- All new homes in California will now be built with fire sprinklers. To answer people's questions California State Fire Marshal Tonya Hoover explains how sprinklers work and how easy they are to maintain. Video provided courtesy of the Home Fire Sprinkler Coalition HomeFireSprinkler.org.
Great video, I was a building engineer for 30 years and we did fire system test annually. It was interesting how people believed movies when it came to sprinklers and we had to explain that it would cause more damage if the sprinklers on another floor went off when there was no fire there. Thank you so much for explaining this so clearly and concisely.
thanks for your support ^^
thanks for this video it helped me and my family survive
Very informative
I am a fire alarm enthusiast and I want a sprinkler system so bad LOL!
Knock thine self out. I'm not saying they don't work. Just don't be surprised if they don't work as advertised under many conditions.
Chris Gordon they work very well.
Things that are needed.
In existing homes, a dry system installed in the ceiling of the top floor with a supply coming off of an upstairs bathroom. A wall mounted system for the first floor that can be slid up inside the walls of a room from the basement to a small hole toward the top of the wall.
For any structure, a timing system that will shut off the flow in a set number of seconds and keep it off unless the temperature rises again. This will prevent unnecessary water damage.
There should be different or adjustable nozzles based on the furnishings inside any given room so the pattern will be the most effective.
The system you described is rarely used due to the exorbitant cost and maintenance requirements.
One good thing that California did!
@demo man from my code book (i am a licensed sprinkler fitter and do classes for all updated codes,and revisions of codes ) it reads that any piping that can or will be subjected to any freezing temperature must either be a dry system or antifreeze i.e. glycol or glycerine.i live and work in ohio so we see this frequently with freezing temps and people laying insulation over pipe or heat tape.And we go through and point it out to the customer in nfpa.
NFPA 13D A.9.1.1
Every single house should have this. I mean a lot of department stores have these sprinklers so homes should have them to. This should be a law in every state and these sprinklers should be in every apartment building plus this law should apply to every state+country.
They are NOT the same systems. Not even close. What you find in a Department Store or a shopping mall is miles ahead of these cheapo home systems that were forced on us by the plastic pipe manufacturers.
You can't beat the safety. I am a retired fire inspector and trust me, if there is ever a fire in your house, which is more common than you may realize, this is the way to go. Think of it this way. If you are in a home without fire sprinklers, and a fire occurs, NOTHING is there to put out the fire and you need to get out somehow around the fire. Meanwhile, the fire continues to grow until the fire fighters arrive, which can take up to 15 minutes if you are far away from a fire department or all local departments are super busy at that time. This puts out the fire very quickly, with minimal water damage, whereas the fire fighter hoses will spray in huge amounts of water, damaging everything in their path.
The Grenfell Tower fire in london... if there was sprinklers fitted, the fire would have been contained to one room. there was no sprinkler system and multiple people are now dead.
There is a more effective way than fire sprinklers called automist by plumis automist can extinguish a Fire 16 to 20 feet away one automist spray head can cover an entire room automist uses 90%less water then fire sprinklers automist automatically activates with an second of the starting fire
Oh please. The only way that Fire Sprinklers would work in that London fire was if the building had been engineered for the correct flow and the correct booster pumps installed to keep the pressure up on the upper floors.
The twin towers were al sprinkled on 9/11/01. They didn't put the fires out because the booster pumps failed to keep the water pressure up. And if something happens to the electricity, the pumps don't come on.
Its just something else that you pay big bucks that cost even more bucks when they schytte the bed.
Soo.."the only way that Fire Sprinklers would work in that London fire was if the building had been engineered for the correct flow and the correct booster pumps installed to keep the pressure up on the upper floors"
Try reading NFPA 20 its the standard for stationary pumps for fire protection. It will tell you exactly how to size the fire pump so you can meet full system demand in any part of any building.
If you knew anything about sprinklers you would know they are designed for a fire that starts in a building in one room and for a specific hazard most likely "light hazard" as they were offices. when the plane crashed into the building it most likely set hundreds of heads off sheared off risers that fed the systems and contained jet fuel which would be an "extra high hazard" which on most cases would require a foam system which are found in air craft hangers not office buildings! Chris Gordon you have no idea what your talking about.
