Can a cast iron clean out plug be loosened?
Cast iron has a tendency to rust, so drainpipe plugs that have not been removed in some time may seem molded to the pipe by rust. Loosening a cast iron clean-out plug from a drainpipe requires softening the rust enough to break it free. Spray the perimeter of the cast iron clean-out plug with penetrating lubricant.
What to use to clean out cast iron pipe?
Spray the perimeter of the cast iron clean-out plug with penetrating lubricant. Spray the seam between the plug and the inside of the cast iron pipe. Allow the penetrating lubricant to work for 30 minutes. Scrub the seam between the plug and the pipe with a steel wire brush.
What’s the best way to remove a stuck cleanout plug?
Hold the new pipe in place and slide the vertical coupler into place and snug it up. Then connect the horizontal coupler. Tighten both to the proper torque. Saw through the horizontal pipe, but leave about 1/4 in. of the pipe uncut. Then saw off the vertical pipe. The horizontal “tab” prevents the vertical pipe from wiggling while you saw.
What do old cast iron drain plugs do?
Many older homes still have old cast iron drain and sewer pipes rather than the PVC plastic pipes used in modern home construction. The end of the drain pipe has a removable cap plug. This plug allows access to the drain pipe for removing clogs and other obstructions.

What’s the best way to remove a cleanout plug?
You can try heating the cast iron that the plug is in with a propane torch to see if that will loosen it, OR you can soak the threads (at least overnight) with a good penetrating oil, and then use a length of “cheater” pipe (galvanized) that will fit over the handle of a large pipe wrench to try and break it loose counter-clockwise. Good Luck!
