Disconnect the Garbage Disposal
Unplug the garbage disposal from the wall outlet.
Place a bucket or other container under the drain trap to catch the water that drains from the pipes. Use pliers to loosen the slip nut at each end of the trap bend. Unthread the nuts and pull the trap straight down to remove it.
Loosen the slip nuts and remove the continuous waste pipe and the tee that connects to the discharge pipe of the disposal.
