    Venting an added basement bathroom
    I'm having trouble finding a spot to tie in the vent system for the bathroom that I've added in my basement. The vents for the rest of the DWV systems in the house are upstairs and not accessible. I have a "burp" vent in the top of the vent pipe down in the basement but the inspector said I need to vent to the outside. Does anyone know if it is permisible to tie to the sump pump vent?

    Sorry Mkromer...

    It is not permissible to tie into the sump pump vent... nice try though... ;)

    From your description, you can open the wall up at the floor above and connect into 2" vent from the existing bathroom... OR perhaps you can find a closet upstairs that will allow you to run a pipe up through the closet (tight to left or right side of the closet) and into the attic where you can connect into a 2" vent up there (or connect into the 3" pipe just before it exits the roof).

    The closet works great in that you can install the vent pipe over to one side (no box required) or you can even pipe vent toward the back of the closet and then build a box around that!

    Otherwise... you may be able to send a vent out the side of the building as per the following code requirement:

    In my code book (Massachusetts, Uniform State Plumbing Code, 93), "No vent terminal shall be located directly BENEATH any door, window, or other ventilating opening of the building or of an adjacent building NOR shall any such vent terminal be within TEN FEET horizontally of such an opening unless it is at least TWO FEET above the top of such opening".

    So, if you can install the vent outside and not be within 10 feet horizontally or 2 feet vertically of a window or an air conditioner or skylight, etc... then may be that you can penetrate the wall of the house with vent and call this done without tearing apart too much of the house. Of course, you would need to check with your plumbing inspector to see if this is allowed in your area. If it is, the inspector can tell you how he wants the end to terminate (Up or down, etc.).

    Let me know if you have any more questions...
