In some high risk areas this does happen. However, in the movies they usually all go off in an office building. This is not a high risk area.

blue ferral in correct. The only time that will happen is when it is an open head system aka deluge.

+Scott Hixson very welcome!

What are you talking about? He slipped down the stairs and his face specifically his eye hit the door knob.

What city do you install this? Looking for an installer in the San Antonio TX area?

briancnc 90% yes and should be monitored

The shut off is located in the street. To turn it off, you must turn water off to the house.

Yes

When there ran above the truss....😰🔫

Hey buddy- I've been in the fire industry for 13 years. You cannot build your own fire sprinkler system. It has to have proper water pressure calculations that comes from a engineer when it's designed. These have to go through the city for approved plans by the fire marshal and after The Install you must do a final test to get the city to give approved inspection results ..

The opening up and subsequent repair of the drywall will be likely be very expensive as well, plus you will likely want to drape off the area where the sprinkler lines and heads will be so the drywall dust is kept to a minimum, and there will be a lot of it.

mpharr2 Keep an eye on the water for gunk and cloudy. Should be cycled 1/3 to half once a year. Clorine keeps it algae free. Eye on float for sediment buildup.

Only Md and Ca

They did? NFPA 13D is literally designed to make them as affordable as possible. Closet, bathroom, covered porch, and garage head omission, attic omission, backflow omission, audible alarm omission, FDC omission, remote test drain omission, monitoring and inspection omission, plastic pipe, low design flow, etc. And to top it off, sprinklers can even be completely connected to the domestic system and use PEX. I don't know how you could make it less relaxed. What would proliferate them is production home builders caring more about people dying than $1/sq ft. Instead, they spent that money lobbying for sprinkler ordinances to be outlawed in most states. Fire departments in ban states can also step up and push for them more.

​@@ironmatic1 I also think that average homeowners need to understand how incredibly effective they are. People underestimate the risk, and don't understand the reward. Not to mention, the chance that you could save the structure and significantly limit water and smoke damage... All it takes is working one fire with a fatality to decide they might have been better off with a sprinkler system.

Cut and replace

Your fire sprinklers deviate from your water supply before your house water shut off. That’s why it didn’t shut ur sprinklers off. You also cannot repair your own system. Fire sprinklers are NOT a DIY. You MUST hire a state licensed sprinkler contractor and get it inspected by a fire marshall.

Lol true

Why do visible/exessive glue is a bad thing?

That's why we have an electrical code, and you should never cut corners in many if not all trades. Safety 1st. Your shitty wire installation today can be death and destruction tomorrow. Do a good job always xD

Areas that pipes may freeze sure :) Not necessary in most residential homes around the world.

Neil Heuer No.

It's called a water flow alarm and yes you can install one. Some jurisdictions may even require it, but I'm not sure.

Residential sprinklers typically have a 120v bell for sprinkler waterflow. It would also be possible to connect it to the security (residential, doubling as fire) panel.

ellsworth It continues until the fire department turns the system off.

You can still burn stuff in the kitchen, have candles, crank the heat. Sprinklers don't care until a fire starts to become life-threatening They typically open at 155F - in a house fire, that's "155 and rising, the furniture is about to flash over." Those conditions will kill you if you don't immediately escape or get water spray to knock down the heat. If a sprinkler opens in a fire you should get out and let the fire department "overhaul" it before going back in. The only exception I see is if you live way out in the country. 155 might be too sensitive for a sauna or sun-room. 155 steady and dry is, well, it's not inhabitable but it can be survived indefinitely with enough water and salt. But residential rooms shouldn't get that hot. Country or town, it's a good idea to have clamps and know how to shut the system off so you can deal with accidents related to wild kids or overenthusiastic DIY projects. It's pretty easy to clamp a head closed with the right tool. Finally, insurance companies are happy to pay for accidental sprinkler damage. They've run the numbers and sprinklers save them buckets of money.

control valve

The city shut off in the street. They are connected directly to the main water, so it always will receive pressure.

