Step 2 · Mark and Cut the Damaged Pipe Section
Precisely measure and mark the section of pipe that needs to be removed. Identify the exact location of the pinhole leak. Using a permanent marker, make a mark at least 1 inch to the left and 1 inch to the right of the damaged area. This ensures you are working with a solid, undamaged section of pipe. Place a tubing cutter around the pipe on one of your marks, tighten it slightly, and rotate it around the pipe, tightening the knob with each rotation until the pipe is cut cleanly. Repeat this process on the second mark to remove the damaged section entirely.
