How to Repair a Leaking Copper Pipe with a Compression Coupling · Step 1 of 7
In this video
Before starting the repair, shut off the main water supply to the house. Attach a hose to the leaking drain valve and direct the other end to a bucket or drain. Slightly open the valve with an adjustable wrench to allow the system to drain completely. This prevents a mess when you fully disassemble the valve.
Goal: Drain the system
- Ensure the main water stopcock is fully closed before proceeding.
- Wait until water completely stops flowing before removing the valve stem.

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.
