Thread: Venting toilet

  1. #1

    Default Venting toilet

    I have moved my upstairs bathroom across to hall. When it was time to put the 3" vent pipe through the roof I ran into trouble. I could cut through the double sill at the corner of the wall were the roof meets or cut through the rafter. I dont like my options. Can I run the vent pipe off the side of the house?

    Here you can't without permission from the inspector.

    if you have ceiling joist cut out the double plate. run the pipe thru the roof then install a long nail plate across the cut. the exterior plywood sheathing and the joists will keep it from moving. if its a vaulted ceiling you'd have to check if you have a weight bearing ridge before cutting.
    post a pic or give more info.
