: My task was to replace a shower head. While removing the shower head the chrome extension broke off (it comes from the copper pipe in wall). There is a broke off piece of pipe in the elbow at the end of the copper pipe. How can I remove this broke piece to install a new chrome extension? I do not want to cut off the elbow unless absolutely necessary. It is back in the wall behind a built in shower stall and I do not have much access to it.
