Sprinkler riser size 1

[JoeWill123]

Why would an A&E desighn a sprinkler riser in such a way that the existing water main to tape into is 6 inch, but the A&E is desighning an 8 inch on top of the 6 inch pipe as it enters the facility ?

Is it normal to go from a 6 inch supply line to a 8 inch riser?

If so why?

If this is a military project and you are using UFC-3-600-01 as a guideline, the use of QR sprinklers will allow the design area to be reduced based on the ceiling height. This will help to get you some pressure back.

I just completed a military storage building this past week, so I am all too familiar with their requirements right now :-(
