If your garbage disposal has seen better days, replacing it can bring a fresh start to your kitchen. A functional disposal not only helps keep your kitchen clean but also prevents clogs and odors. However, you might be wondering about the costs and steps involved in this DIY project.
Typically, a new garbage disposal can range from $70 to $300, depending on the brand and features. While you can hire a professional for installation, tackling this task yourself can save you some cash and give you a sense of accomplishment. With the right tools and a little guidance, you can have a new unit up and running in no time. Let’s dive into what you need to know to make this upgrade seamless and budget-friendly.
Reasons to Replace Garbage Disposal
Garbage disposals can deteriorate over time, leading to performance issues in your kitchen. Identifying key indicators can help you decide when to replace your unit.
Common Issues with Old Garbage Disposals
- Age of the Disposal: Garbage disposals typically last between 8 to 15 years, depending on usage and maintenance. If yours approaches or exceeds this age range, consider replacement.
- Frequent Clogs: Experiencing frequent clogs can point to malfunctioning motors or worn-out blades. If your disposal frequently jams, replacing it is advisable.
- Persistent Odors: Ongoing bad odors, despite regular cleaning, often signify trapped food particles or deeper issues. These odors may suggest that replacement is necessary for effective sanitation.
- Leaks: If leaks originate from the disposal itself rather than connectors or tubes, this signals a need for replacement. Over time, pipes can crack, and seals deteriorate, compromising functionality.
- Improved Performance: New garbage disposals often operate more efficiently, reducing the likelihood of clogs and malfunctions.
- Enhanced Hygiene: Modern units typically feature improved designs that prevent odors and trap food particles better, contributing to a cleaner kitchen environment.
- Energy Efficiency: Newer models often use less energy, leading to lower electricity bills and a smaller carbon footprint.
- Noise Reduction: Upgrading to newer models can provide quieter operation, enhancing your kitchen experience without disruptive noise.
- User-Friendly Features: Many modern disposals come with features such as better grinding power and improved safety mechanisms, making them easier to use and maintain.
Choosing the Right Garbage Disposal

Selecting the right garbage disposal is essential for optimal kitchen functionality. Focus on key factors like type, features, and performance to make an informed decision.
Types of Garbage Disposals
- Continuous Feed Disposals: Most common, these units allow you to add food waste while operating. They offer convenience but require regular maintenance to prevent clogs and odors.
- Batch Feed Disposals: These models require waste to be added in batches. They promote safety, as activation only occurs when the cover is in place, reducing the risk of accidents.
- Motor Power: Measure power in horsepower (HP). Standard options range from 1/3 to 1 HP. Higher HP results in better grinding capabilities for tougher waste.
- Noise Level: Some models include noise-reduction features. Assess decibel ratings to determine the ideal choice for quieter operation.
- Durability: Look for high-quality materials. Stainless steel components generally offer improved resistance against corrosion and wear.
- Installation Type: Check compatibility with your plumbing. Most disposals fit standard sink drains, but certain models may require additional adjustments.
- Ease of Cleaning: Some disposals come with removable components for easy cleaning. This feature helps maintain hygiene and prolongs the unit's lifespan.
- Warranty and Support: Review warranty periods offered by different brands. A longer warranty often indicates manufacturer confidence in their product's durability.

Maintenance Tips for Your New Garbage Disposal

Maintaining your new garbage disposal ensures optimal performance and longevity. Regular upkeep prevents clogs and unpleasant odors, allowing your kitchen to function efficiently.
Regular Cleaning Methods
- Use Cold Water: Run cold water while the disposal operates. Cold water solidifies grease, allowing it to be chopped and drained easily.
- Clean with Ice: Toss a handful of ice cubes into the disposal weekly. The ice sharpens blades and helps dislodge debris stuck inside.
- Incorporate Baking Soda and Vinegar: Pour 1/2 cup of baking soda and 1/2 cup of vinegar into the disposal. Let it fizz for 10-15 minutes, then rinse with hot water to eliminate odors.
- Citrus Peels: Grind citrus peels to freshen the unit and provide a pleasant scent, while naturally cleaning surfaces.
- If It Hums But Doesn’t Work: This may indicate a jammed motor. Use a hex key to manually rotate the blades, dislodging any objects.
- If It Leaks: Check the connections for tightness. Tighten any loose screws or mounts. If leaks persist, replace the damaged seal.
- If It Emits Bad Odors: Regular cleaning should prevent odors. If they occur, clean the disposal with baking soda and vinegar.
- If It Stops Working: Check the reset button located on the bottom. Press it if the disposal trips. Ensure the power supply is functioning as expected.
With these maintenance tips, you can keep your garbage disposal running smoothly, contributing to a cleaner and more efficient kitchen environment.
