How do I remove a 4 inch threaded brass plug from cast iron soil pipe. Obviously it is old and corroded.:mad:

I would try heat and "Blaster" penetrating oil.
If all else, drill it out, start with a small hole as centered as you can, then drill larger without hitting threads, then try to fold in what's left of the plug.

Thanks Stratmando... I was thinking along the same lines and you're right, last resort is folding it in away from the threads. I'll give it a try, must remember to get a new pvc plug for it though! :)

Strat gave you one option. Let me tell you the way I remove a brass clean out cover. If they hang up when I put a wrench on them I take a chisel and see if I can start it out counterclockwise, (see image). If that fails I take my hammer and whack it in the center until it breaks apart. Then that sucker comes out in pieces. New covers are cheap and easy to locate so no worry about replacement. Good luck, Tom

Another great idea! Thanks Tom!

I like Tom's option. You will most likey have to either break it or use hammer and chisel to break the seal. If you still want to use wrench - and you have the luxury of space - rent a 36" wrench from Home Depot and try to turn it.
