How to Resolder Copper Fittings

Most plumbing fixture tubes and fittings are either PVC or copper. While PVC requires a special glue to adhere two pieces together, copper is soldered together. Soldering is the process where metal wire is melted into place along the connecting joint of two copper pieces. When it dries, it creates a waterproof pond. You may find it necessary to resolder the copper fittings as the bond wears down over time.

Things You'll Need

• Propane torch
• Lead-free solder
• Lighter

Instructions

1. Wipe the area around the copper fittings.

2. Turn on the propane torch. You will hear a slight hissing noise from the gas released from the torch. Light it by holding the flame from a lighter up to the edge of the propane torch. Adjust the size of the flame with the small knob on the handle of the torch.

3. Hold the propane torch close to the copper fittings and run it back and forth around the fitting. Take the lead free soldering wire and unwind a small piece of it. Insert the wire into the flame. It will melt along side the fitting of the two copper pipes.

4. Direct the solder with the unmelted soldering wire. Make sure it runs all the way around the pipe. Wait until the copper has cooled to the touch. You now have a water-resistant resoldered copper fitting.

Tips & Warnings

• Make sure to use a lead-free soldering wire. If you solder the copper fittings to a pipe that takes water to a faucet (such as your kitchen), you do not want to take the chance of contaminating the water with lead.
