Hi,
My cast iron toilet flange broke at the bolt areas and looks like it was never replaced. The house is 50 years old. The pipe is cast iron as well and measures 4-1/4" OD and 3-1/2" ID. I removed the old flange and noticed there was what appeared to a lead seal holding it in place. Based on the information I've supplied, can you give me some suggestions on what size cast iron of flange I should buy, methods to secure it onto the pipe and general tips on how to install a new flange... i.e. special sealants, tools, et..
Thank You

Let's first of all get rid that lead and oakum joint. To remove a poured lead and oakum joint take a 3/8" drill bit and drill a few holes down past the lead and into the oakum.. Push a screwdriver under the lead ring and lever it up. Once it's free you can began to peel the lead ring out. Now pick out the oakum and you can pull the joint apart and rfemove all of the old flange.

Boy! Are you lucky. I have just what youi need. I can't tell you what size your pipe is, either 3 or 4 inches. Based on the age of the system I would guess 4" but measure yourself.
Now comes the part you're gonna love. I have a cast iron flange in either 3 or 4 inch that requires no special tools or skills to install. Paste up; plumbingstore.com on your search bar and scroll down to "Torque Set Closet Flange" Hope this helps, Tom
