I have plastic pipe now & want to put copper pipe to avoid any leakage -
I have plastic and have NEVER had a problem. Plastic is nice because it does not kink --
If you are talking about the water line that feeds the refrigerator, I wouldn't suggest changing it to copper, simply because the plastic hose is more flexible and won't crack if bent in the same place repeatedly. If you are set on making the change, make sure that you can do so without pinching or kinking the copper line (this includes when you push your fridge back into place). The copper fittings are similar to the plastic, as both plastic and copper line make use of compression type fittings. Make sure to get the same size pipe as the old hose with the proper fittings. You can get these by asking for assistance at most hardware stores. You will need a reaming tool to make sure the copper pipe flares at the end and is smooth. This may also be obtained at most hardware stores. Then cut to the pipe to the proper length, make sure you have smoothed and flared both ends of your pipe, connect the pipe to the valve and the refrigerator, and make sure to tighten both fittings properly. Not very hard. Make sure to watch your fittings for a while to make sure you don't have any leaks before pushing your fridge back in place. If you are referring to a different pipe then I would also say good luck!
