Take apart the faucet handle

To get to the damaged washer and replace it, first you have to remove the faucet handle.

  • Unscrew the decorative cap on the handle using the multiple slip-joint pliers. On some models, the cap is just a red or blue disk (indicating hot or cold) that can be pried off.
  • Remove the handle screw.
  • Pull off the handle.
