Step 3 · Remove Old Sillcock from Exterior Wall
Move to the exterior of the house. Locate the mounting screws that hold the spigot's flange to the wall. Use a drill or screwdriver to remove these screws. Once the screws are out, the old sillcock should be free. Firmly grip the spigot and pull it straight out of the wall. You may need to wiggle it slightly to get it through the opening.
