    Lowering a toilet flange
    Thank you!

    I need to lower 2 toilet flanges about 2 in. One is PVC the other copper, but both 3 in. I think I need to remove the old ones, cut the pipes and add a new flange. Is this correct? I think the new flanges will have to go inside of the 3 in. pipes. I hear that this is not ideal. Why is this? Is there a better option?

    That's right, unsolder the brass flange from the copper stub up and clean and save it.

    I prefer a outside flange if possible. The larger diameter opening on a outside flange gives better drainage. Good luck, Tom
