How to Remove Copper Pipe from the Brass Valve

If you’ve ever done plumbing work, you know that getting copper pipes out of brass valves can be extremely tricky. It requires precision and patience, but it can be done. In this blog post, we’ll walk you through the step-by-step process of removing a copper pipe from a brass valve, so you can get the job done quickly and correctly. Let’s get started!

Step 1: Gather Your Tools

Before you begin, ensure you have all the tools necessary to complete the task. You will need an adjustable wrench, a pair of pliers, and some lubricant like WD-40 or Liquid Wrench. Having these tools handy will make the job much easier.

Step 2: Prepare the Pipe

Once your tools are in order, it’s time to prepare the pipe for removal. Use the adjustable wrench to loosen both ends of the copper pipe until they come apart quickly. Make sure not to tighten them too much, or it could damage the valve and make removal more difficult. Once they are loose enough, use your pliers to gently twist each end of the pipe until it comes apart completely.

Step 3: Lubricate

Now that the pipe is off, it’s time to lubricate it. Apply generous amounts of WD-40 or Liquid Wrench onto both ends of the valve and let it sit for 15 to 20 minutes before attempting to remove it again. This will help break down any residue or corrosion that may have formed around the connection point between the copper pipe and brass valve over time.

Step 4: Remove the Valve

Once your lubricant has had time to work its magic, use your adjustable wrench to loosen both ends of the copper pipe again until they come apart easily. Once they are loose enough, carefully twist each end with your pliers until they come off completely from either side of the valve body. When loosening one side of a valve body with an adjustable wrench, always turn counterclockwise as this prevents accidental damage due to over-tightening on one side while loosening on another side simultaneously with another tool or hand grip hold pressure applied by hand in the opposite direction simultaneously turning action at the same time which can lead to tightening within itself causing permanent damage where then must be cut off replaced removed with a new part instead for further repair work if necessary for new installation altogether sometimes depending on the situation at hand.


Removing a copper pipe from a brass valve is not an easy task; however, by following these steps carefully and patiently, you should be able to complete this job without too much difficulty. With patience and proper technique, anyone can remove a copper pipe from a brass valve in no time! Good luck!
