    Raise closet flange on cast iron pipe
    I am installing a new hardwood floor in my bathroom and a new wc. The waste line is cast iron.
    What is the simplest way to raise the flange the 3/4" (I think) to accommodate the new floor?
    Thanks

    If we're talking only 3/4 of an inch, then you can get by using a single fatter wax ring with a plastic horn and 1 regular one without a plastic horn.

    Yep, doubling would work fine or you could add a PVC spacer ring on the flange.

    A PVC spacer would be even better.