Sprinkler protection should be mandated for ALL new residential construction. It saves money, reduces damage from water, and reduces insurance premiums.

3:29 what is a water hammer, and what can they do to your valve and/or piping network?
When the valve is shut too fast the water flow comes to a dead stop causing like a shock wave through the system and can cause damages if the pressures great enough .That's the "bang" you hear after shuting off water in a fast manner.
when do a water flow test does that flash the water in the fire sprinker
No it's always running. Doing a flow test opens up the train valve causing all the water to flow out of it and outside
Is there a backflow preventer on fire sprinkler system.
The backflow preventer is at the water meter where all water must pass to enter the home.
there so many videos recommending and showing how to turn off the water to the home while on vacation and they do not understand this shuts off the fire sprInkler system to the home for emergencies. I wish there a way to do both. Shutoff water to main home but leave the fire sprInkler water line active.
She's beautiful. I really like the way she talks.
You creep
I wonder when it will be mandatory in Ontario to have a house sprinkler system?
Hopefully soon everywhere
A Commentator and homes will have fire exit signs as well?
Builders are preventing this from becoming mandatory in all new residential construction due to cost. Of course, lives of their customers don’t matter as much as cost.
How manu hours to use testing for 1flr for fire protection springkler
How many hours to use testing for 1st flr for fire protection system
what they need now is lower curbs and steps mandate so that no one gets hurt or killed falling off steps shouldnt cost more than a few thousand dollars but will be worth it in lives saved.
How are these systems monitored, or are they monitored at all?
Monitored by a security monitoring company. Like ADT or SEI. Similar to the way a home security system is monitored. Any alarm on the system will alert the central station of the monitoring company
Pipefitter lobyists in action
More like the plastic pipe and fittings manufacturers in action. Try taking a 50 degree anti-freeze solution and put it in the freezer. It freezes to slush. Water won't flow. You need approved backflow valves. It has to be properly sized for the load. If you have a 3/4" Poly Water Service, it will NOT ever handle a fire sprinkler. If you put Anti=Freeze in a potable water system, it must be separated with a backflow. Even the Non-Toxic stuff.
have been looking for sprinkler for my house built in 1935
they can be done in attics
Skiing Canada Sprinklers ONLY inside of attic, therefore no holes drilled through ceiling?
Had been wondering if fire extinguishers could be mounted somehow and skip running pipes
hahaha some of the pipes werent glued when they made this video.
That is suppose to be the fire riser lol
Maintenance free? Yeah right. I manage 45 homes with sprinklers and at any given time at least one has some issue...
Examples of problems
I left the test valve open my naibors yard flooded
155° fire sprinkler spray water.
fire sprinkler' fire alarm and a smoke alarm
I wish my house would have a sprinkler system fire alarm system and mass notification system
Install it.
Lmao sprinklers have basically been standard in all commercial buildings since the 1970s but everyone has a fucking fit when they’re being introduced to houses on a major scale 40 years later.
I wish Florida mandated this, fires are too common, with all the forest fires hopefully there will be some changes.
Interior fire sprinklers won't protect a house from a forest fire.
I disabled my system. That is right, my house is not protected by any system.
Why? That's such a bizarre thing to do, and it's even stranger to brag about it online. Hopefully your insurance company doesn't find out.
Because lol
Smart just wait until your insurance company finds out
the pipe in the attic with R20 over it would never fly around here in Canada it would split wide open in the first winter lol
That was a great video I hope that she was paid very well however. What was not brought up was the real possibility of a fire sprinkler system failing in your home. I am recently witness the results of CPVC pipe failure in a home. The damage is approaching 1/2 million dollars. This is a well constructed house with lots of sheet rock and lots of fire the smoke dectors. There is really no real safety checking that could be done with these CPVC systems. Home owner be wear.
Ed Shelden Residential fire sprinklers preferably should be connected to an alarm system that is tied in with a central monitoring station. That may not be required but it is a good idea. At a minimum, there should be a bell that sounds when water flows in the sprinkler system. Undetected water leaks from any type of piping or plumbing fixture can potentially cause massive water damage unless someone is alerted to the problem immediately. I think that if the sprinklers are mandated by code, then an alerting device should be part of that mandate.
