1. An extraction tool for removing a thermostatic cartridge from a valve assembly, the extraction tool comprising:
a cap comprising an opening in a top surface of the cap and a circular opening in a bottom portion of the cap, wherein the circular opening comprises a bottom rim configured to contact a manifold of the valve assembly when the extraction tool is in operation; and
a screw, wherein the cap is configured to receive the screw at the opening,
wherein, when the extraction tool is placed over a portion of a thermostatic cartridge installed in a valve assembly, an end of the screw is configured to screw into an opening of the thermostatic cartridge,
wherein, when the bottom rim of the cap comes in contact with the opening of the thermostatic cartridge, rotation of the screw exerts a force on the thermostatic cartridge that lifts the thermostatic cartridge from the valve assembly.
