Step 3 · Remove the Garbage Disposal Unit
Garbage disposals are heavy. Support the unit from below with one hand or prop it up on a stack of books or a block of wood. Locate the mounting ring at the very top of the disposal where it connects to the sink flange. Insert the tip of your disposal wrench (or a large flathead screwdriver) into one of the lugs on the lower mounting ring. Turn the ring counter-clockwise about a quarter-turn until it disengages from the ramps on the upper mounting ring. The disposal will drop slightly. Carefully lower the heavy unit and remove it from the cabinet.
