Can You Unsolder Copper Pipe?

Unsolder Copper Pipe

Working with copper pipes can be intimidating for those unfamiliar with the process. If you’re planning to do any plumbing work in your home, one of the most important questions you may have is, “Can you unsolder copper pipe?” The answer is yes, but it can be tricky and time-consuming if you don’t do it properly.

Soldering vs. Unsoldering Copper Pipes

Soldering is joining two pieces of metal together using a special solder alloy. This alloy is melted at high temperatures and then placed between the two pieces of metal to form a secure bond. Unsoldering, on the other hand, is the process of removing solder between two pieces of metal so they can be separated. It’s important to note that this process cannot be done without damaging the pipes, so it’s best to approach this task cautiously.

Preparing for Unsoldering Copper Pipes

Before attempting to unsolder copper pipes, several steps need to be taken to ensure a successful outcome. First, ensure that all water sources connected to the pipe are shut off and no water is running through it. Then, use an adjustable wrench or pliers to loosen any fittings attached to the pipe. Once these steps have been completed, you can begin unsoldering the pipe.

How to Unsolder Copper Pipe

The first step in unsoldering copper pipes is heating the joint with a torch or soldering iron until it begins to glow red hot. Once this has been done, apply flux paste around the joint before inserting a hollow tube called a pickle into it (this tool helps break down oxidation on metals). Finally, use a soldering iron or pliers to remove any remaining solder from inside the joint and separate it from its neighboring pipe. Unsoldering copper pipes can be done safely and successfully with proper preparation and care!

  • Turn off the water to the pipe that you will be soldering.
  • Use a propane torch to heat up the area where the copper pipe and fitting meet. You will want to heat the area until it is glowing red.
  • Apply flux to the heated area. Flux helps to clean the surfaces and promote a stronger bond.
  • Place the solder on the heated area. The solder will melt and flow into the joint, creating a seal.
  • Allow the joint to cool before turning the water back on


Unsoldering copper pipes can seem intimidating at first glance, but with proper preparation and patience, anyone can do it successfully! Before attempting this project on your own, make sure that all necessary safety precautions are taken and that you understand what needs to be done before beginning work on any plumbing project in your home. With knowledge and practice comes confidence—and trust is key when working with copper piping!
