If the old spout has a setscrew on the bottom, loosen the screw, and pull it off the supply pipe. If it does not have a setscrew, insert a large screwdriver into the spout, and turn it counter-clockwise to unscrew it.
If the supply line from inside the pipe is 1/2-inch copper but has a threaded fitting on the end, cut it with a tubing cutter to leave three inches of pipe exposed. If it is galvanized pipe, purchase a threaded spout.
Use steel wool to clean the copper pipe to remove any corrosion. Make sure it is bright, and there are no remaining burrs or sharp edges.
Apply silicone lubricant on the end of the copper pipe. Slide the new spout in place, and tighten the setscrew. Check for leaks. If the supply line is galvanized, apply plumber's tape to the threads at the end of the pipe, and screw the new spout into place.
