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.

The system you described is rarely used due to the exorbitant cost and maintenance requirements.

NFPA 13D A.9.1.1

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.

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.

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.

You creep

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

The backflow preventer is at the water meter where all water must pass to enter the home.

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 many hours to use testing for 1st flr for fire protection system

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

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

Examples of problems

That is suppose to be the fire riser lol

Interior fire sprinklers won't protect a house from a forest fire.

Install it.

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'

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.

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

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.

+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

No it is not. Also, nice username...

Lol more like 5-7 grand and 2 days work

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.

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 KZfaq 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.

Like smoke alarms, they don't need monitoring because they are automatic systems.
