kitchen vent stack, construction concern
my kitchen sink needs a vent. It will -eventually- be a large farmer sink type also with a dishwasher. Nothing else will be draining on this line when I'm done the reno.
above my kitchen is an attic and then the roof as it is just one story. If I bring the vent up on the inside of the wall as shown, then I could just bust through the 2x4 wooden top plate and entre the attic. Then come back towards the kitchen a bit and then straight up to the roof (don't want the vent right near the edge of the roof after all!).
but I am concerned that I will weaken the integrity of the wall/roof joint because the vent will cut entirely separate the 2x4 top plate on the wall (see circled area).
use of an air admittance valve is not going to work in my situation because of code requirements.
thoughts?