They are recessed into the ceiling, with a plastic cap covering it. Yes. Kid need to be careful with their balls, is it will still trigger them. I was raised as a child in a townhome with sprinklers. It was a very boring childhood, as EVERY SINGLE ROOM HAD THEM and a couple did accidentally get triggered while living there.

No, not at all. The cover just makes it look pretty. You can just tighten it until it is flush

they run til the fire dept turns of the water supply.

off*

Well, instead of fire damage you have water damage!

Well, fires grow exponentially. That water will be flowing from the sprinklers a steady rate. Also, they do use water to put out the fire. A lot of water. Small hoses flow 150 gallons per minute. How far is your nearest fire station. A fire in a small trash can can extend to your whole house in 15 minutes.

Aside from using a shut-off valve, firefighters typically have wedges available which can be stacked together to block the flow of water from the sprinkler head.

RickMakes yes needs to be in conditioned space. If you are going to install in those areas then attic will need to be insulated to be part of the conditioned space.

some commercial systems are pressurized with air so no chance of freezing. When the tube breaks the air rushes out followed by the water.

Thanks for the help. MR

Cpvc can not be pressurized. It pops real easy. Verticle rises up walls to HSW for top floors.

I like the air idea would solve corrosion issue in metal lines as well

No.

depends on the system you have all of them can be shut of manually tho

Ha! No. Wish it was a better story. I tripped on a lego set in the middle of the night and nailed a dresser with my face. OOPH!

Been there, Done that!

Should be wearing your PPE most accidents and injuries occur in that family residence - and you're taking this ribbing very well too. Heal quick to end it all.

I swear the military should use those darn things. Lego's are the death of human feet.

Matt Risinger lol kids

We used a specific sub who only does Fire Sprinklers for this project. I'm not sure if PEX can be used actually. Anyone else know?

NFPA 13D covers residential single and two family dwellings. According to this PDF PEX is ok to use. plasticpipe.org/pdf/pex-plumbing-sprinklerapplications-01-17-2013.pdf

scroll down to slide 8.

Wow thanks for the info ill probably be doing this

Hmmm What size of pex pipe could a person use

Whoop whoop

No they don’t leak unless forcibly damaged.

In commercial buildings, they have a solution to keep pressure to the sprinklers with a lot of heads are activated. Those pipes under the “FDC” signs (Fire Department Connection) are for the fire department to hook a water supply into the sprinkler system.

@Jujuju the sprinklers would be raging then yes?

No, the glass is recessed into the ceiling. The only thing that will show at the ceiling is a metal round disk. Good question! Matt

Matt Risinger usually these concealed heads dont have glass bulbs..they have a fusable element.. not picking faults.. its a good video, just advising

The round disk is expelled by the water pressure when the head is triggered? Is it decoratively finished or does the painter finish it? And if the sprinkler is triggered does it terminate once the fire is quelled or continue until the fire service shuts the sytem down ( water damage mitigation)?

There are smart Fire Suppression system in development mostly in the U.K. The new systems use infrared sensors to aim a high pressure atomized water spray. This type of sprinkler can extinguish large fires with much less water. Without getting all nerdy about water the easy way to think of this is the smaller water spray the more heat is absorbed, and very shortly the fire spred is stopped and extinguishment is accomplished. Some system are even using the infrared sensors to halt water flow. As to water supply the piping can be a thermal plastic such as BlazeMaster. This is all covered by NFPA 13

@ Don The concealed head cover "disk" is also heat sensitive and usually 15 degrees below the activation temp. 155 head with a 135 cover. The cover will drop, the deflector will follow then the fusible link will snap at 155 and water will rush out. Do not paint the cover as it is against code. Its also stamped on it reading do not paint. You can get any custom color or finish, wood grain finish if needed too.

A lot less of a flood then if the fire trucks came and used their hoses…

The last time I went through training thats what I was told... but that was 15 years ago...

It's hard to put a price tag on your families life...

It's like $1 per square foot, compared to the cost of home construction it should be a very minor cost.

