My closet flange broke and I have to knock out all the concrete to replace it. You can either call a plumber or get out the chisel and hammer.

It would realy help if one knew the type of materials your talking about XH CAST IRON CI flange, Brass flange attached to Lead, Plastic piping flange, No hub cast iron, galvanized steel.

It like me saying my car wont start please tell me why?

Thank you for looking and expressing interest. All the drains and stacks in my house are PVC. The subfloor is plywood and the bathroom is over finished space below. Worst case: I could cut out some sub-floor, cut out the flange and elbow and start from there. Do you have a better way? Thanks again for your help.

Shame you didn't ask first as many times one can use a Quick set flange or the one I tested and put on the Internet a great galvanized replacement type.

The key is the piping not necessarily the actual flange. Plastic even thought it is garbage in many cases it can be salvaged

There is something called a Quick set floor flange made of Cast Iron. Needs to be placed over the existing piping

It comes in several lenths and should fit over the bare pipe end, You can cut the old flange off close to the new finished floor

Here is a link tell them Tieger plumbing sent you (They may give you a better price)

To get the quick set you have to go to a plumbing supply not a home center
