Use a PEX removal tool or slotted screwdriver to remove the coupling
PEX (cross-linked polyethylene) fittings are commonly used in plumbing due to their flexibility and durability. Removing them from plastic can be challenging if you don't have the right tools and techniques.
A PEX removal tool or a slotted screwdriver can be used to remove the coupling. First, determine if the fitting is a crimp or clamp type. Crimp fittings have a smooth, round surface, while clamp fittings have a raised ring around the edge.
If you are using a PEX removal tool, follow the manufacturer's instructions for its use. These tools are designed to make removing PEX couplings easier and safer.
If you are using a slotted screwdriver, you will need to carefully cut the crimp ring with pliers or a utility knife. Ensure you do not damage the brass barb fitting or the PEX pipe itself. Once the crimp ring has been cut, use the screwdriver to pry it open, allowing you to remove the fitting from the pipe. If needed, use pliers to grip the pipe and twist it off.
Always wear gloves and safety glasses when working with PEX couplings, as sharp tools and hot surfaces can cause injury.

Use a pipe cutter to cut off the piece that was on the coupling
When removing a PEX coupling, it is recommended to cut off the piece that was on the coupling to start fresh and eliminate the risk of future issues. Here is a step-by-step guide on how to use a pipe cutter to cut off the piece that was on the plastic PEX coupling:
First, ensure you have the right type of pipe cutter for the job. There are various types of pipe cutters available, including scissor-type, ratchet-style, and C-shaped cutters. Choose the cutter based on the diameter of the pipe and the number of cuts you need to make. For example, scissor-type cutters are suitable for small pipes with a diameter of 1 inch or less, while ratchet-style cutters can handle larger diameters of up to 1.5 inches. If you need to make multiple cuts, a power miter saw may be a better option.
Next, prepare the pipe for cutting. Mark the pipe using a pencil or marker to indicate the cut location. If using a miter saw, secure the pipe under the saw blade at the workbench. If using a pipe cutter, clamp the pipe into place with a vise to hold it steady and prevent slippage. Put on the necessary safety gear, including eye protection and gloves, before proceeding.
Now, you're ready to start cutting. For ratchet-style cutters, arrange the blade over the mark and squeeze the handle. Release the handle and repeat the ratcheting action until the pipe is cut in two. With scissor-type cutters, squeeze the hand-grip trigger to extend the blade and cut through the pipe. If using a miter saw, slowly bring the blade down onto the marked location and activate the saw. Cut through the pipe, then turn off the saw and wait for the blade to stop spinning before removing the pipe.
Finally, deburr the pipe to ensure a smooth edge. Use a deburring tool or a utility knife to remove any shavings or particles left on the pipe after cutting. This step will help ensure a better connection when gluing the pipe to another section.
By following these steps, you can effectively use a pipe cutter to remove the piece that was on the plastic PEX coupling, allowing you to start fresh with a secure and reliable connection.
