Best Garbage Disposal Buying Tips and Choices

Garbage disposal

A quality garbage disposal can last as long as 15 years and shopping for a replacement can be overwhelming, especially with the numerous product changes over time. Most homeowners know of the two basic types of the best garbage disposal types – batch feed and continuous feed. Batch feed disposals grind the material in batches, while continuous feed disposals grind while the material is fed constantly into the disposer.

However, there are some technological differences that affect performance, functionality, and durability. Some of the best sink waste disposal brands available today include InSinkerator and the Badger 5. Garbage Disposal

Tips for Your Next Garbage Disposal Replacement

1. Type Of Motor

Disposals usually feature motors of two types – permanent magnet motors and induction motors.

Most disposals use induction motors, which are similar to the ones in large household appliances including furnaces, dryers, and washers. Induction motors produce less noise and offer a reliable and long motor life.

Permanent magnet motors are lightweight, variable speed motors similar to motors found in smaller household appliances including hair dryers, blenders, and power tools. Permanent magnet motors usually run at higher speeds, but they usually run fastest with smaller grind loads.

2. Grind Stages

Garbage disposals usually offer 1, 2, or 3 grind stages. The following are the differences between the three types and what they are used for:

1- Stage: These disposers feature only one stage of grinding. Food material is only ground once before it passes through the drain pipes with water.

2-Stage: These disposers grind food material in 2 stages to ensure a finer grind. The second stage of grinding helps to liquify food material allowing for more varieties of difficult food materials to be ground.

3- Stage: These disposers offer the finest grind possible thus allowing for the grinding of nearly any type of food material including hard or fibrous materials without worry of jams or clogs. 3-stage grinders are capable of handling even cut grains of cooked rice and rib bones.

3. Motor Horsepower

The motors in a garbage disposal can range from 1/3 horsepower to over 1 horsepower. The higher power disposers are usually capable of grinding heavier loads with ease. This helps to prolong motor life. If you plan to do frequent cooking or if you have a large family, consider going for a higher horsepower disposer. These also tend to last longer as they have the power to grind through material easier.

4. Component Materials

For the grind components and the grind chamber, there are 3 types of materials commonly used: galvanized steel, stainless steel, and plastic. Most grinders feature thermoplastic polymer grind chambers to help in resisting corrosion and rust. Galvanized steel is quite durable but it can corrode or rust over time. Stainless steel on the other hand helps to prolong disposer life due to its superior resistance to corrosion.

5. Noise Levels

Most homeowners are probably used to loud disposal noises. However, units with advanced sound technology can cut noise levels by as much as 30 to 60%. Look for disposers with sound insulation and include noise reduction features including anti-vibration tail pipes, anti-vibration sink mounts, as well as noise reducing sink baffles.

Using any of these insulation and noise reduction features will really help to lessen the grinding noise!

Dos and Don’ts: Garbage Disposal Operation

Once you have chosen your garbage disposer, it is important to know how to care for it properly to ensure that it serves you for the manufacturer stipulated period at least. Here is a list of dos and don’ts when it comes to operating your garbage disposer.


– Run the garbage disposer every time you put food material in it to prevent corrosion from food acid.

– Remove silverware along with other items from your sink before you power on the disposal.

– Use deodorizer, disposal cleaner, or citrus peel to help in freshening up the disposal and get rid of any lingering odors.

– Grind small sized bones to help scour the grinding chamber.

– Run cold water prior to, during, and immediately after operation.


– Put fibrous materials such as corn husks or celery into a standard disposal that handles normal amounts of food material including vegetable and fruit peels, small bones, and soft food scraps. The premium disposals can handle larger jobs.

– Reach into the disposer during operation.

– Grind shellfish or tobacco products if you have a septic tank.

– Run hot water while the disposer is in operation.
