Once loosened, pull the cartridge straight up to remove.

  • With the cartridge free of all clips and fasteners, it can be removed. Except of course it’s not always that simple because minerals in the water can make your cartridge stick and be a little difficult to remove by hand. That’s why your new cartridge kit usually comes with a white plastic tool with a square top. It will be used to loosen the cartridge.
  • Place the tool on top of the cartridge stem and line up the notches in the plastic tool with the tabs on the cartridge so it fits squarely on top of the cartridge.
  • Using a adjustable wrench or pliers, grab the square top of the plastic tool and twist the cartridge back and forth in its housing to loosen the cartridge.
  • Remove the plastic tool and using a pair of pliers, firmly grasp the top of the cartridge stem and pull straight up to lift the cartridge out of its housing. Some water will come out with the cartridge, that’s normal.
  • If the cartridge is stuck and you cannot remove it, you will have to use a cartridge puller.
