I am renovating a house my daughter bought and thought I had a helper that knew what he was doing because I don't! When we removed the four layers of flooring in the bathroom to install a tile floor, my helper broke the toilet flange. And we proceeded to cut it off (we didn't have much pipe to work with) near the T coming out of the main drain stack. It is ABS material. My helper thought the white stuff (PVC) could be attached to the ABS (which it could) but we didn't use the Oatley stuff. Even though it seems to have taken, do I have to redo it all? If I do, then that leads to a bigger issue, there is little (maybe an inch) left of ABS coming out of the T. Is that enough to glue the coupling to it to extend the other parts up to the flange? If not, short of cutting out the T which I really don't want to do, is there another solution?

To answer your question I need more details. How much distance between the inch of pipe out of the branch of the tee up to the finished floor line? Do you have the PVC flange installed? If so why are you asking about adding a raiser to the tee? Regards, Tom