There are ways to safety check these systems. if you hired a licensed installer the system should have been tested to 200 PSI to check for any system failures before the house was finished.
A common issue that is not finally starting to get some attention is the reaction of cpvc pipes that have been in contact with flexible wires that contain plasticizer. The chemicals in the wire jacket that allow it to be soft and pliable have a chemical reaction with cpvc pipe that causes it to crack and fail under pressure. Saying things like, 'buyer beware when installing sprinklers' is ridiculous thinking and is no different than saying 'buyer beware when installing plumbing. Pipes could fail and damage your house'
Serious Karen hair
BÖR VARA STANDARD
It's also 70 thousand dollars to have a professional to install them..
No it is not. Also, nice username...
Lol more like 5-7 grand and 2 days work
the problem with this video is the plastic pipe should never be anywhere that fire could get to it. they have it exposed in this video
CPVC sprinkler pipe flashes at 900F meaning it cannot contribute to flashover, and it cannot sustain combustion itself meaning it cannot be the source of a fire.
The cost of these sprinkler systems FAR outweigh the benefits. Most insurance companies give a discount, but it’s a single digit one. You would have to live there 10 years before the discount will equal the system cost.
Yes? Most people that own homes end up living their whole lives there?
@@wallywalt505 - NO, very few people stay in the same home more than a few years, be it a rental or ownership. I lost count on how many places I have lived in 60 years.
its against nfpa 13r to insulate any sprinkler pipe in any aplication,code ahj cannot say lay insulation over pipe code states that if the system could be subject to freezing temperatures a dry system must be installed i think its funny a fire prevention officer can misinform a customer, granted it is California
+Colin Law it all depends on where you live, we have wet systems with exposed pipes but its never below freezing for more then a few hours. loading docks are a good example.
Your wrong about that. I'm in the sprinklerfitters Union in Pittsburgh and yes you can insulate wet systems in an area subject to freezing whether it be residential or commercial. The job I'm on now has our 8 and 6 inch main feeds running through a parking garage from the curb and there all insulated until they hit the stairwell to feed the standpipe. So I beg the differ on that one. Also on another note. You can throw that nfpa 13 book out the window in some jurisdictions cause the ahj has the ultimate say so no matter what nfpa says.
Nfpa is not law. It’s recommendations. The ahj does not have to follow it to the letter or at all if they choose not to
It was arsonists
60 seconds is too long. 20 seconds is best
That system doesn't have a backflow? That looks wrong... Why is the flow switch buried in the wall like that? This looks like some bunk ass california work
That isn’t “for people’s safety” that’s for the fire sprinkler company’s wallet.
Don’t let people who sell safety devices tell you what you NEED.
How are these systems monitored, or are they monitored at all?
Like smoke alarms, they don't need monitoring because they are automatic systems.
Every single house should have this. I mean a lot of department stores have these sprinklers so homes should have them to. This should be a law in every state and these sprinklers should be in every apartment building plus this law should apply to every state+country.
Absolutely! We should tell people what to eat too bc some foods are very dangerous over time! We should make all goods things a law and all bad things should be illegal! Nobody should make their own decisions, we should just give all our money and decision making to those who know best!
***** Frenchfries agree on that one, at least for newer structures, so many structures would be saved if they had sprinklers
watch out, you can be all for anything but you forget that there is consequences or pro and con's to each situation. In a multi-family home, yes it should be considered since people can be careless with fire and appliances. In a single family home, it should be left up to the home owner who wants such a system because not everyone can afford to upkeep these systems when they break, they cost a lot upfront and repairs can cost a ton to meet existing code changes. Its a nice necessity but insurance will cover the damages from a fire including water damage. Life can't be replaced but it should be left up to the home owner because you have to value people wishes in a free society even if they go against the community ideals along as its not breaking the law.
There is a more effective way than fire sprinklers called automist by plumis automist is a wall mounted fire suppression system automist can extinguish a fire 16 to 20 feet away one automist spray head can cover an entire room automist can tackle dangerous fires useing 90% less water than fire sprinklers automist activates with an seconds of a starting fire go to google, safari or CZcams and look up plumis automist
Jordanram@optonline.net Frenchfries These are nice to have but making it the law everywhere is a little far. This law was created by the people who install these sprinkler systems.
