My experience is, first remove the U-shaped pin behind the front of the brass casing by pulling it up. It is very hard to see because the pin sets behind the front of the brass casing, the top of the pin sets flush with the casing, and the pin is back in the wall where it is dark and cramped. Once the pin is out, place the plastic remover tool over the front of the cartridge and use a wrench to rotate the cartridge clockwise and counterclockwise a few degrees (until the edge of the casing stops the turning). Turn several times to break the seal between the outside of the old cartridge and the casing wall. Insert the screw which holds the handle onto the cartridge, grab the head of the screw with a pair of pliers and pull straight out. If the cartridge does not come out, go to home depot and buy a cartridge remover tool and use it. This tool only lets you pull out the cartridge a quarter of an inch. If you can't pull the cartridge by hand with the tool attached after the cartridge moves a quarter of an inch, get a 4-foot long 2x4 and a few wood shims. Stack the shims on the tile beside the cartridge and use them as a pivot point for the 2x4. Put one end of the 2x4 under the removal tool and pry backwards, keeping the cartridge as straight as possible. If this fails, try prayer. If successful, be sure and put the provided lubricating jell on the new cartridge before inserting it.
