How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 2 of 10
In this video
The final method shown is using a standard metal tube cutter, often used for copper pipes. The narrator suggests this as an 'in a pinch' method. The cutter is clamped onto the pipe, and the user rotates it around the pipe, tightening the knob slightly with each rotation until the cutting wheel cuts through. This method works on smaller diameter PVC but is slow. It does, however, produce a clean, square cut.
Goal: Cut small-diameter PVC pipe when no other specialized tools are available.
- This is a good method to use 'in a pinch' if you already own a tube cutter for metal pipes.
- This method is much slower than other options and is limited to smaller pipe diameters.

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.
