    Default Basement bath vent check

    Greetings again from NC. My project is finally underway. Major delay was saving cash, and then getting the HVAC guys to move units and ducts.

    Yesterday I broke the concrete and dug the big hole for the sewage ejector pit. Today is (was?) going to be the DWV. I thought I had a good plan, but then woke up at 3AM sweating over the shower vent. If it is vented, that's the question.

    I'll attach a drawing, which may be clear enough. The shower trap arm is to connect to the 3" drain very near the wet wall, and where the sink drain comes down from above. I thought that the sink vent would be adequate to provide venting for the shower, but now I don't. I'm pretty sure that I'll have to put another fitting near the shower trap and run another line straight up to the wet wall to vent the shower. Is this right, or would my original plan, as drawn, work? I'm obviously trying to minimize concrete cutting, and I only want to do it once!

    Thanks, as always.
