    Ignoring scale and any local requirements, yes, that’s a valid trap and vent.

    Be aware that local inspectors can be touchy about t-junctions. You might need a rounded or angled junction here so the new drain doesn’t splash directly against the opposite side of the vent.

        Without that extra loop, it’s possible that flushing the toilet will suck the water out of your sink trap.
