How to Remove Compression Fittings

Most plumbing fixtures that may eventually be replaced use compression fittings. Faucets, toilets, dishwashers and refrigerators with ice makers or drinking water dispensers use compression fittings father than soldered pipes because of their ease of removal for replacement of the appliance. Because the ferrule inside the fitting makes a permanent connection to the copper tubing, it may be reused in some cases. But the best bet is to cut off the old ferrule and replace it with a new one.

Things You'll Need

• Wrench
• Copper tubing cutter or hacksaw

Instructions

1. Shut off the water supply to where you will remove the fitting.

2. Remove the nut from the back or the compression fitting by turning it counterclockwise with the wrench.

3. Slide the nut up the copper tubing out of the way.

4. Pull the copper tubing out of the valve or appliance to which it is connected.

5. Cut the copper tubing as close to the ferrule as you can, using the tubing cutter or the hacksaw. If you want to try to use the connection again, skip this step.

Tips & Warnings

• Be careful not to bend or dent the copper tubing while removing or cutting it because you may not be able to put on a new ferrule.
