Flush with water. Simply flushing out the garbage disposal with water will help to remove any loose dirt or grime. Stopper the garbage disposal, add a squirt of dish soap and run the hot water until there is 2 to 4 inches (5.1 to 10.2 cm) sitting in the sink. Pull out the plug and turn on the garbage disposal, allowing the water to flush through.
Garbage disposal units have standard hook-ups that are present on all models from every manufacturer. They all have an inlet and an outlet and a dishwasher inlet on the side, and a disposal unit can leak in those areas. If the body of the unit is leaking, the unit must be replaced, but other leaks in a disposal unit can be repaired by a do-it-yourselfer who has basic skills.
As advertised, it does come with a corded plug so it will need an outlet. My old Badger was a direct wire. Some folks tore out the cord and the strain relief as a fix and hard wired it like their old one. Some folks put an outlet in, which I found that to be a 15 minute job. I didn't want to mess around with chopping out the stock cord and putting in a new one and messing with the strain relief replacement. I thought the new outlet process was much easier because, heck, the wire's already there and that's always the hardest part of wiring a box! I shoved some of the extra length of the existing wire back into the hole in the wall that it came out from. I thought carefully about where the new box should go so the body of the disposal didn't hit it. I screwed it to the back of the cabinet, poked the wires into the box, screwed them to a new receptacle and, voila!. NOTE: IF YOU DON'T KNOW WHAT YOU'RE DOING WITH ELECTRICAL WIRING, DO NOT ATTEMPT THIS YOURSELF. If you do, be sure to kill the power at the circuit breaker and it is probably the easiest box you will install. Just make sure it is securely mounted into something besides the flimsy back panel of the cabinet.
If your garbage disposal is making a clicking or rattling sound, there may be some food particles that will not grind up inside. Remove power from disposer, reach into the sink hole with a pair of tongs and remove anything that is still down in the disposer. Test your disposer to be sure the noise is gone. If not continue troubleshooting your disposer issue (see below).
