I removed the broken flange by perforating the lead filling between the drain pipe and the flange - i.e., drilling holes every 1/4-1/2 inch or so with a regular drill and then sawing through the filling with a power saber saw. Then pried the flange off with a pry bar. Wasn't as bad as I expected. - Dan

Can you remove a toilet and floor over drain?

The toilet flange is usually above the floor level. You would have to cut it off the drain pipe and cap it. How you do this depends on what type of pipe the drain is made of. Even if the drain should be below the floor level, you have to seal the drain or sewer gas will come up from the drain.


How do you relocate a drain in a concrete slab?

Change how? Move the location, you bust out the concrete and move it. Replace or repair the flange that the toilet hooks to. Cut the existing flange off flush with the floor and install a new repair flange. They can be brass or steel. You can use a PVC one that fits in the drain and seal it with a wax ring under it and screw it to the floor. If you are working with cast iron flange and the slots where the bolts are supposed to go is broken out, they make a repair piece for this. It is a 3/4 inch wide by 3-4 inch long crescent shape piece that slides under the flange and the bolt that holds the toilet fits into it. You may have to chip out a little concrete along the edge to get these under the flange.
