While fully allowed, having piping containing water in a dry pipe system most likely will lead to accelerated corrosion of the dry pipe piping system. 

Thanks,

I have a dry system that is feeding upright sprinklers on sprigs in a heated light hazard space. The owner wants to add ACT. I’m wondering if I can use flex drops into the ACT. Feels weird, but I cannot find any reason why I shouldn’t.
