Step 3 · Remove the Old Spout
First, use a utility knife to carefully cut any caulk or sealant between the spout and the tub surround. For a SLIP-ON spout: Use the appropriate size hex key (Allen wrench) to turn the set screw on the underside counter-clockwise. You only need to loosen it a few turns; do not remove it completely. Once loose, grasp the spout firmly and pull it straight off the copper pipe. You may need to wiggle it slightly. For a THREAD-ON spout: Grasp the spout firmly with both hands and turn it counter-clockwise. If it's too tight, you can insert the handles of a pair of pliers or the handle of a wrench into the spout's opening for leverage. For very stubborn spouts, wrap the spout with a rag and use a pipe wrench to turn it counter-clockwise.
