When it comes to the plumbing system in your home, there are certain repairs you can do yourself such as replacing the faucet, unclogging the sink or unsoldering the copper pipe. Occasionally, you need to get into the pipe work or maybe, you need to replace a straight coupling and replace it with a T-joint. Another reason to remove the old joints is if there is a leak in the soldered joints.

How to Unsolder Copper Pipe

Unsoldering the copper joint can be done by applying high heat over the copper coupling or connection that needs to be detached. This process takes several steps to finish. First, you need to have the necessary tools to get the work done easily and accurately.

Tools Needed

Propane Torch
This is the tool you will need in both soldering and unsoldering the copper pipe. It has a regulator and a tip that will be attached to a small tank. There are torches with built-in igniters and ones that require a match or lighter to ignite.

Soldering Pliers or Pipe Cutter
You will need this when you solder back the new copper fitting or T-joint.

Flame Shield
If you are working in a wooded area, a flame shield will come in handy.

Safety Goggles
Once the solder has melted, the fluid from the copper can burst and hit your eye so it is important to wear eye protection.

Unsoldering Procedure

Tip: If you are replacing a coupling joint on a copper pipe, make sure that all the water in the pipe has been drained since failing to do so will prevent the solder from melting from the heat.

Unsoldering is a very common procedure especially in fixing plumbing problems. With the right tools and correct procedure, you can replace or repair copper pipes with ease.
