Preparing the Copper Pipes and Fittings
1. Cut the Copper Pipes: Use a copper pipe cutter to make clean, square cuts.
2. Ream the Pipe Ends: Use a reamer to remove any burrs or sharp edges from the pipe ends.
3. Clean the Pipe Ends: Wipe the pipe ends with a clean cloth to remove any dirt or debris.
Applying Flux and Solder
1. Apply Flux: Apply a thin layer of flux to the inside and outside of the pipe ends and the fitting. Flux helps to remove oxides and ensures a strong bond.
2. Tin the Pipe Ends: Dip the pipe ends and the inside of the fitting into a small amount of solder to create a thin coating.
Soldering the Copper Fittings
1. Position the Fitting: Insert the fitting into the pipe ends and align them correctly.
2. Heat the Joint: Use a soldering torch to heat the joint evenly, starting from the bottom and working your way around.
3. Apply Solder: Feed solder into the joint while heating it. The solder will flow into the joint and create a strong bond.
4. Cool the Joint: Allow the joint to cool completely before moving on.

Additional Tips for Flawless Fittings
- Use a Pipe Wrench: Tighten the fittings securely using a pipe wrench, but avoid overtightening.
- Apply Plumber’s Tape: Wrap plumber’s tape around male threads to create a watertight seal.
- Test for Leaks: After completing all the fittings, turn on the water supply and check for any leaks.
Advanced Techniques
1. Sweating Copper Fittings: A technique that involves heating the fitting and applying solder without flux.
2. Brazing Copper Fittings: A stronger and more durable method that uses a higher-temperature torch and a silver-based brazing alloy.
Troubleshooting Common Issues
1. Leaks: Check for loose fittings, damaged pipes, or insufficient solder.
2. Cold Joints: The joint did not reach the proper temperature for soldering.
3. Overheated Joints: Too much heat can weaken the joint and cause leaks.

Answers to Your Most Common Questions
1. What is the best type of solder to use for copper fittings?
95/5 solder, which contains 95% tin and 5% antimony, is recommended for copper pipe fittings.
2. How long should I allow the joint to cool before moving on?
Allow the joint to cool for at least 10 minutes to ensure a strong bond.
3. Can I use any type of flux?
No. Use a flux specifically designed for copper pipe fittings. Acid-based fluxes can damage copper.
4. What should I do if I have a leak?
Identify the source of the leak and apply more solder to the affected joint. If the leak persists, consult a professional plumber.
5. How often should I check my copper pipe fittings for leaks?
Inspect your copper pipe fittings every few months, especially after any major plumbing work or changes in water pressure.
