I am an AHJ and trying to determine if this CPVC/BlazeMaster pipe has the correct hanger arrangement.
I was unable to find anything in the BlazeMaster installation manual. You can see from the photo that the sprinkler branch line hanger is attached to the building steel structural beam.
However the sprinkler drop is supported by a hanger, attached to the branch line, and not to a building structural element.
Is this a correct method of supporting a sprinkler drop?
