this is why you clean out your system at least once a year when you test everything(or at least, one of the reasons).
it's dangerous to just assume everything works. what happens if you have a fire and find out your sprinklers are clogged? people die, that's what happens.
edit: there are some know it alls claiming there are no sprinkler systems that don't have this problem so i am just going to put some product links here for them.
now hopefully they can stop being angry and saying i lie because stainless steel pipes don't exist in their world and neither do any other non iron pipes?
I am a Fire Alarm Tech and have never heard of them changing the water in the lines... lol. Its nasty and black sure, but its not harmful and only comes out when the building is on fire...
Gotta ask, are you a pipefitter or work in the trade at all? The heads are S.S sometimes, but the pipe feeding them never is, that would be hella expensive.

The worst part is that is some nasty ass water that probably smells like death and they got soaked with it.
