I've been a sprinkler fitter for 22 years and I have many years in the fire service as a volunteer firefighter. I have replaced the sprinkler head after a fire and I am always impressed with how little damage there is. The residents are often complaining about the water damage, but I know that is because they don't understand how much fire and smoke damage there would have been without them. Plus the fire department would have to use far more water to put out the fire if there are not sprinklers so you have the water damage either way. The tenants are usually back in the other units by the time I get there. I have witnessed the lives and property saved many times. I have also witnessed the water damage from accidental discharge due to human error (people like to hang clothes hangers on them in hotels). With everything I know about them, I retrofitted them into my 100 year old house. However, I do not agree with codes that force you to install them into a single family residence. I think there should be information given to the owner about fire sprinklers and how fast a fire can spread without sprinklers and let them decide. Do I want to cut 6K from the landscaping or flooring budget for now and install fire sprinklers. Or roll the dice that a fire won't happen to me. I get that it is different since you are flipping the house and may not have a buyer who can make this choice. My opinion is always less government. I feel your pain being forced to do this. P.S. I did a water tank and pump for my house because it was cheaper than bringing in a bigger water service. The downside is they take up space and you have more that could fail.
Chiming in here (a few months late) I definitely do see the benefit in fire sprinklers as an over all. I think I was being a facetious that may not have came across as intended. But I will always agree with less government overreach.
The problem I have is I am in the country . My system MUST #1 have a storage tank and aux pump. #2 i will be using PEXA , integrated into domestic cold water system. #3 the system will be post initial build in a MODULAR HOME. Finding people qualified to design domestic water integrated fire sprinkler system in North Carolina is near imposable , finding one who will work with a home owner is more difficult
if you have children, they are priceless. i would be very happy and not even complain if my house was flooded during a fire but my kids were safe because of the sprinkler system.
This system saved my two young daughters lives yes there was water damage but the insurance paid for that and my daughters lived not sure why this guy feels they are a waste of time.
That's the point! They save lives, saving the house is secondary. The cost to fix water damage is very minimal most of the time. I have 40 years of paid fire department experience and fixing a little water damage is cheap compared to replacing the whole house.
So, you don't want a flood if there is a fire? Then you CERTAINLY want sprinklers. You generally only have 1 sprinkler head deploy to contain the fire, maybe 2. Each head puts out 13 GPM worth of water (typically) compared to the 300+ GPM a fire hose would use from a truck/hydrant. In a 13D (one or two family dwelling unit) sprinkler application like this, the job of the sprinklers is to give the occupants a chance to get out. Average fire department response time with a water truck (not aid car) is about 4-6 minutes. With new, lightweight construction materials and furnishings the time for a residential home to reach flashover (the absolute point where survivability is zero) is under 2 minutes. With sprinklers, 85% of the time a residential system will contain and EXTINGUISH the fire. Thus keeping that pesky fire hose from REALLY flooding your home. You are also more likely to be able to stay in your home or return to it within 48 hours if sprinklers are used to contain or extinguish the fire as it contains it to that single room source. You also get an insurance discount which over the life of a 30 year mortgage will easily pay off your $6k cost on the system in this instance. I could go on and on, but it would be worth your while to reconsider your viewpoint/attitude to this "useless" system. I hope they never ever have to be used, but if they do it is the best shot most folks have for getting out of their homes in time.
Can confirm. Had a friend who had a small kitchen fire that would have been put out by a fire sprinkler system. Instead, the fire Dept. dumped hundreds of gallons of water that ruined the entire kitchen and basement with water damage.
I think maybe our sarcasm and jokes were taken a bit seriously here. Eddy and I both don’t have much experience with fire sprinklers but we’re just being a bit bratty about having to spend a significant amount of money for fire sprinklers (which ended up being way more than the $6k all things considered).
@@michaelraymond2546 Misting systems are for very specific system requirements. These are not designed or priced for residential systems and cost more to install due to the misting nozzle type and construction. Again, a standard 13D sprinkler system uses no more than 13GPM so it is already far far less than a fire hose or even a garden hose in some instances.
