A kitchen sink will be moved during the course of a remodel and I'm curious about a few things regarding re-establishing a proper vent. There will be a window only six inches above the rim of the sink. But it's my understanding that a vent line must rise at least six inches above the flood rim of an appliance before it can move laterally through a wall. So I'm not sure exactly how to get out from under that window... Somehow I have a memory that a vent can indeed run at a 45 degree angle (or even proceed horizontally with the proper slope as long as its travel is initiated with nothing greater than a 45 degree fitting) even if the vent line has not yet risen above the flood rim. Is this true? Obviously, I'm looking for a way to get that vent out from under the window assembly to a point where it can proceed vertically. I believe it will have to travel about five feet laterally until it is out from under the window. If that travel is initiated with a 45 degree rise, then levels off to a sloped horizontal run, then takes another 45 until it is over the flood rim... then finally takes another 45 degree bend to be truly vertical... does that make it okay? Thanks in advance.
