The following instructions assume the handle and associated handle pieces have been removed.

Cartridge Nut and Cartridge Removal: The Cartridge Nut can be removed using either a Moen Removal Tool 14272 or Needle Nose Pliers

This image illustrates the location and the points of contact that the tool will need to make. The nut is threaded so the tool will need to be rotated counter clockwise to remove it.
