Sweating copper pipe is a common plumbing technique that involves joining two pieces of copper pipe together using heat and a flux material. It’s a simple and effective way to create a strong, leak-free connection. Copper is a good choice for plumbing because it is corrosion-resistant, durable, and readily available. Sweating copper pipe is a relatively simple process, but it does require some specialized tools and materials. Once you have gathered the necessary supplies, you can follow these steps to sweat copper pipe.
First, you will need to clean the ends of the copper pipes that you want to join. This can be done with a wire brush or sandpaper. Once the pipes are clean, you will need to apply a flux to the ends of the pipes. Flux is a chemical that helps to clean the metal and promote the flow of solder. Once the flux has been applied, you will need to heat the ends of the pipes with a propane torch. When the pipes are hot enough, you will need to apply solder to the joint. The solder will melt and flow into the joint, creating a strong, leak-free connection.
Sweating copper pipe is a simple and effective way to create a strong, leak-free connection. However, it is important to use caution when working with heat and solder. Always wear safety glasses and gloves, and be sure to work in a well-ventilated area. With a little practice, you can master the technique of sweating copper pipe and make professional-quality plumbing repairs.
Heating the Copper Pipe with a Propane Torch
To solder copper pipe, you’ll need to heat the pipe with a propane torch. Here are the steps to do that:
1. Prepare the torch
Make sure the torch is filled with propane and that the tip is clean. If the tip is clogged, use a torch cleaner to clean it out.
2. Adjust the flame
Adjust the flame to a medium-blue color. A yellow flame will not be hot enough to solder the pipe, and a white flame will be too hot and can damage the pipe.
3. Heat the pipe
Hold the torch about 6 inches away from the pipe and move it back and forth slowly. Heat the pipe evenly, making sure to heat the entire circumference of the pipe. You can check the temperature of the pipe by touching it with a wet finger. If the pipe is hot enough, the water will sizzle and evaporate immediately.
### 6. Apply flux
Once the pipe is hot enough, apply flux to the area you want to solder. Flux is a chemical that helps the solder flow smoothly and bond with the pipe. Apply a thin, even layer of flux to the pipe.
Flux Application Techniques
| Method | Description |
|---|---|
| Dipping | Submerge the heated pipe end into a flux container. |
| Brushing | Use a flux brush to apply flux to the heated pipe. |
| Paste Application | Apply a thin layer of paste flux to the heated pipe using a cotton swab or finger. |
How To Sweat Copper Pipe
Sweating copper pipe is a process of joining two pieces of copper pipe together using solder. The solder is melted and flows into the joint, creating a strong, permanent bond. Sweating copper pipe is a relatively simple process, but it does require some basic tools and materials.
To sweat copper pipe, you will need the following:
- Copper pipe
- Solder
- Flux
- Heat source (such as a propane torch)
- Pipe cutter
- Sandpaper
- Wire brush
Once you have gathered your tools and materials, you can begin the process of sweating copper pipe. First, you will need to cut the copper pipe to the desired length. Use a pipe cutter to make a clean, square cut.
Next, you will need to clean the ends of the copper pipe. Sand the ends of the pipe with sandpaper to remove any dirt or debris. Then, use a wire brush to clean the inside of the pipe.
Once the ends of the copper pipe are clean, you will need to apply flux to the joint. Flux is a chemical that helps the solder to flow into the joint. Apply a thin layer of flux to the inside of the pipe and the outside of the fitting.
Now you are ready to heat the joint. Use a propane torch to heat the joint evenly. Heat the joint until the solder melts and flows into the joint. Be careful not to overheat the joint, as this can damage the copper pipe.
Once the solder has cooled, the joint will be complete. Allow the joint to cool completely before handling it.

How do you sweat copper pipe without a torch?
You can sweat copper pipe without a torch using a soldering iron. However, this method is not as effective as using a torch, and it is only recommended for small joints. To sweat copper pipe without a torch, follow these steps:
- Clean the ends of the copper pipe as described above.
- Apply flux to the joint.
- Heat the joint with a soldering iron until the solder melts and flows into the joint.
- Allow the joint to cool completely.
