sometimes you can break the bond by actually tightening it first if not drill and/or cut it out.Then replace it.

When I was with roto - rooter a while back this was a common occurrence. We always would use a cold chisel, making a notch in the brass and then chiseling it out counterclockwise and then replacing with pvc.

Hope that helps and good luck.

I have a problem with that too. I am not a cleaning expert though to think I am a woman and I find it hard to really scrub off clean my bathroom. I really hate all the dirt (call me an OC, yes I am). One time my drain got stuck with all the hair,water was flooding outside the shower area and my glass door went so scum-filled crap. I just can't take it! Hope all these tips would help me..

Brass being softer then cast iron but not as brittle care has to bew taken when using a cold chisel. You maybe better off heating the CO agaion but this time use a wax candle as a lube and it should then be able to be removed with a wrench.

I would advice you to use drill cutter to cut these plugs from the sockets but take care about the cutter speed otherwise it can penetrate the pipe that will create problems for you.
