How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 3 of 10
In this video
After cutting, carefully remove all burrs from the inside and outside of the pipe end. Burrs are small shavings or raised edges of plastic left from the cutting process. You can use a dedicated deburring tool, a utility knife, or a file to create a smooth, clean edge. This step prevents the burrs from scraping away the cement during assembly.

FAQs
What are the most critical safety precautions I need to take when soldering copper pipes?
Always wear safety glasses and gloves to protect from heat and flux. Ensure adequate ventilation, keep a fire extinguisher or bucket of water nearby, and use a heat shield (like the Oatey 9 in. x 12 in. Hands-Free Solder Heat Shield) to protect surrounding flammable materials from the torch flame and hot pipes.
Why is cleaning and deburring the pipe and fitting so crucial before applying flux and soldering?
Thorough cleaning with a fitting brush and sandpaper removes oxides and contaminants, which are essential for the solder to properly flow and adhere via capillary action. Deburring with a tool like the Husky 1-5/8 in. Inner/Outer Reamer ensures the fitting seats correctly and prevents turbulence in water flow, promoting a perfect solder joint.
How do I know I'm using enough solder, and what commonly causes a joint to leak after soldering?
You've used enough solder when you see a complete, continuous ring of solder around the joint's circumference, indicating full capillary fill. Leaks are often caused by insufficient or uneven heat application, improperly cleaned surfaces, or applying too little solder, which results in an incomplete or 'cold' joint.
Can I use a regular propane torch, or do I need a MAPP gas torch for soldering copper pipes?
While a basic propane torch might suffice for smaller pipes (1/2" - 3/4"), a MAPP gas torch (such as the Flame King High Intensity Propane Torch Head) provides a hotter flame. This is more efficient for larger pipes and quicker heating, reducing the risk of overheating the pipe or burning off the flux prematurely, which are common beginner mistakes.
