Cut the Pipe — Cut Out the Damaged Section
Part of project
How to Repair a Leaking Copper Pipe with a Compression Coupling · Step 3 of 7
In this video
Using a manual pipe cutter, the pipe is cut at a pre-marked location. The cutter is placed around the pipe and tightened until the cutting wheel makes contact. The tool is rotated around the pipe, and the handle is tightened incrementally (about a half turn per rotation) to slowly deepen the cut. This process is repeated until the pipe is severed, ensuring a clean and straight edge.
Goal: Make a Clean Cut on the Pipe
- Tighten the cutter gradually with each rotation to avoid damaging the cutting wheel and to ensure a smooth cut.

- Pipe Cutter (brand: Ridgid, Pipe Cutter Type: Manual pipe cutter) — Making a clean, perpendicular cut on the pipe before threading.

FAQs
How difficult is this repair for a beginner, and what if it takes longer than 3 hours?
This repair is rated beginner because it avoids complex techniques like soldering. While the estimated time is 3 hours, allow extra time for locating the leak, gathering tools, and ensuring the pipe system is fully drained. Rushing can lead to mistakes, so prioritize careful, precise work over speed.
Do I really need all the specific tools listed, or can I use substitutes for this project?
While tools like a dedicated tubing cutter and reamer are highly recommended for achieving clean, burr-free pipe ends crucial for a leak-proof seal, some items like permanent markers or measuring tape can be substituted with similar household tools. An adjustable wrench is essential, so ensure you have one that fits the coupling nuts securely.
What's the most common mistake beginners make with compression fittings, and how can I avoid a new leak?
The most common mistake is not properly preparing the pipe ends (cutting straight, deburring, and cleaning) or improperly tightening the compression nuts. Ensure pipe ends are perfectly smooth and burr-free, and tighten the nuts until snug, then give an additional 1/2 to 3/4 turn. Avoid over-tightening, which can deform the ferrule or strip threads, or under-tightening, which causes leaks.
What are the most important safety precautions I should take when repairing a leaking copper pipe?
Always shut off the main water supply and drain the pipes completely before starting to prevent water damage and potential electrical hazards. Wear safety glasses to protect your eyes from debris, especially when cutting or deburring the pipe. Be mindful of sharp edges on cut pipes.
