How to Choose InSinkErator Disposal: You Should Know Before Buying

To pick the most suitable disposal for your kitchen, you must pay attention to several aspects before purchasing. First, the quantity of waste will be relatively high, especially if you have a large family. In this case, you will need powerful disposal. In addition, several other aspects you need to consider that we shared below.


Different powered disposal sizes are quite different. Especially if you notice, you can see that the powerful disposal’s motor is relatively large, due to which its body size is also a little bigger.

For example, 1/3 HP disposals are 6 to 7 inches in range; on the other hand, 1 HP disposals are double size compared to 1/3 HP, i.e., 13 inches in diameter.

So if your kitchen’s under is relatively large, then the disposal size will not be an issue. But if there is limited space under the kitchen, you must pay special attention to the disposal size before purchasing.

Grinding Chamber Material

The grinding chamber of any garbage disposal is a significant spot; mainly, the operation is operated in this space. Most of the time, water also stocks. So when you are investing a higher price in a garbage disposal, this chamber is very important to be strong. In the market, you can see the section of different materials at different price ranges, which we discussed below briefly.

i. Plastic

Plastic grind chambers are generally protected from corrosion and rust, so if you want to get rid of all these aspects, this is definitely a great option. But if you think about higher strength, then there are chances of cracking. On the other hand, modern plastic chamber disposal is very durable so you can manage them easily for a few years.

ii. Stainless steel

Stainless steel grinder chamber disposals are relatively high strength and resistant. Besides, these are durable bodies compared to standard garbage disposals, so you don’t have to consider replacing them for a long time. You will be happy to know that most of the InSinkErator garbage disposal comes with a stainless steel grinding chamber. However, these disposals are relatively more expensive than other disposals.

iii. Pot Metal

These types of grind chambers usually look painted or plated. But at some point, this coating will chip away, and the underside will rust, which will look very poor. However, despite looking bad, pot metal’s durability makes it last for decades.


The loud noise of garbage disposal is very annoying. Mostly you can hear this noise during grinding, which is the most significant disadvantage of any disposal. But manufacturers pay special attention to this aspect during the construction of modern garbage disposals, due to which modern disposals include quiet technology; they are reticent. So if you don’t like extra noise, pay special attention to quiet technology.

Anti Jamming

This feature is handy, mainly sometimes when you put too much waste inside the disposal, which jams the blade. As a result, the garbage disposal automatic safety system turns off the garbage disposal. That’s why you need to manually remove the food waste and reset the garbage disposal to activate the disposal again.

But those who have this anti-jamming feature system at their disposal do not have to face this problem. This is because its blade starts reversing automatically when the anti-jamming garbage disposal gets jammed due to leftover food waste going inside. Therefore, it does not have to repeatedly face reset or disposal jammed issues.

Easy Installation

If you hire a plumber for a new garbage disposal installation, they charge up to $100 in many cases at an hourly rate. However, it is not so costly to replace the garbage disposal. If you have a basic knowledge of plumbing tools, then definitely try to install the garbage disposal yourself. In this case, buy a disposer with easy installation features, so you can easily install it by looking at the user manual.
