We're working on adopting the 2009 Codes in our jurisdiction. I note the Tee Application prohibition of the 2006 IMC 1206.1.1, "Fluid in the supply side of a hydronic system shall not enter a tee fitting through the branch opening.", is deleted in the 2009 IMC. I can't find mention of the reasoning behind this revision in the 2009 Significant Changes to the IPC, IMC, IFGC. Can anyone point me to where I can find the basis for the revision?