I get it... Sprinklers are NOT cheap, and therefore not for everyone or every budget, BUT... For anyone to say they are "useless" or even that they "don't understand them" is baffling to me. The water that puts out a fire can come in the form of thousands of gallons from a fireman's hose, or it can come in a more controlled manner from within the house. You can settle for more fire damage becasue of the time it takes for personnel and aparatus to arrive (and the more invasive nature of those firefighting techniques), or you can minimize that damage with nearly instant response from within the building. Water is damage, but fire is destruction. Sprinklers are absolutely useful, save property, and by extension save money. Where up-front cost/expenditure is not a consideration, they should be a no-brainer, and where cost is a consideration, they should not simply be dismissed out of hand as useless. Everything is a calculated risk assessment. TL;DR: I hear your valid desire to not have to include sprinklers, but the reasoning not to is flawed.
I think, as in my case, a bit of anger with the cost of them on top of lack of understanding and knowledge in their entire use causes people to not understand why we need them. Looking through the comments and also talking to different people through the fire sprinkler process we definitely learned a lot more than what was portrayed in this video.
I believe city code required us to use CPVC and pex is prohibited due to the level of pressure required to be in the fire sprinkler lines at all times. Every municipality is different.
I’ve been plumbing for over. 20 years and I’ve never heard of 5/8” copper pipe. Just 1/2” and 3/4”. And I’m puzzled by the potential problems and damage from insulated electrical wires touching the orange CPVC pipes. What special coating is this?
If you have a flame that is about 5-6 feet high in your home, you've got about 15 seconds to get out before the oxygen combusts in the whole home. Find out the next time your local fire department is doing a side by side fire demonstration of a room with and without fire sprinklers, then decide if it is useless or not.
for the Meter situation... was a pump and tank not an option? cheaper than a new tap from the city... unless your local fire marshal wont allow it... for aesthetics, there's flat plate concealers. Also as for "flooding". Most fires are controlled with 1 or 2 sprinklers. If a head goes off, depending on the pressure at your house it will be discharging between 20-40 gallons per minute. Typical fire department response times in a suburban area is around 10 minutes once the call is received, so lets say 15 total (if you have a water flow alarm on your system then your alarm monitoring company will make the call). At the most, 40gpm x 15 minutes = 600 gallons.... When they do get there, the fire will most likely be extinguished. The system will be shut down, head changed and now you have a mess to clean up in one room. Without sprinklers.... a fire in a room grows exponentially without anything stopping it so that a situation called "flashover" can occur in as little as 1 1/2 minutes. This is when the fire erupts out of that room and spreads rapidly throughout the structure. So in the 15 minute response time for the fire department the fire has now spread to 1/4 to 1/2 of the house (15 minutes is generous too because unless you're there to call, no one else will call untill someone sees smoke or flames from the outside). When they arrive, theres another 2-5 minutes of setting up the hoses, hooking up to hydrants, and getting into position for the attack... if they think the roof is involved, they get up there and tear holes in the roof for venting and then they start spraying water from the hoses, at 250 gallons a minute per hose, for however long it takes to put it out. in the end they could end up using 20-30 THOUSAND gallons of water... vs under 1000 for a sprinklered home. Plus your house is burned down vs. having to fix a room. Sure, if you're there and awake with a fire extinguisher handy you could catch a fire and put it out.... what about when you're asleep, or not home or in another part of the house and something starts? If they accidentally go off, as with everything with your house, know how it works... know where the control valve is and shut it, then open the drain. This will stop the head from discharging almost immediately. One big tip for everyone is have the installing contractor include a spare head cabinet AND wrench. This should have spare sprinklers of the ones installed on your system. Its required by code on commercial installations but not on single family homes... they'll charge you for it but its worth the $200 or so. Each sprinkler has a specific wrench that goes with it that you have to use (or else you'll damage the head) and if you have one break you can change it out quickly.
You would have to drain the entire system in order to do this. Sprinkler lines are usually pressurized. The last of moving the line is very similar to moving a lawn sprinkler line, aside from the high pressure aspect of it. I would not recommend doing this yourself if you have no experience with fire sprinkler lines.
