hoosier inspector Posted May 9, 2012 Report Share Posted May 9, 2012 I was just wondering if any of you guys that inspect suppression systems could enlighten me. Why all the fittings? This set up repeated itself over 150 times in the building. This was in a hallway aprox. 6' wide and about 7'6" off the floor.

inspector57 Posted May 9, 2012 Report Share Posted May 9, 2012 I'm not a sprinkler expert but I would just assume the fittings were needed to properly position the head out of harms way at the bottom of the feeder pipe as well as enableing the head to be aimed the right direction.

Brandon Whitmore Posted May 10, 2012 Report Share Posted May 10, 2012 I'm pretty sure Jim is spot on. Had they turned that first elbow they would have eliminated half the fittings, but the head would have been lower. Quote Link to comment Share on other sites More sharing options...

That's what I saw, it looked like a street ell could do the same thing if you lifted the feed an inch, but I don't know much about sprinkler systems. I didn't want to mention it, but it was a union retrofit. Quote Link to comment Share on other sites More sharing options...

Brandon Whitmore Posted May 11, 2012 Report Share Posted May 11, 2012 I'm a union pipefitter now........... well, I'm union, and I do a lot of pipe work. Street elbows are known to be problematic, and would have been a bad choice. Our company policy is to not use them at all, and from my experience of running around fixing leaks day in and day out, they shouldn't be used.
