Here’s a funny mistake I almost made: wiring the disposal to the same switch as the garbage disposal air switch. Wait, no—the disposal itself needs a separate electrical circuit, often with a wall switch or an air switch on the counter. In a double sink, you also need to decide if the disposal basin’s drain has a separate stopper or a continuous drain grid. The diagram usually shows the disposal connected to a dishwasher drain as well—because why not add more pipes for fun?

Seriously, look at a typical diagram: the dishwasher hose runs into a knockout port on the disposal. That means both your sink and dishwasher share the same grinding doom. Romantic, isn’t it? Just remember to knock out the plug inside the disposal port before connecting the hose—or you’ll flood your kitchen with dish soap suds.
