Why do you Need a Garbage Disposal with a Dishwasher?


Imagine stepping into your sparkling clean kitchen after cooking up a storm, only to be greeted by dirty plates piled high in the sink. It’s enough to dampen any chef’s spirits! But fear not—there’s a game-changing solution that will transform your dishwashing woes forever: combining the power of a dishwasher with a garbage disposal.

By pairing up these two underappreciated appliances, you can bid farewell to tedious scraping and rinsing before loading dishes into the dishwasher. Say goodbye to stubborn food particles lingering in your sink drain or attracting pesky critters. Let us uncover exactly why investing in both of these kitchen lifesavers is an essential move for anyone looking to reclaim their time and sanity in the heart of their home—the kitchen!

The Role of Garbage Disposals in Dishwasher Functionality:

Dishwashers use a combination of hot water, detergent, and powerful jets to clean and sanitize your dirty dishes. As the dishwasher runs its cycle, it sprays water over the dishes while simultaneously agitating them with rotating blades or arms. This process helps remove food particles and stains from the surfaces of the dishes.

However, even with this advanced technology, dishwashers are not equipped to handle large food scraps or chunks of debris. That’s where garbage disposals come in. Garbage disposals are essential for maintaining the functionality of dishwashers by serving as a pre-treatment system for food waste.

When you scrape leftover food into the kitchen sink, it is crucial to have a garbage disposal to break down these food particles before they enter the dishwasher. The garbage disposal works by grinding up solid waste into smaller pieces, which can then be easily flushed away through the plumbing system.
