Case in point, I just had a job where there was a mega flange caped with a blind flange, when the general used our fire pump to fill the underground, he blew the flange off. It bent out 6" main directly above. The riser was not built because we did not have the UG test certificate. The mega flange is now bolted to the floor.

In those cases the retaining rods would still be required. - MAS -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of George Church Sent: Tuesday, October 20, 2009 4:00 PM To: [email protected] Subject: RE: Retaining rod on UG-tangent Set screws? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mark Sornsin Sent: Tuesday, October 20, 2009 4:50 PM To: '[email protected]' Subject: RE: Retaining rod on UG-tangent Geo.: Are you saying these rods may not be necessary because of the restraint that may be present at the 90 deg. elbow below ground? If so, what would be restraining the flange they're tying into (above the floor)? Mark A. Sornsin, PE Fire Protection Engineer Ulteig Engineers, Inc.

Has the floor already been poured @ the run-in?
