How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 1 of 9
In this video
Before starting, ensure you have all the necessary tools and have taken the proper safety precautions. Turn off the water supply to the area you'll be working on. Open a nearby faucet to drain any remaining water and depressurize the system. Gather your heat gun, utility knife, pliers, and heat-resistant gloves. Note that while brass ProPEX fittings are reusable, engineered polymer fittings are not.
Goal: System Preparation and Tool Gathering
- Brass fittings can be reused, but engineered polymer (plastic) ones cannot.
- Always ensure the water is off and the system is drained to prevent water damage and potential injury from hot water.

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.
