OK so the rubber fitting is a simple enough fix. Can you please describe the danger of the flat vent keeping in mind it is a dedicated vent for a kitchen sink. Also, unfortunately the joists are 12 feet. About 3-3.5 feet to one side of the holes.

I'll keep it simple, Dry flat vents over time will get clogged.... Now you have no vent and no way to clean it out. Also your vent needs to rise vertically above the trap of your sink trap. Your not venting anything when its below your trap.

can you contrast that with how you would clean out a clog in the horizontal portion with a properly vented system?

When a sink gets blocked one removes the trap and snakes the drain. When a dry flat vent gets blocked do you plan on cutting open a wall cutting open a pipe to snake it?

It just occurred to me that there might be a misunderstanding about the vent. It runs horizonal from the fernco about 3 feet to the left then goes vertical about 25 feet through my roof. Does that change anything?

The question is how are you venting the new sink? This one does not do it.

I have no idea. I max filled the sink and drained it all out at once. I could feel the air being pulled in on the roof vent stack. I'm not sure what alternatives I have. I have no wall access at this point and no way to tie it to a straight vertical line without some kind of horizontal run.

Just leave the old vent alone isn't hurting nothing. Do it as soon as you have the time.
