Step 1. Unthread the white hex cartridge nut (#1).

Step 2. Lift the stem extension (#2) off of the faucet. See details.

  • Two Piece Stem Extension (#2)-This style is used in lever handles and will require needle-nose pliers to remove the lower portion of the stem extension.
  • Single Piece Stem Extension (#2)-This style is used in knob handles and does not require a tool for removal.


Reinstall the stem extension (#2).If you have a two piece extension, the lower stem extension will be installed before the upper stem extension. The upper stem extension has small teeth on the bottom that line up with the indents on the top of the lower stem extension. Rotate the stem extension to the "off" position (clockwise for hot, counter clockwise for cold) until it stops. Thread the cartridge nut (#1) back in.
