I have a long vent for a vanity, 30' where 23' is horizontal to a 2" vent stack.
UPC says 120' max and 1/3 of which (40') can be horizontal.
My question is: does this mean total horizontal vent length in the entire house
Or , is 40' allowed for the new branch vent with 3 dfu's ?
I can use 2" vent if that helps. Oh, the damn thing will have to bend a total of 270 degrees as well.
Thanks.
