How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 1 of 9
In this video
With the new fittings prepared, solder the assembly in place. Slide the prepared elbow onto the existing copper pipe coming from the shutoff valve. Protect the wall and any nearby flammable materials with a wet rag or heat shield. Heat the joint with the torch until it's hot enough to melt the solder. Apply the solder to the joint, allowing it to wick all the way around and create a complete seal. Be careful not to set the wall on fire.
Goal: Plumbing Pipes Repair (Leaking)
- The video shows the wall getting scorched. Always use proper heat shielding to prevent fire.
- Heat the brass valve body more than the copper pipe, as brass takes longer to heat up.
Used in this video
- Propane Torch (brand: Bernzomatic) — Heating the copper pipe and brass valve for soldering.
- Wet Rag — Protecting surrounding surfaces from the torch flame and cooling the joint.

FAQs
What are the most important safety precautions when soldering copper pipes with a propane torch?
Always work in a well-ventilated area to avoid inhaling fumes from the flux and solder. Wear safety glasses and heat-resistant gloves, and keep a fire extinguisher or a bucket of water nearby as a precaution against accidental fires. Ensure no flammable materials are within the K Tool International Self Igniting Propane Torch's reach.
Is lead-free solder mandatory for plumbing, and why is flux so important for a good joint?
Yes, lead-free solder is legally required for plumbing potable water systems in most regions to prevent lead contamination in drinking water. Flux is crucial because it cleans the copper of oxidation and prevents new oxidation during heating, allowing the Oatey Safe Flo Lead-Free Silver Solder to flow properly via capillary action, creating a strong, watertight bond.
My solder isn't flowing into the joint, or it's beading up on the outside. What am I doing wrong?
This usually indicates insufficient or uneven heat. Ensure you are heating the fitting, not just the pipe, and letting the heat transfer until the copper itself is hot enough to melt the Oatey Safe Flo solder on contact, not the torch flame directly. Also, verify that all surfaces were thoroughly cleaned with 3M emery cloth and the HDX 4-in-1 Fitting Brush, and properly coated with Oatey H-20 Lead-Free Water Soluble Solder Flux Paste.
How difficult is soldering copper pipes for a beginner, and how much time should I allocate per joint?
Soldering is a beginner-friendly plumbing skill, but it requires some practice to master the heating technique. With proper preparation and the right tools like the K Tool International Self Igniting Propane Torch, a single joint can typically be soldered and cooled in about 5-10 minutes, not including initial pipe cutting and cleaning.
