How to Remove a Moen Shower Knob
- 1). Look over the surface area of the shower knob or handle to locate the screw. If you can't see one, look for a piece that has seams. This is a decorative cover over the screw.
- 2). Set the tip of a flathead screwdriver in the seam of the cover and pry it off the knob or handle. You should be able to see the screw holding the knob or handle in place.
- 3). Undo the screw using a Phillips or flathead screwdriver until you can pull the screw out with your fingers. Some screws may require the use of an Allen wrench.
- 4). Pull the handle or knob away from the shower plumbing as soon as the screw comes free.
