Been using this forum for a while and it has been very helpful!
I'm remodeling our two bathrooms and had the plumbing inspection today (all good). One thing he did mention though was that the two bathroom fan exhaust vents were too small (4" flexible). He said Oregon code was 5" rigid (preferred) or flexible and all less than 25' in length. I found a site for Oregon codes (http://www.cbs.state.or.us/bcd/progr...ine_codes.html), but I can't seen to find reference to 5" diameter pipe. It's not that I don't believe him, but I'd like to know how to look these things up in the future.
Thanks for any hints or info...
