Earlier this year, I received an announcement to go to the ICC website and read the Plumbing Code Economic Impact Report. I would encourage all of you to do the same. The website is: www.iccsafe.org.
Without looking, I knew the report would be a cost comparison between the ICC International Plumbing Code (IPC) and the IAPMO Uniform Plumbing Code (UPC). As expected, the report showed how much of a cost savings there is for the installation of plumbing systems when you follow the IPC, compared with the higher cost for the UPC.
