Home Fire Sprinklers



in most parts of the country with the new codes you're now required to install a fire sprinkler system in a new home on today's episode I'm going to give you the basics of the fire sprinkler system or installing here I'm coming to you from a new house our company's building in a jurisdiction that requires fire sprinklers and I thought I'd use this house as a backdrop to tell you about the system so you see here the ceiling pipes that are orange these are the fire sprinklers for the house and each one of the heads in the house is going to cover approximately a 12 by 12 area so in this big master bedroom you'll see we actually have three heads in this room to cover properly the entire room now your smoke detectors in the house those are tied together so that when one smoke detector goes off they're all going to go off the fire sprinkler system on the other hand is controlled individually by each head and it's heat that's going to set these off and not smoke so don't worry about candles or burning fish on the stove none of that is going to set off your fire sprinkler system only the heat getting up to the proper temperature is going to do it let's take off this construction cover and see what this looks like now this is a concealed ahead so once the draw we'll get tongue and the contractor comes back to finish the system off your only thing you're going to see here is a metal disc that's about three inches in diameter to the ceiling all the sprinkler head is concealed in here and the system that makes these go off is pretty cool there's going to be a glass tube in here that has an alcohol in it that alcohol is temperature sensitive so when it gets to a hundred and fifty degrees that alcohol expands and breaks the glass tube the glass tube is holding a plug in place which holds back the water pressure and now that plug when it falls out is going to let that water flow and each individual head is going to cover about a 12 by 12 diameter area and be able to extinguish that fire they say that these sprinkler heads can put out on most fires in about 90 seconds or less so it's going to happen pretty quick the other thing I like about this system is that they're not interconnected meaning if this head goes off the whole house isn't going to go off only a head that reaches that temperature now if we had a raging fire in this room probably all three of these heads would go off but if we had a smaller fire where that fire was just in one room the rest of the house is not going to go off it has to get to that temperature at this individual head pretty cool hey I'll put a link in the description for a website if you want more information about this but don't be afraid of fire sprinkler systems they're pretty impressive systems they're in sawing millions of these worldwide very very reliable this is a system that's probably coming to a new home near you thanks for joining me we'll see you next time

    Do these always get ran over truss? What about when attic work needs to be preformed, its a accident waiting to happen, especially with a properly insulated attic

    That particular head DOES NOT have a the glass bulb or alcohol it actually has a a fusible link which that’s what that black thing is right above the deflector. Hopefully that system has a backflow and wayerflow indicator on it or your asking for some bigger issues.

    If a raging fire were to happen would the water pressure be able to keep up ?

    What about all the wiring above the sprinklers? Whats protecting the roof and everything above them?

    I'd be worried about the gluing. One of the failure points in CPVC is having excessive glue left on the pipe. The pipe in your video has visible glue drips, which weaken the pipe and can cause it to fail over time.

    Hey Matt, are you certified to even be touching the system or done your full research on the different systems?

    Good video, but you screwed up on the explanation with the glass tube containing alcohol. The sprinklers in your example have a metal fusible link that melts or softens and falls away, which is in place of the alcohol solution containing glass tubes in other systems.

    Already been asked but not adequately answered: how to ensure against accidental triggering? The answer is that they are recessed into the ceiling. But it doesn't look like the head is surrounded by anything structural… just plan on drywalling around that? That's not a lot of protection from the kid with the ball.
    Related question: are shut-off valves installed in easy to access locations to shut off the sprinkler quickly in the case of accidental trigger?

    For everyone using this as a diy resource….

    Do not
    paint the cpvc
    Get oil on it
    Get any type of solutions on it
    rest any other plastics on it
    Placw metals on it
    Use non FBC compliant products
    Use any fire caulks
    Use great stuff or red foam

    Hello Matt, As a retired firefighter I think this should be a standard that all 50 states and every county that all new homes be built with a home sprinkler system. As a home inspector I point out if the home has a fire sprinkler system and I note it. What state are you located in that you are building this home?

    I love it but damn if your house ever caught fire while you were away your house would be flooded and I am sure the water damage would cost just as much to replace everything. Sure it would be great for the neighborhood but it's an option that would weigh heavily on my mind as to whether or not it's a good investment.

    Has anyone done a cost-benefit analysis of these residential systems? The building codes keep adding stuff that is questionable.

    There are insurance companies that don't allow for sprinkler systems due to the water damage that is created. What the difference, your house destroyed by fire or water damage? Isn't this all about saving a life?

    At our condo community here in Connecticut, frozen and cracked plastic sprinkler piping has caused major damage and increased insurance premiums. Number of fires? Zero. I think it's over kill for single family residential buildings.
