cast iron offset flange

does any one kow were i could find a off set flange for my cast iron pipe. it is a 4 inch and is flush with my concrete right now......

i have seen some but they require me to break up the concrete to install and attach some type of flange. i would really like to get something that would sit inside the exsisiting pipe and not cretat more work... i now that might be hard but i must beleive there is something some were....thanks

The make PVC flanges that fit inside the pipe. I don't know for certain that there is one of these for cast iron, but I would be surprised if there wasn't. I think you need to go to a "real" plumbers' supply house rather than a Box Store. If there is one, they would have it. Perhaps one of the pros can answer this better than I.

There are no internal offset flanges for cast iron pipe. And because of the way they are installed and the leverages exerted, all of them have to be properly secured to the pipe, probably after altering the pipe to accept the offset.
