difference in plumbing codes
Posted by Hank on March 31, 2004 at 18:34:05:
I know there are basically 3 major codes in plumbing along with many, many local variants.

Can anyone explain the basic or fundamental differences in the UPC, IPC, and NPC?

I'm not talking about specific code examples like drain length or water supply, but general ideas about how the code was established.
