Hi guys:
Does your flange look similar to the rusty picture below left?? If so..it originally looked like the flange next to that .
In this case, click on the
attached images: the clam2.pdf at the very bottom left of this post.
Here, you will need to cut off the entire ring (use aviation/tin snips) around the closet flange, then install the bivalve clam closet repair ring by installing it into the groove where the old ring was...see pic. by clicking on the attachment.
Then will simply need to secure the flange through the floor and should be all set to install the toilet.
The
CLAMSHELL closet repair ring can be found at almost all
PLUMBING SUPPLY HOUSES. You probably won't find these at a home supply store...go to a plumber's supply house and ask them...they should have it or something very similar. You may want to bring a picture with you...
If I am way off here....check out Ballenger's post...can always replace the entire flange if needed (may need an inside pipe cutter if decide to do this...see pic.). Just be sure to put a rag in the drain before using the inside cutter....just IN CASE the tool falls out of the drill while cutting...
Let us know what you think...
