I'm a firefighter and your detailed explanation has helped me understand this vital portion of my job. Thank you for your time, your expertise, and for taking the initiative of making it available.
I learned more about fire pumps watching this video than I ever did from reading about them in the fire academy. Great explanation. We actually had a call today where a loss of pressure had caused a big pump like this one to come on at the local state college. Felt good knowing how to get the system property shut down and reset.
Scott Gordon deserves a raise. I've been around plenty of so called Sprinkler technicians that "know" what they are doing. I can only think of one that could hold a conversation with this guy. Great explanation!!
Definitely explains a lot I haven't put in a fire pump in 12 years and I don't know where I got in my head that the bypass valves had to stay closed the only thing that stays closed is the fire pump test header I felt like such an idiot when I was doing my tampers and flows today,, I'll know better next time. A very good refresher course video.
Keep on sharing bro. God Bless. Very informative instruction for fire pump. Hope I should learn more procedure specially pump controller how to operate for running the pump.
I do fire pump testing about every other day in NYC high risers, pal. We do a churn with closed discharge and then we do another churn to get pressure at top of the head to help reset relief valve.
You need fore for closing that valve. Your never supposed to close that valve even when your working in the fire pump cause the discharge check should hold. You should be fired. Uour Lucky you don’t work for me because whoever you work for us just as incompetent as you. Your def not a union guy.
Just to be accurate the pressure relief valve he refers to is actually called a casing relief valve it is operated by water pressure and is used to keep the fire pump cool when it is running at churn. It simply drains a small amount of water from the discharge side of the pump which brings a small amount of cool water from the supply side which keeps the pump cool, while the casing relief valve is operating feel the water it should be a little warm. Overall Good Presentation All the Best
Young fitters should take note - this man's hands are clean because of what he knows. Put your time in and learn this trade and it will take care of you.
Great Video, this has helped give me a better understanding a pump system, very thorough and detailed, and an excellent pace that makes this easy to follow
I, personally, would not route a water pipe into an electrical cabinet. Instead, I would put the pressure sensor outside the cabinet and route it's cable into the cabinet. That looks safer to me in the case when a pipe or a sensor starts leaking.
Excellent advice. It always scares me to start a pump and let it churn, seems if there's a weak spot, I seem to find it. So you would note on the paperwork that the valve was closed during the test, then reopened and verified at the control panel for proper signal restorals. Have you ever experienced any leaks or problems while running a pump? Also, does the air bleed valve on top of the pump "spit" or "hiss" when running? I find them clogged and rusted all the time. Thanks again for a super job
Color coding of sprinkler heads is specifically for us(Sprinklerfitters) to identify the degree of the head 155 is red, 200 is green, 286 is blue, etc. There's also fusible link heads as well. It's supposingly a trade secret of what exactly is inside the head itself. The bubble inside is different size pending the degree of the head and also if it's standard response or quick response heads. Hope that helps.
I know not all buildings have this type of machine, or maybe that I have seen. I would imagine there are different setups for different buildings...so what size building is this system in?
Thanks for the video. When there's a fire though, will the jockey pump be also running? Since Jockey pump turns on first before the fire water pump reaches its switch on pressure I'm thinking it's running but I am not sure though.
Both the fire pump and the jockey start and stop on pressure settings. If the fire pump is able to maintain a pressure above the jockey pump start the jockey pump will shut off. Thanks for your interest!
Not a bad video. Def a couple things that were wrong. But all in all not bad. No return bend on the air relief on the lid of the pump head. That’s an nfpa 20 code. Copper drain lines in the packing drip cups are just stupid an a headache waiting to happen cause there going to get clogged. He barely touched on the CRV or circulation relief valve on the fire pump. Other than those couple things it wasn’t a bad video. For being non union his knowledge is semi extensive.
Question: 1. What will happen to your jockey once the electric fire pump kicks in its design cut in pressure? Does it operate together with the electric fire pump or will it stop?
I live in NYC and I'm the super of a small building. I want to get my S-12 and S-13 certificates of Fitness from the FDNY. Do you guys make good money? Can one run a bldg as a ceif engineer with al those certificates?
Question: Where is the water going when the pump is running during 10 minutes? I understand that the test header valve is closed, so the water is not escaping there? Is no water flowing?
When an electric pump starts in churn the casing relief valve is supposed open and flow a full pipe of water to a drain. Once you start to flow water anywhere like for instance doing the performance test the crv should close. And for a diesel when it fire up in churn your should be getting a full pipe of water from the heat exchanger piping to keep the engine and the pump cool. It acts the same as a crv on an electric driven pump.
Does the fire pump always work at max capacity? For example if my pump was 1000 GPM / 10 bars, but only a landing valve was opened which requires ~250 GPM / 4.5 bars. Would the pump work at 1000 GPM / 10 bars and the excess water be thrown out with the Pressure Relief Valve?
If the jockey pumps are properly set per the "intent" of NFPA 20, A.14.2.5.1(4), there should not be a problem as this is what the system would be looking at if there were a fire. Keeping the pressure switch settings narrow, reduces the water flowing on start up. If the jockey start PSI is set at the fire pump churn and Stop 10 - 15 PSI above that, there will be no water flowing when you start the fire pump as along as the supply remains the same, the system will be at churn, not 10 -15 less
What in the world are you talking about. Regardless of what the pressure is set at the circulation relief valve needs to open to let the hot water out and allow cooler water in. The two word enemies of an impeller is heat and cavitation. So what you said don’t make one big of sense. I’m an instructor at the union hall and our coordinator is the UA fire pump instructor. Ifso facto he knows a shit ton more than anyone you know. That’s a fact. He’s gone to trainings for every major pump manufacturer and they all said the same exact thing.
This video was produced back in 2011, so we're unsure of the exact size of the pump. Fire pumps are built and sized job specific. Thanks for commenting and subscribing to our channel!
This particular installation is just a single fire pump. Multiple fire pump systems will be used in applications such as hi-rise buildings where high pressure is required or in special hazard applications such as aircraft hangar foam systems where a back up pump is needed. Thank you for your interest and for subscribing to our channel!
Hi I've seen you use emergency backup power. I was wondering whether you use a diesel generator or maybe it is bettery pack. Also I've seen in other videos diesel fire pumps, not electric driven pumps. Do you know which system is cheaper? I'd say that an electric pump with an emergency diesel generator would be a little more expensive, but let me know what you know. Thanks!
You could never afford the huge # if batteries to provide emergency power for several hours on a 199 HP motor. While at a continuing education class some guy asked the instructor if you could use Solar cells to supply smokers envy power to a fire pump. I struggle told him only if you had guard 24/7 sunshine. In my big city in small to medium buildings that have dual electrical services you do not need an emergency power source .Hospitals & high rise buildings require emergency generator.
If you manually start a fire pump the run timer doesn’t engage. If the run timer is set to any specific time it only engages on an automatic start. For instance when we do 5 year flow testing on prv hose valves we set the time at 1 min to flow the valves with the pump on and when we stop the flow the pump only runs for 1 min and shuts itself off so we don’t have to have someone babysitting the fire pump at all times.
Ahmad Al-Tawabini no the municipal Supply is much less; here it is more like 60 PSI. The fire department Connection is on the discharge side of the pump; therefore the suction line would not reach any where near 300 PSI.
before i even get a minute into the video, can I comment on the camera skills? They leave MUCH to be desired. in the beginning of the video, when the super stepped off to the left, would have been nice to see what he's pointing at. what he's touching. because I am as green as grass. Just sayin'. other than that, thanks for your time man in making the video.
The large hospital/research center/Ambutory care buildings that I retired from had 7 fire Pumps from 75 to 250 HP. I was INE if the electricians who had to run them every week & perform Quarterly PM'S on. Hate how lazy sprinkler guys install angry water pressure gauge sideways. Only takes a minute to install a Nicole & a 90 degree elbow to have them facing straight up making them easier to take readings. How the hell do they get a way with using open motors on all fire pumps instead of the TEFC ( totally enclosed fan cooled ) motors. Have seen every fire pump several times have bad packing then spraying water over open motors and water getting into motors. Hospital fire pumps do not time out after the usual 10 minutes of test run like other buildings. We had a for pump panel like the in your vidio. Had the cheapest piece of shit contactors which you could not remove cover to inspect contacts . We always had to open the drain valve below fire pump water pressure gauge to start pump then record that reading.
This is by far the most informative and instructive tutorial I have seen in fire protection, keep up the great work....

