Step 4 · Disconnect and Remove Old Valve

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 access to the valve, you can now remove it. The valve body is likely soldered to three copper pipes: hot inlet, cold inlet, and the shower riser outlet. Use a tubing cutter to make clean cuts on all three pipes, leaving a few inches of pipe extending from the valve. Have a small bucket and rags ready to catch any residual water. Once the pipes are cut, the valve may also be screwed to a wooden support beam (a stringer) between the studs. Unscrew the valve from this support and remove it from the wall.
