cap underground copper pipe
How does one cap a buried copper pipe? I have underground pipes to my detached garage. The pipe branches underground for sink, toilet and there is a branch to a tap in the middle of the yard. The last one has to go. I dug up some parts of the pipes today. They look to be pretty rough from corrosion on the outside so soldering a cap on them looks like it will not be possible. I have not yet tried a wire brush or anything like that.
