Every house must have one 3 inch vent. Toilets must have a 2 inch vent
minimum. Just do what he wants and be done with it. If you are unable
to
figure out what he wants get a little help from a real plumber.




I've heard other people say that a toilet must have a 2" vent. Can you
quote the UPC chapter and verse that says that? I was looking for the
reference.


As stated, Codes vary, but one says in effect that there
shall be at least one vent terminal which is the same size
as the main stack. So the requirement for a 3" vent may
not be unreasonable.

Any house with over 20dfu will get a 3" main vent like you say. I have
always used 1 1/2" vents on WC with 3" main and 2" for 4" main. I just
thought maybe there was some clause somewhere that said that WC had to be
2" vent.
