Broken Cast Iron Flange
Posted by Sebastian Formoso on June 26, 2001 at 11:49:53:

We just bought our first home. To our surprise, the toilet in the master bathroom leaked at the base when flushed.
When the tile installers removed to toilet to lay tile underneath, they found that the cast iron flange is so badly rotted that it simply
falls to pieces. I called a few plumbers but their quotes are outrageous.

If I decide to take this project on how should I proceed? Should I cut out the existing cast iron flange a few inches from the floor's surface
and then install an expanding PVC flange or just clean up the corroded iron at the surface of the floor and slide a PVC flange over the cast iron pipe.

We have a terrazzo floor underneath the tile so I am not dealing with a wood floor. I would assume that I could just slide the PVC flange into place.

What are your suggestions for making this a DIY project; should I even dare?