They can retrofit for about $5-$6K. In a brand new stick-built house, it’s starts at $3K.

bensyer The guy that puts the glass bulb into the fusible link conc head... Prob even a black bulb painted red.

ilike... This is what I was aluding to with my question. So.... OK. Now that you know these things, and are forewarned, what are the alternatives? Clearly a benefit of the water sprinkler approach is a near instantaneous stopping of the fire, and thus 'saving' precious possessions from the ravages of that fire. But the ravages of water may be just as destructive. So how do you squelch the water once the fire is gone?

The short answer is that there is no real solution to putting out a fire in a residential setting. The dry type systems are not designed for general use. ANSUL systems are used in kitchen settings all the time, but wouldn't be practical for a whole house. A Halon system is pretty much only use for sensitive areas without much personnel because it eats up all the oxygen in a space almost immediately. Once a wet sprinkler goes off, it is an open water tap until someone turns off the utility; all that water either has to be either swept or pumped from the house. I have never seen a "smart" wet sprinkler system (but they may exist). It is really a "pick your poison" situation. There is no way to win. The sprinklers would prevent the spread of the fire but destroy everything below a certain level. Also, sprinklers take high temperatures to activate which means the wire will be quite large before it activates; a decent amount of flammables will already be engulfed in flames. A wet sprinkler system is not meant to save things inside of a space but only to save the overall structure and to keep fire from spreading. It is exclusively there to prevent a bigger catastrophe. The best option if you have a large collection of extremely valuable stuff is to keep it off the floor in environmentally resistant containers in a single room with a large floor drain then install a wet or dry fire suppression system. That way if things ever do catch fire, at least you have a drain that will evacuate much of the fire suppressant and keep the property damage to a minimum. For most, that is impractical and expensive.

Now we are going to start building waterproof ontop of fireproof construction?

Stagnant water, eh? I wouldn't care if it put out the fire with piss. Fires consume buildings quickly.

It won't save belongings or houses, but it could save lives, especially for people in rural settings where the fire department may have a 20+ minute response time.

Shawn Mazurk insurance companies can't override building code. As jurisdictions adopt the latest version of code, these will be required by law. As for damages, water damage to a single room is still far less damage than the whole building being destroyed by fire. A $20,000 insurance claim is much better than a $200,000 or $2,000,000.

They just won't get as many customers?

Do they also not allow for upstairs bathrooms?

My insurance company gave me a discount on my premium for having a sprinkler system in the house I owned...

There are 75% more insurance companies that will actually discount you for having it. Much less damage from one sprinkler deployment versus a fire truck destroying ur whole house with giant uncontrolled hoses

well in the city hes working in its required. lol

@@resqjason2 I’m not saying they aren’t required I’m just saying in homes that are in residential areas such as suburban or rule areas they are not exactly needed but apartment buildings yes

flatswing also, it was a fusible link he referenced. How does the glass get put in.....? Ha

He was wrong. No one should place a glass tube in the head. There are different models. In the video, concealed sprinkler head’s model does not contain a thermobulb. Instead of a thermobulb, there is a metal piece that will move and let the water flow in case of water.

Read the blaze master and lubrizol web site first

For everyone using this as a diy resource Do not install a fire sprinkler system yourself

You also forgot do not DIY fire sprinklers.

John Boccuzzi Claim it to bad cheap installation and shoddy tradesmen.

Well there is a reason you need to keep the building at/above 40°C... We rarely see freeze ups in our systems

How much smoke and fire damage do you think is going to occur before the fire department gets there if you don't have sprinklers to put it out quickly? And do you think the firefighters are going to use less water by the time they get there then the sprinkler would? Of course they won't - they're going to cause a lot more water damage. Come on, think about it...

You can put a flow alarm and monitor it through your security system if you want.

I was terrified of them and fire alarms and anything related to them since a young boy. Not sure why. The fear of sudden things i suppose. Especially loud forceful sudden things. I did lots of research as an adult to learn about them and now i have a townhouse that is fully sprinkled and i could care less. Fire alarms go off at my work often and it doesn’t even phase me anymore
