Get matched with top garbage collectors in Holdrege, NE

No, you don’t need a garbage disposal for a dishwasher. A dishwasher will work without a garbage disposal. However, the two appliances pair well and are often installed together. It is rare to see a home with a dishwasher that doesn’t have a garbage disposal, but that doesn’t mean it's not possible. Each appliance serves its own purpose. 

Many homeowners wonder if a garbage disposal is necessary with a dishwasher. After all, many dishwashers are powerful enough to handle bits of food with no issues.  

Still, your dishwasher should not act as a replacement for a disposal. Subjecting your dishwasher to continuous leftovers could lead to major clogs. If you don’t want a garbage disposal in your kitchen, simply scrape away any extra food into your trash can or compost pile.

The most common garbage disposal size in the U.S. is 1/2 horsepower. This size is ideal for households with three or fewer people or those that don't produce much food waste. Although 1/2 horsepower can't handle the typical food waste load for a household of four (which is about 250 pounds of food waste annually) as effectively as 3/4 horsepower, it remains the most common size of garbage disposal on the market.

Garbage disposals fit the drains of nearly every sink out there due to universal drain hole sizes of 3 1/2 to 4 inches, but the same isn’t true for the housing underneath the sink. You need plenty of room to fit a garbage disposal under there, so measure the space ahead of time and use those dimensions when shopping for a new model. If you’re replacing an existing model, get one in that size.
