Choosing the Best Garbage Disposal

To find the best disposal you need to know about the basic features of a garbage disposal. When doing reviews, we focus mainly on those.

1. Capacity and Power

A good garbage disposal will process the regular kitchen waste without any hesitation. But the amount of waste or speed the grinding speed will depend on how powerful your device is. Basically, there are three types of motor power used in garbage disposals.

  • 1 HP
    This is the most powerful motor used in a garbage disposal. The disposals with 1 hp power motors are usually most powerful in terms of grinding operation and speed. These disposals are best for a big family with lots of grinding needs. The best 1 HP Garbage disposals available in the market are InSinkErator ExcelWaste King L-8000 Legend and Waste King A1SPC Knight.
  • ¾ HP  
    These disposals are best for medium usage. A family with 4 to 6 members can easily use these disposals for a regular basis. The most popular ¾ Hp disposals are InSinkErator Evolution CompactInSinkErator Evolution Essential and Waste King L-3300.
  • ½ HP  
    Best for single person or couple users who needs a lower amount of kitchen waste to dispose of than the big families. Usually these disposals cost the lowest and best for budget friendly purchase. InSinkErator Badger 5 garbage disposal is the most popular ½ garbage disposal of all time. But more recently the Waste King L 2600 is being very popular as one of the most low-priced garbage disposals.

2. Continuous Feed vs Batch Feed Garbage Disposal

A continuous feed garbage disposal continuously grinds waste from the moment you switch on the power button. On the other hand, the batch feed garbage disposals start working when a cover goes over the disposal entrance.

Usually the continuous feed disposals are more preferred by most of the consumers because it saves your time. You can just throw waste into the sink and it starts grinding. It is best for the more waste and a hassle free operation. On the other hand, batch feed garbage disposal is a safer option in terms of the cover prevents falling small cutleries inside the sink and finally break it. But if you have a lot of food waste then this will take more time and be less convenient in terms of operation.

3. Grinding stage

Your disposal must grind the wastage into finest particles to make sure it totally gets washed out through your pipeline and never cause a clog. The more grinding stages ensure more tiny leftovers that are great for not making any clog or jam through your pipeline. Waste King has a single stage grinding system for all of their disposals, even one the most powerful ones. On the other hand, InSinkErator garbage disposals contain a different number of grinding stages for their different range of disposals. The old Badger 1 garbage disposals used to contain one grinding stage. But now a days, the grinding stages differ from 1 to 3 stages. A 3 stage grinding chamber can convert your food waste into the smallest particles and you never get to worry about any jam through your sewage system.

4. Noise and Vibration

A good garbage disposal must make the least amount of noise and vibration. Most of the people complain about the motor noise and vibration cause while the grinder starts operating. If you have a sleeping baby, or a studio apartment or even an open kitchen; you would not like to get interrupted by the irritating sound or humming of your garbage disposal. Most of the garbage disposals I’ve recommended are made with sound proof materials nowadays to reduce the sound impact as much as possible. The mounting system and the rubber baffle make sure you feel the least vibration in your sink and close to zero sound interruption.

5. Mounting

InSinkErator’s Quick-Lock mounting system

InSinkErator has a quick-lock mounting system that is universal for most of their disposals. So if you are replacing an old badger disposal with a new InSinkerator Evolution Series, you will easily be able to replace it and mount it within minutes. The quick-lock mounting system is made of stainless steel and easily replaceable with any existing disposal mounting.

Waste King’s EZ vs 3 Bold Mounting

Installation directly depends on what mounting has been used by the manufacturer. For example, Waste King has two type of mounting system for their disposals. One is 3 bolt mounting system and another is EZ mounting system. In 3 bolt mounting all are stainless steel mounting components and it does not contain the removable splash guard above the stainless steel sink flange. On the EZ mount system, you get a removable splash guard and the system has plastic and aluminum mounting components. Many prefer the EZ mounting because of its removable splash guard which is easy to clean and many other prefer the 3 bolt because all the components are made of stainless steel that ensures more durability. Other than the mountings there are no differences among these two systems.

6. Durability

Your garbage disposal must be durable for a long time. To find a more durable garbage disposal you need to find these features in it.

Corrosion or Rust Proof Grinding Chamber & Components

You need to make sure the disposal you are going to purchase must have Stainless Steel grinding chamber and grinding components. The stainless steel rust and corrosion proof and makes your garbage disposal more durable.

Jam sensor & Automatic Reverse grinding technology

Anti-jam Sensor and an automatic reverse spinning technology both are best for preventing the jam inside your grinding chamber. Not all the garbage disposals are available with these features. Only Insinkerator Evolution Series have the feature of Auto Reverse Grinding System.

7. Installation

A good garbage disposal must have a clear instruction manual and all the parts needed to complete the installation. People usually get anxious about installing or replacing a garbage disposal or think that they need to spend extra bucks to hire a plumber. But it’s not a hard task if you want to do it yourself. All you need is a good instruction and everything needed to complete the installation.

8. Size

Before going for the purchase, you must check the space under your sink and check the disposal dimension to make sure it is going to fit. Many garbage disposals I’ve recommended in my reviews are not very compact in size. So if you have little space under your sink and you want to have a big disposal like Evolution essential or Evolution septic Assist, then you must reconsider your option or try to increase the space under your kitchen sink.

9. Septic Tank Safe

If you are using a septic system the garbage disposal must be safe for your septic tank. Otherwise, it can ruin your whole septic system. So make sure you are going for the right option.

10. Warranty & Support

You should look for a longer period and In-Home service warranty. Besides that make sure the support and after sale service is good and the promises of warranty are authentic.

How much does a Garbage Disposal Cost?

There are different ranges of disposals depending on features and power. Usually the garbage disposal cost differs depending on motor capacity, special features and of course brand. InSinkerator, the inventor of garbage disposals is going to charge you premium where you can get waste king’s garbage disposals at a lower price.
