Step 4 · Remove Old 3-Handle Valve Body

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

With the valve exposed, identify the hot water pipe, cold water pipe, and the shower riser pipe leading up to the shower head. Using a compact tubing cutter, cut each of these three copper pipes, leaving several inches of pipe extending from the wall fittings to work with. If the old valve is secured to a wood block, unscrew it. Once the pipes are cut and any mounting screws are removed, the entire 3-handle valve assembly can be pulled out of the wall cavity.
