Before you begin, gather the following tools:

3. Remove Handle

Use the hex key to loosen the set screw on the handle and pull the handle straight up to remove it.

Use a flathead screwdriver to pry off the cap on the top of the cartridge. Then, insert the hex key into the cartridge and turn it counterclockwise to loosen it. Pull the cartridge straight up to remove it.
