Curious how to install the inspector's test connection on this preaction system.
Any insight would be welcomed. I have a single interlock preaction system in a file room. All the pipe is in a conditioned space. Seems from what I can tell I need to use a dry inspector's test configuration with a drum drip. I was hoping to keep the valve above the ceiling and eliminate the drum drip. I was hoping to pipe down inside the exterior wall to the outside for my discharge. Is this acceptable? Or do I need to show a drum drip, then go out the wall. This would create exposed pipe in the room on the inside of the exterior wall. Regards Troy
