There is a new round of plumbing code politics that has permeated the plumbing industry. As with any political arena, there are a lot of half-truths and innuendo being passed around. Furthermore, all sides are to blame.
Since I am involved with all of the plumbing codes and have the fun (and I mean fun) of attending the hearings, let me try to set the record straight. There are two major model plumbing codes in the United States and one minor code.
