I am working on a project in a wood frame building where they have ceilings at varying heights. In the high ceiling areas (about 50% of the space), there is 5” between the ceiling and the bottom of the joists. These do not require sprinklers per 9.1.2.5. In the low ceiling areas, th

One of the problem is that insulation installers are not consistent. Some may stop at the joists, others may just let it flow. It is almost impossible to properly install sprinks until after the insulation is in, but then it is difficult to hang the pipe. On one job I was w

A lot of good responses. Another consideration might be if you would be required to do a drain test from this connection. That would be under pressure and a higher volume that a straight drain. It might need to be considered in the roof drain design. > > On Aug 2

Tim, Craig pretty much nailed it. This is not a sprinkler issue. The HVAC crowd needs to solve this. My concern is why is this a wet system to begin with? Somewhere there is a chiller that is pumping out air a lot colder then 40 degrees to maintain that temperature; probably at roof
