I have 6" CI pipe that has a 3" brass cap for clean out access. It's 40 years old. How can I remove it?
As I remember, in my old house when I had the sewer line rodded out they used a cold chisel and 3-lb hammer to push the cap part way in to break the thread seal then a large pipe wrench to screw it out.
Before I use this brute force approach are there any other methods? thanks bob
