Step 2 · Mark and Cut the Damaged Section
Precisely mark the section of pipe to be removed. Identify the pinhole leak or crack. Using a tape measure and a permanent marker, mark the pipe on both sides of the damaged area. You need to cut out a section large enough to remove the damage completely. For this repair, we will use a push-to-connect slip coupling, which requires a specific size gap. Check the instructions for your slip coupling; typically, you need to cut out a section of pipe that is about 2 inches longer than the coupling itself. This allows the slip end to slide fully onto the pipe before being slid back. Once marked, use a tubing cutter for a clean, square cut. Place the cutter on the mark, tighten it slightly, rotate it around the pipe, tighten again, and repeat until the pipe is cut. Repeat for the second mark. Wear safety glasses to protect your eyes from any metal filings.
