I have had to do this on some 13R group homes. The AHJ wouldn't accept a single
2-1/2. Seems like overkill. Two 2-1/2" connections fed from a 1500 gpm pump for
a 55 gpm demand. We ran 4" to the riser room and connected with a 4 x 1-1/4
welded outlet.

Looking for opinions. AHJ wants to swap out a single 1-1/2” FDC on a 13R system
and replace it with a standard 2-way (2-1/2”) FDC. Thoughts, concerns,
suggestions, etc…..
