From 2016 NFPA 13;::






My non engineer opinion you do not have a smooth ceiling

As far as the FDC goes, do you guys see it as an obstruction regardless of how the branch line is ran? Considering the spray pattern it shouldn't be an obstruction, correct? Can somebody go in depth about the 4-inch rule when it comes to sprinkler heads and obstructions? I would like to know other people's views that are more experienced.

Knowledge is power, thank you everyone for your input so far.

This book explains a lot of the standard in plain English/ non standard talk::

Even if you find a 2013 edition not much change in the basic stuff

I think it is

Sprinkler has to be four inches away from a wall, ceiling, or similar

Will check, might only be so you can get a wrench on it.


The book says "dead air space" and "detrimental effect"

In the 2016 edition, if you are asking about 8.7.5.1.4.1

I take that to be an obstruction in front of the sprinkler, like a solid beam hanging from the ceiling.

But, 8.7.5.2.1.1 says apply the eighteen inch rule. Which is like the storage rule below sprinklers.
Does say an exception is three inch pipe or less,,,,, which your set up does not meet.

I think the install has multiple problems!!!!