Also that sprinkler head may already be max distance off the wall,or that one foot might also put it too close to another head or a heat source.check your codes.
How did you pressurize the lines? I just saw a video by a company that makes sprinklers that said never to pressurize cpvc with air or gas. I'm wondering what's going on in that regard. Thanks.
What our installer did was fill the lines with water from the main water supply line T'd off to a different pressure regulator. Before the fill he adjusted the water pressure regulator to match what pressure he needed in the lines. The lines are now always pressurized always and ready for a fire!
11 months later. Testing with air is more volatile than water. So it’s a safety factor you have unglued fitting blow off or compromised pipe exploding.
Always get multiple quotes, sometimes some guys are really busy and overbid a project. Sometimes a crew needs to fill in a dry period and you can get a good deal. Always shop quotes around!
These were in fact sprinklers that deploy only in the area the fire would potentially be in. We were just very ignorant on the topic when discussing it at the time.
@@SEFSU hey buddy, Ifire protection inc., please look into my company.. and let us know how we may help you in the future if infinity is to get too busy or something one day… Thanks.
Typically, only one sprinkler will go off in the event of a small fire. Not all sprinklers go off at once, like in the movies. That’s Hollywood. The only time this happens in reality is if there’s a massive uncontrollable fire from some explosion or Molotov cocktail. The other scenario is in an airplane hangar, a special type of system, where all sprinkler heads are controlled by one valve.
I'm putting a system in my house without any requirements because I'd rather wake up to cleaning up some water then never waking up because the smoke killed me and my wife in our sleep--damn California and all their hippy rules
I assume you are referring to blazemaster CPVC pipe, it will melt like any plastic. It is designed to handle heat a little different than other CPVC pipe, but will melt. The drywall is protecting the CPVC from the heat and the sprinkler head is controlling the fire so it doesn't reach high temps that would get past the drywall and to the pipe. CPVC can be exposed, but with restrictions including the temperature of the head.
Correct, cpvc forms a char that actually becomes a protective layer in a sense. The drywall is fire rated but is not there to “ protect “ the pipe. It can handle extremely high temps thus it’s UL listing. Also, sprinkler pipe needs to be hydrostatically tested at a minimum of 200 psi or 50 psi above maximum working pressure.
wow what happened to creative thinking, its very easy to put a drain in every room for the sprinkler, they can be hidden and they can have their own drain pipe connecting all of them to one drip s pipe. so only one room gets some fire damage and free from any water damage, even flooding.
@@johnwilliams-ni8cn Pressure comes from the city line and is regulated down using a pressure regulator valve at the home. I honestly would not know the answer for an apartment building.
I wouldn’t use the words very easy to install drains over a house. To maintain pitch with existing obstacles is quite challenging. Not only that you would have to waterproof everything for drains to work. Carpet areas as well would be a change for a floor drain.
To say the sprinkler is useless is the dumbest thing I have ever heard. I bet if a fire burns your house down with someone inside then you would never say something so stupid.
Wrong, Wrong, WRONG, the size of the supply line has nothing to do with the spread of the water; there is a combination of pressure and friction pressure losses. Step 1 - get the right engineer Step 2 - coordinate with mechanical, electrical plumbing, and architectural design. Step 3 - get the right installer FYI. 16'x16'=256 sq/ft, the design requires 26 GPM. To utilize 20'x20'=400 sq/ft, the design requires 40 GPM, only 13 gal more. So you guys paid 40% more for the sprinkler system.
That cpvc pipe is garbage! Gets brittle with age . Changing out sprinkler heads later , good luck you will be cracking and breaking pipe. If it freezes it will crack. everywhere. They should have never approved this pipe .
these guys are saying all the codes and requirements for sprinkler system. for the most part they are the same but they don’t realize that these codes change from state to state, even city to city
buddy you know nothing a sprinkler system and if there’s a fire in the house guess what you’ll be getting flood damage from fire department and their not shy with spraying water.
