Step 4 · Measure and Cut the Replacement Pipe
First, measure the exact length of the gap created by removing the damaged section. Next, check the push-to-connect fitting's packaging or the fitting itself for the specified insertion depth (it is often 1 inch for 1/2-inch pipe). Add the gap measurement to two times the insertion depth (one for each fitting). This total is the precise length for your new piece of pipe. Mark this length on the new copper pipe section with a permanent marker. Use your pipe cutter to make a straight, square cut. Just as you did with the existing pipes, thoroughly deburr and clean both ends of this new replacement piece.
