Correct, sprinkteach; nearly all of the work we do with the sprinkler outfits are on dry standpipes. (The only exception is when we roll in in the event of fire pumps being replaced or having failed, wherein either a stand-by or active flow is required based on the site's requirements.)
Some sprinkler people are confusing the Hydrostatic test, with a standpipe flow test, as done here. a hyrdostatic test (pressure test) is where you can use a small test pump to provide the added pressure. This test is to verify the waterflow and pressure at the most remote outlet as required by NFPA standards, when connected to a water source(pumper truck.) My guess is that this is a dry or manual standpipe system.
I guess it's all relative; the hydrostatic pumps can generate the PSI needed, but not always the flow. This test called for both 120 PSI and a flow rate of at least 500 GPM at the roof; most of those little pumps can't do that much... nor can they validate an engineer's theory that when connected to a fire truck, the system will function as intended. (And heck, if the customer wants a fire truck, it's their dime...)
We work as the pumper provider with the testing folks (sprinkler/pipefitter types) who coordinate the notices or shutdowns of water flow alarms, yes... last thing we need is more trucks on these narrow streets. :)
lol yeah... I hate when people forget to put their account in test mode... just one more false alarm to roll the trucks. Im not a technician- well, not officially. I am planning on going there in the future, after I finish college.
I install fire sprinklers and I have never seen a system hydro tested this way. The way my company does it is with a little 110 volt hydro pump. On some of the bigger systems this can take up to 2 hours to pump it up to the required psi.
We don't do a lot of these, but this one was apparently to meet the unique requirement of the location's management. (But typically folks either use a built-in or electric around here as well.)
@georei This was a standpipe acceptance test for the state fire inspector. I am the contractor that hired this truck. We were required to flow 1250gpm @ 100psi. I didn't know these videos were even taken but now you know why the truck was needed. We have hired FIre Trucks for Hire many times and they do a fantastic job providing all the hoses and adapters needed.

excellent work!

uh a hydrostatic pump is like the size of a microwave.
isnt this a little bit excessive?

Cool. did you have to disable the FACP before doing this, since it might have tripped a waterflow?

Thanks! It's ranks among the older ones in the collection, yet outshines the others when it comes to working like it did 30 years ago as a pup. :)

haha, I can't believe I found this. This is at the new underhill parking lot structure and I can see it right outside of my window, lol.

never seen a sprinkler system hydroed that way before!!

Eh, probably, but how much cooler is it to shoot water out of the big red toy? ;)
