With that I learned they meant absolutely nothing. It is what it is. As for mechanical fittings and flow switches, the first is easily seen not made up and the second easily tested via the ITC. Roustabouts and Morton salt also come to mind. Good inspectors who know what they're looking for make sure things are right in the end, coupons or not. Some story from AvalonBay.

Also any fitting that knows what he's doing has a strung together mass of coupons for every pipe size. For the "just in case" you lose the coupon, albeit not from leaving inside the piping but rather losing it after you remove it. Or rather I hope it's not from losing it inside the pipe. Correct me if I'm wrong but I believe there is a requirement for proving that the hole is actually cut and the switch or tee is not just stuck on the pipe. I seem to remember that. And the code didn't say how you prove it but that having the coupon attached to the device or fitting "proved" that. -- Aaron Peck, SET • Fire Protection Engineering Technologist NICET Certified NFPA Member Skype: (202) 407-9079 • Cambodia: (+855) 78700407 **Currently in Manama, Bahrain UTC/GMT +3:00 hours (8 Hours ahead of EST)** **Bahrain Number #(+973)39605669 Skype forwards to this #** -----Original Message----- From: Sprinklerforum [mailto:[email protected]<mailto:[email protected]>] On Behalf Of JD Gamble Sent: Thursday, February 19, 2015 8:46 AM To: [email protected]<mailto:[email protected]> Subject: RE: Mech Tee Installation Thanks for all the insight.
