Deburr and Prepare Copper Pipe End

What happens here

After ensuring that the copper pipe extends approximately three inches from the wall, allowing sufficient length for potential future repairs or modifications, carefully deburr the inside edge of the pipe. Use a thin-bladed utility knife to scrape away any burrs or sharp edges left from cutting. Following this, take a piece of cloth and use it to clean any loose debris or metal shavings from the pipe's opening.

Goal: Smooth and clean the cut end of the copper pipe to ensure proper fitting and solder flow.
