Step 4 · Extract the Old Cartridge

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.

Remove the old cartridge. A cartridge puller tool is highly recommended for this step, but pliers may also be used carefully to grip and pull the cartridge straight out of the valve body. Be mindful not to damage the valve body.
