[RMERMP]

Can a fixed support for fire pro be use as support for other piping? thanks.

No

Yes, in the 13 edition. There are severe sizing requirements.
5 times the weight plus 250 pounds for sprinkler piping. 1.5 times the weight of the other systems using the "Shared Support", all certified by a registered P.E.
Reference 9.1 in the 13 edition of 13.

Is 9.1 saying it the other way around?

Or does it just seem that way? semantics

9.1.1.3.1.1 Sprinkler pipe and other distribution systems shall be permitted to be supported from a shared support structure designed to support five times the weight of water-filled sprinkler pipe and other supported distribution systems plus 250 lb (115 kg), based on the allowable ultimate stress.

9.1.1.3.1.2 Sprinkler pipe and other distribution systems shall be permitted to be supported from a shared support structure designed to support five times the weight of the water-filled sprinkler pipe plus 250 lb (115 kg), and one and one-half times the weight of all other supported distribution systems.

I have a PE sealed set of these right now I am dealing with.
It confused me as well.
It seems you either do #1 or #2. #1 being worse.

We went with #2 from the Structural Engineer.
