    Moving a bathtub drain and vent
    I want to move my bath tub and the wall that the vent and drain are in about 3 feet so is it OK for me to "T" back into the original vent in the attic? Or does the vent need to go straight up through the roof and I need to drill anothr hole in the roof

    The vent line does not have to be all vertical. Just pipe it back over to the existing line out the roof.
