Prior to testing the garbage disposal for leaks, unplug it at the wall outlet and turn off the power from the breaker box to prevent electrical shock. Then insert a watertight sink stopper into your sink drain and wipe the unit dry with a clean cloth. In any handy container, mix a few drops of food coloring into a few cups of water, and pour the dyed water onto the sink stopper to help you locate the leak.
Lay the disposal on its side under the sink so you can make the electrical connections. Make sure the circuit breaker is off. Remove the plate on the bottom of the disposal to expose the wiring and use wire connectors to connect the wires from the disposal to the matching wires from the power supply. Finally, secure the power cord to the bottom of the disposal using the proper connection. Replace the plate to cover the wires. (See Fig 6)
