Good work! All engine companies should be familiar with these techniques. Unfortunately, many engines in urban areas no longer carry hard suction hose. The only suggestion I would add is adding a suction strainer to the suction hose when drafting from a water source like the one shown to prevent debris from being sucked into the pump (not needed if drafting from a clean source like a swimming pool).
If you have a large amount of height to overcome, (head) you can open the intake valve before you increase the rpms and before you close the tank to pump and let water back flow into the hard suction. This will lessen the amout of air you have to remove with the primer pump.
Depends on the operation. Our technique is always pump on before you leave the cab as well, but if it’s gonna take me a couple of minutes to get it set up I will not put the pump in gear until I’m actually ready to drive. No point in getting it hot needlessly, although you can always open the tank to pump and the tank fill valve in the meantime to keep water circulating and keep things cool.
I guess Im randomly asking but does any of you know a way to get back into an Instagram account?? I somehow lost the account password. I appreciate any tips you can offer me
@Brayden Thomas I really appreciate your reply. I found the site on google and Im in the hacking process now. Takes a while so I will reply here later when my account password hopefully is recovered.
where did the chocks go? I was about to give you props for using them. a neighboring fire dept. never uses them normally they can get away with it, but one day they parked on a hill our tanker was parked in front of it. Their engine started to move slamming into the back of our tanker. If it wasn't for us using chocks both the tanker and engine would have been sunk in a near by creek. their is a reason why we carry them use them!!
Angel Reaper . I did the whole video without them, I totally forgot to be honest but at the time to edit the video I noticed, so we went back and shoot that portion and added it
strainer is on ....good job....I once watched a crew ''try" to do a drafting operation at a fully involved apt fire...after about 15 minutes and a smokin hot primer motor...and about 8 firefighters trying to trouble shoot....yep ...you guessed right ! pump was not engaged.
I know this is a crazy old comment. I saw a guy on my department pull a draft without having the pump in either pressure or preferred RPM model on a pump. The pump was engaged by running at idle. The guy was a pump tester at Pierce prior to working on my department. I was literally in awe as I watched that. He also did not use the primer at all. He simply back filled the line through the Keystone valve and pulled a draft from a portable tank.
What would you do in the instance of drop priming? Just open the intake and the tank fill let water fill the hard suction and then close the intake and then basically begin drafting by increasing RPM's? I have an engineer's test this friday and am trying to prepare.
Many Firefighters don't understand what it means when you have a 1500 or 1250 GPM pump. The rating is from a draft not tank to pump. Im sure this guy knows that. :)
The same purpose but a totally different tecnique as we have in germany. Of course every country has is own tecniques, but one thing I cant understand is why you use thread clutch instead of e.g. Storz cluth.
Josh Jourdan As long as you maintain your seals from time to time (tbh from year to year) you won‘t have any practical disadvantage from using storz couplings. At our department in Germany we draft on a regular basis and never had any problems with the couplings sucking in air. I also think american pumps could use some kind of automatic air draining device (I’m lacking a better term). Engineers over here don‘t have to drain their sucking pipe from air manually since the 1960s, but I believe this Varies from engine to engine.
With no strainer on the intake line....drafting from a pond.... 1000-2000 gpm.... how long does the impeller last with all the dirt and sediment and the occasional crappie being introduced into the pump system?
Ian Moniz it's the tank fill valve, once you open your tank to pump the water will revolve and heat up your pump, so by opening the tank fill valve you will send that revolving water back to your tank
dwc215 that is a good idea not to engage until you have everything set up, the only downside about that is that you have to go back into the cab and you might put mud on your floor boards,,,, haha JK, good observation!
His method here is far more common and makes more sense unless your engineer is extremely slow. To be idling your pump and opening up your tank to pump and your tank fill you'll be recirculating the water and at the same time getting your pump up to a good operating temp. It also saves going back in the cab.
Last year they had a capacity test over here in The Netherlands from a large static water canal, pumping 24,000 litres (about 6340 gallons) per minute! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ksOFJ3AdDoM.html
@@picoro228 high volume fire pump, used alot in the uk and western Europe in area's where water availability is an issue, comes on two prime movers, within 15 minutes of arriving on scene can be pumping 7000 litres a minute down 3 km of 150 km hose from any open source of water though it can use a hydrant
Fireman trying to sound way more sophisticated than they are, "drafting from a static source". Well you are actually pumping water, there is no definition of drafting in that respect, secondly the source is not static, clearly the water is flowing. Title should be, "operating (insert truck model) PTO water pump".
Wyatt Fisher What it is instead? I hardly believe that this fire engine has a second engine to operate the pump so I strongly believe that it is driven by a PTO.
The water source is static. A pond, lake etc is static unlike a fire hydrant which is under pressure and flows once it is open. A pond is useless unless you pull from it, draft. Most hydrants I have used have adequate pressure so as the actual pump pressure is not even needed.
