There are many challenges faced during home repair and one that can be difficult is removing a stuck faucet cartridge or handle. When repairing a leaking faucet, the handle and cartridge are removed. However, sediment buildup creates a tight seal that makes the parts stick in place. There is a tool made just to get stuck cartridges out of faucets; use it, and the task is much easier. Plan on an hour or more to complete this project.

Unscrew the handle set screw, which is at the base of the handle or on top of it under a small, round cover which is easily removed by hand. An Allen wrench or screwdriver removes these screws. Take the screw out of the handle to ensure it is not preventing removal of the handle.
Pull the handle off. If this part sticks, attach a handle puller tool to the faucet and gently rotate the end to pull the handle off gradually. This tool also helps remove handle screws which are stuck. Attach both arms to the edge of the handle, insert the post into the screw head and turn the handle puller to remove the handle.

You may also grip the end of the cartridge with pliers, turn the cartridge back and forth and then pull the cartridge out.
Replace the valve stem and tighten with a bath socket wrench. Or, replace the cartridge and retaining nut. Slide the handle back on and tighten the handle screw with an Allen wrench or screwdriver.
