Tools and Materials You’ll Need
- Copper pipe (1/2-inch or 3/4-inch)
- Pipe cutter
- Flux
- Solder
- Soldering torch
- Wet/dry vacuum
- Plumber’s tape
- Basin wrench
- Adjustable wrench
- Hacksaw
- Safety glasses
Step 1: Prepare the Work Area
Turn off the water supply to the sink and open the faucet to release any remaining water. Place a wet/dry vacuum under the sink to catch any water that may drip during the repair.
Step 2: Cut the Old Pipe
Use a pipe cutter to cut the old copper pipe at the desired location. Make sure the cut is clean and perpendicular to the pipe.
Step 3: Clean and Flux the Pipe
Clean the cut ends of the pipe with sandpaper or a wire brush to remove any dirt or debris. Apply flux to the inside and outside of the pipe ends. Flux helps the solder flow smoothly and creates a strong bond.
Step 4: Solder the New Pipe
Place the new copper pipe into the fitting and secure it with a basin wrench. Apply heat to the joint with a soldering torch and melt the solder into the joint. Hold the torch steadily until the solder flows around the entire joint.
Step 5: Inspect the Solder Joint
Once the solder has cooled, inspect the joint for any leaks. Apply more solder if necessary.
Step 6: Reconnect the Sink
Reconnect the sink to the new copper pipe using plumber’s tape on the threads. Tighten the connection with an adjustable wrench.
Step 7: Turn on the Water Supply
Turn on the water supply and check the joints for any leaks. If you notice any leaks, tighten the connections or apply more solder.

A: Flux helps the solder flow evenly and prevents oxidation, creating a stronger and more durable joint.
Q: What should I do if I can’t solder the joint?
A: If you have difficulty soldering the joint, you can use a compression fitting or a sharkbite fitting as an alternative.
Q: How long will the repair last?
A: Properly soldered copper pipe joints can last for decades with minimal maintenance.
Q: Can I replace copper pipe with PEX pipe?
A: Yes, you can replace copper pipe with PEX pipe. However, you will need to use special fittings designed for connecting copper and PEX pipe.
Q: What are the benefits of replacing copper pipe?
A: Replacing old or damaged copper pipe can improve water flow, reduce leaks, and increase the lifespan of your plumbing system.