This guy knows his stuff!
does the JCO or CMS inspectors in verify that these weekly fire pump checks are happening or being conducted? If so, how does this get documented?

Thank you for your comment!
On a tamper switch you will get a Supervisory alarm not a trouble. It is important to know the difference between them both.
Correct.
Supervisory signal. Neither trouble or Supervisory is an alarm
Sprinklermatic is a great company
Il serait très intéressant de faire cette vidéo en français pour nous permettre de comprendre le fond de votre démonstration.
Thank you for the video! Very informative!
Good comment. Fire sprinklers should be mandatory in all structures.
It's loud but still not as loud as our diesel powered fire pumps at the plant I work at.
I have one in a small room and I was standing right next to it and it turned on, still can't hear
good day how do one get full training on fire system with sprinklers online training if possible with certificate at the end

When the fire pump starts to run automatcally theJocky pump will not run.
Both pump will not run together automatically...

Question: Where is the water going when the pump is running during 10 minutes? I understand that the test header valve is closed, so the water is not escaping there? Is no water flowing?
There is a Circulation Relief Valve which will make a flow to avoid heating of casing of a Pump.
Hi the water goes through the casing relief valve also this is used in the diesel engine system
When an electric pump starts in churn the casing relief valve is supposed open and flow a full pipe of water to a drain. Once you start to flow water anywhere like for instance doing the performance test the crv should close. And for a diesel when it fire up in churn your should be getting a full pipe of water from the heat exchanger piping to keep the engine and the pump cool. It acts the same as a crv on an electric driven pump.
I set those up with Detroit diesels for backup grid pressure Major government facility.
Thanks for the suggestions you have discussed here.

The circulation relief valve only flows enough to keep the pump cool, like 50-100 gpm.
Well done. great video!
Major flooding is right...as those look like some major pipes...and those pipes look like they major bolts connecting them together.
If the jockey pumps are properly set per the "intent" of NFPA 20, A.14.2.5.1(4), there should not be a problem as this is what the system would be looking at if there were a fire.

would the city water reach 300 psi on the pump suction line
Ahmad Al-Tawabini no the municipal
Supply is much less; here it is more like 60 PSI. The fire department Connection is on the discharge side of the pump; therefore the suction line would not reach any where near 300 PSI.
Thanks Robin, 60 PSI is reasonable. I wondered When I heard 300 psi
@@aftawabini that might be the out side.
