When testing do you have to close the valve to the main fire system..?

@@jj13jh NFPA 25 doesn’t require you to close it, but you can. If you decide to close it pay attention to where the sensing lines for both the fire pump and jockey are connected. It shouldn’t be an issue if installed correctly but I have had problems with this in the past.

good

Always better to find out something’s wrong at peak flow in a routine test than in a fire when the fire department shuts off power to the building. Great choice to go back to NFPA recommended test procedure!

When the pump on zero flow shut down the primary source of the power does not activate the secondary power source / generator? why did you need to get inside the settings of the transfer switch?

Good job on the explanation. When I'm testing fire pumps I will always inform the owners and if possible, their insurance company to get approval before performing peak alternative power test. After explaining the possibility of damage, though small, I have had some ask we do not perform that test. We still make sure the generator kicks on when simulating power loss just not always at peak. My experience over the years is that standards change. So before performing tests that could potentially cause damage be sure to cover all your bases and think through it before you do it. The potential damage will most always be blamed on the company performing the tests.

good overview, thanks

Yet another great video. I did pick up a few pointers. You mention the Bluetooth transducers . My company just got me a set of them. I've used the once so far, just haven't figured them out yet. I'm sure I'll get the hang of them this summer.

Nice, let me know what you think of them after you use them for a while.

This video has helped me out alot and im not just saying that. I run the diesel fire pump and electric fire pump every week/month at work and this has trained me on some conponents that i didnt know about. Just subscribed

that new technology will be great for you guys testing , save you running time back and forth and als you can work those outside valves correctly !

Well that amd in the case that they water mains do fail. At least you aren't finding out in an emergency.

we use a different type of grease on our pumps and electric motors. we use a die eletric grease on the motors

-30 vacuum reading isn’t just for tank supply. You can pull vacuum on city supply mains and collapse the underground. Having tested fire pumps for the better part of 20 years I can get pretty damn close to zero on the city supply and listen for cavitation to prevent any damage.

MAN A SET OF THE NEW SMALL HOSE MONSTERS WITH REMOTE STATION WOULD BE SWEET!!… Just a quick check to see if OUR bosses are watching!!…

Hmm, we don't run our generator when we churn test

You are not required to transfer to the generator during the churn test. You are required to during the annual flow test.

How do you test the a pump?

I’m not sure what you mean? That’s what I’m doing. I’m flow testing the pump to make sure it can pump the required amount of water.

Hi Sir, May i know the specs of grease gun that u used? and the types of grease? Thanks a lot

I use Mobil Polyrex EM on the pump and electric motor. www.mobil.com/en/lubricants/for-businesses/industrial/lubricants/products/products/mobil-polyrex-em

How many HP is that pump?

@@FireSprinklerTech I work in maintenance at a 350000 sq ft distribution center. I handle the monthly testing on ours but we contract out the yearly testing. Nice video.

Nice setup, too bad they used the worst motor...WEG motors are junk. Not what I'd want on a critical system. Edited to add: Your peak transfer test is totally invalid. By throttling the flow back, you lowered the current draw on the pump and completely voided the intent of the test. This is a serious issue, and hope you did change your proceedure after as you said you would. And IF a water hammer happened and caused damage, better to find out under test than during a fire.

U need a helper
