Things to Consider to Buy a Garbage Disposal Unit

Horsepower:

Depending on the amount of food you eat during a normal meal, the size of your sink, and the type of food you eat, you will need a model with a certain amount of power behind it. Horsepower helps to define the potential of a motor, but it does not completely determine whether or not it will work better than another model. Generally speaking, a ½ HP motor will do the job in most kitchens. However, if you have either a particularly large sink or deal with lots of bone matter in your cooking, you may need a ¾ HP or 1 HP motor to do the job. Otherwise, you risk having issues with the longevity of your garbage disposal.

Common HP of Garbage Disposal Motors:

½ HP
¾ HP
1 HP

Technology:

More than any other aspect, the best garbage disposal models are separated by the unique technologies they implement in their design. From tech that keeps your device from jamming to tech that ensures your system runs quietly, each feature is important to consider before making a final investment. Different models will focus on different benefits, and the differences between compact and large-sized disposal will differ the most.

Common Tech Features:
Drain Tech
Sound Proof Tech
Anti-Jamming Tech
Backup Reversal Tech

Installation:

Many users may become intimidated by the prospect of installing a garbage disposal in their homes by themselves. While it may be easy in reality to install a garbage disposal, there are many potential installation features to consider before making an investment. From whether or not a power cord is included, to how many parts are involved, each aspect will require a different approach to installation.

Many brands offer in-home services and warranties. If you doubt your ability to install a garbage disposal yourself, you should ensure you choose a company that offers this valuable perk.

  • Turn off power
  • Disconnect pipe from disposal unit
  • If your machine is screw mounted, you can remove any attached screws and then twist the whole unit off.
  • If your disposal is not screw mounted, just remove any holding screws and pull it out from the sink.
  • Put the new unit in its place and mount, either by a screw system or mounting screws
  • Re-attach pipe to the new unit
  • Plug in the new unit
  • Turn power back on

Additional Considerations:

How Do Garbage Disposals Work?

Even though these machines are in most households, many people have no idea how they work. Fortunately, the system is very simple, meaning that it requires little to no maintenance and is not hard to operate. The basic mechanics of a garbage disposal are that a motor spins an impeller, which grinds up food particles and materials to send it in to your drain pipe. You have to run water while the motor is working, to help keep everything lubricated and help the impellers work more efficiently.

Other than the impeller, the motor, and the drainage pipe, there is not much else involved in a garbage disposal. The only downside to this machine is that if something does break, like the motor, you usually have to replace the whole unit, since it will actually be cheaper that way.

Types of Garbage Disposals

There are two main types of disposals you can have:

● Continuous Feed: this is the most popular model, and chances are it is what you have in your sink right now. These disposals can process food continuously without stopping. However, they can be a safety hazard if hard materials (like silverware) drop into the unit while it is running.

● Batch Feed: if you only process a little food at a time, a batch feed unit may be for you. To operate this model, you have to fill the disposal, close the lid, and then turn it on. This model is a bit safer, but not recommended for large amounts of food waste.
