective . Side and pendent sprinklers are designed to have a spray pattern that is ideal for their mounting position.
Essential answerrs
What is the best way to catch the water if a fire sprinkler goes off accidentally? Do they make anything for this?
No way unfortunately. A sprinkler discharges so much water that any bucket will be quickly overfilled.
You can't contain all of the water but they do make sprinkler stoppers that can be wedged into the head in case they are activated.
I've seen videos where teachers accidentally set off the sprinkler in a classroom, setting off the fire alarm as a result.
Sometimes the sprinklers are mounted on the wall. You jostled the coat hanger from that direction, but I feel like if you hung something on the glass bulb it would probably break.
I mean I did hang something with the hanger holding onto the glass. Weight was on the glass anyways for the most part
