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. via Newton Mail<https://cloudmagic.com/k/d/mailapp?ct=pi&cv=9.1.21&pv=10.0.2&source=email_footer_2> On Wed, Oct 12, 2016 at 9:13 AM, Brian Harris <[email protected]<mailto:[email protected]>> wrote: Double (Siamese) Brian Harris, CET BVS Systems Inc. bvssytemsinc.com<http://bvssystemsinc.com/> From: Sprinklerforum [mailto:[email protected]] On Behalf Of Todd Williams Sent: Wednesday, October 12, 2016 9:11 AM To: [email protected]<mailto:[email protected]> Subject: Re: FDC on 13R [https://tr.cloudmagic.com/h/v6/emailtag/tag/1476277888/01c6e4fe7e8b46e8dfef813adf427213/ecdd64c309bb34b23eb65c654267bfff/baa43dc780325ba131c97b912a7e0d62/9efab2399c7c560b34de477b9aa0a465/ufo.gif] Single or double? via Newton Mail<https://cloudmagic.com/k/d/mailapp?ct=pi&cv=9.1.21&pv=10.0.2&source=email_footer_2> On Wed, Oct 12, 2016 at 8:07 AM, Brian Harris <[email protected]<mailto:[email protected]>> wrote: Looking for opinions.
