Otherwise you will have to cut in a tee downstream, from the trap and roll it up on a 45 degree angle, come off that tee with a street 45 and run to the attic where you can either run it out the roof or connect back to a existing roof vent using a inverted tee, Or, if code permits, you could vent with a AAV. Good luck, YTom
