I have is a project where we need to run 1,700 feet of 10" to a booster pump so while the line will never see more than city water pressure it must be installed per NFPA #24.
I've always used C900 DR18 because it was UL Listed. FM Approved and it is what everyone always used.
Looking at everything I can find C900 DR25 is UL Listed for fire protection but, as we all know, it is not FM Approved.
Am I correct in thinking C900 DR25 meets the requirements of NFPA #24?
