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
get an "ID" (that is Inside Diameter) pipe wrench. they are available at most good hardware stores. this will allow you to turn the flange from the inside.
I would take out the lead bend and replace it with pvc.
pvc flange if glued properly can not be detached you just need to cut it and fix up a new one if the old flange is useless. www.pvcpipe.in
The bolts that come from the drain and run to to toilet help to alaign proper drainage and seal the toilet. You do not want to do the bolts set in cement idea...
Usually toilet flange is glued down onto plastic drain pipe. There is a toilet flange that can be glued inside of plastic drain pipe also.
To allow floor flange bolts to have a place to fit and to anchor the flange to the cement /wood decking
Probably the wrong size flange. Is the flange a toilet collar? If so the pipe is probably 4 inch.
flange off tool.....Locke Supply carries them
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.
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.
The flange connects to the shower and just goes through the floor. It shouldn't mount to the floor.
Yes, be sure to pipe floor drain line properly into water closet piping.
