How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 4 of 9
In this video
The copper pipe end is thoroughly prepared for soldering. First, a deburring tool is used to clean the inside of the pipe. Then, emery cloth is used to sand the outside of the pipe until it is shiny and free of oxidation. The inside of the brass fitting is also cleaned with a wire brush. Finally, flux is applied with a brush to both the outside of the copper pipe and the inside of the brass fitting to facilitate solder flow and prevent oxidation during heating.
Goal: Create clean surfaces for a strong solder joint.
- A clean, well-fluxed joint is essential for solder to wick properly into the connection.
Used in this video
- Deburring Tool (Tool Type: Pipe cutter) — Cleaning the inside edge of the cut copper pipe.
- Wire Brush (Cleaning Tool: Wire Brush) — Cleaning the inside of the brass fitting.
- Flux Brush (Flux Applicator: Brush) — Applying an even coat of flux to the pipe and fitting.

FAQs
What type of torch is best for soldering copper pipes, and how do I know I'm applying enough heat?
The K Tool International Self Igniting Propane Torch Head is sufficient for most residential copper pipe soldering. You'll know you're applying enough heat when the pipe and fitting are hot enough to melt the Oatey Safe Flo Lead-Free Solder *by touching the pipe*, not the flame. The solder should then be drawn into the joint by capillary action.
What are the critical safety precautions I must take when soldering pipes indoors?
Always have a fire extinguisher nearby and remove any flammable materials from the work area, especially when using a torch. Ensure good ventilation to disperse solder fumes, and wear safety glasses to protect your eyes from splashes or heat. It's also crucial to turn off the main water supply before starting to avoid accidents and ensure pipes are dry.
Is it really necessary to deburr, ream, and thoroughly clean the pipes before soldering?
Absolutely. Deburring and reaming with a tool like the Husky 1-5/8 in. Inner/Outer Reamer ensures a smooth pipe interior for optimal water flow and prevents solder from being blocked. Thorough cleaning with sandpaper and applying Oatey H-20 Flux are critical to remove oxidation, allowing the solder to properly bond and create a strong, watertight seal.
What are the most common reasons a soldered joint might leak, and how can I avoid them?
Leaks often occur due to insufficient cleaning, inadequate heat application, or not using enough solder. Ensure pipes are shiny clean before applying Oatey H-20 Flux, heat the joint evenly until it can melt the solder, and feed enough solder to completely fill the joint. If a joint leaks, it must be desoldered, thoroughly cleaned, and resoldered.
