From simplifying the way you dispose food scraps to making your kitchen a little more earth-friendly, a garbage disposal is an obvious choices for most kitchens. A garbage disposal adds value to your home. Finding the right fit for your kitchen and lifestyle can make your kitchen cleanup a whole lot easier, and today we’re going to explore the ins and outs of garbage disposal selection, with a few reviews of my favorite units. Specifically, we’re going to look at the Best 3/4 HP Garbage Disposal and help you to select one for your kitchen. A 3/4 HP Garbage Disposal is a powerful unit that tidies up your kitchen of food scrap waste in no time at all.

If you have a larger family or are an avid home cook, you definitely want to consider a 3/4 HP garbage disposal for your home. While there are cheaper models out there, anything less than 3/4 HP in power may not be able to withstand the rigors of the busy kitchen.

How to Choose The Right 3/4 HP Garbage Disposal

Choosing your garbage disposal doesn’t need to be a chore! There are some tips and tricks to remember about garbage disposal use and selection that will help you to make the right choice for your home.

How a Garbage Disposal Works

Garbage disposals are relatively straightforward appliances to understand and operate. They work with a system of aligned blades and impellers to pull food in through the top and process it in a specialized grind chamber.

There are two types of garbage disposals available:

Continuous Feed

works by pulling food scraps and water in through the top and grinding until power is manually turned off (by flipping a switch)

Batch Feed

A less common style that involves loading food scraps into the grind chamber, closing the top, and operating the system to digest food as a batch.

Best Continuous feed garbage disposals are much more popular in the United States because installation and operation are incredibly straightforward. All of the units we’re reviewing here are continuous feed models.

The amount of grind power that your garbage disposal offers is critical for knowing how it will operate and whether it will be effective in your kitchen. Garbage disposals come in multiple sizes, ranging from 1/4 HP to 1 HP - and larger for commercial settings.

Lower powered units are ideal for apartments and small families, but do not perform well in a heavily used kitchen. A 3/4 HP garbage disposal is going to give you the power that you need to work through the food waste generated by a family that cooks and eats at home frequently.

Here we’ll address some of the best 3/4 HP garbage disposals for your review. If you know you need this power level, then you’ll be impressed by the options available for your home.

How to Use a Garbage Disposal

Garbage disposals don’t take much time to learn and their operation is as easy as the flip of a switch. Since we’re focusing here on continuous feed garbage disposals, we’ll limit the scope of our conversation to how they work specifically.

Continuous feed units install directly into the kitchen sink’s drain and are plumbed into the home’s outgoing sewage line. All you have to do is load food scraps into the system by scraping plates or emptying too-old takeout containers into the sink and pushing the scraps into the drain. From there, the garbage disposal will grind up your food scraps into minuscule bits and send them away.

Obviously, there are some things that even the best garbage disposal cannot power through and you’ll want to avoid putting them into your unit. They include:

  • Potato and onion skins
  • Chicken bones
  • Coffee grounds
  • Pasta

How Much do You Plan to Spend?

Since you know you want a higher powered unit in the 3/4 HP category, your investment is going to be higher than if you were choosing from a selection of smaller machines. However, this does not mean that you’re going to spend a small fortune on your garbage disposal.

Garbage disposals add value to your kitchen and simplify a fairly gross chore you handle daily. Allocating a portion of your kitchen remodel or building budget to this appliance is a worthwhile designation that will save you plenty of headaches over the years.

That being said, there is still a range of price tags associated with 3/4 HP machines, so you can plan your investment accordingly. Even with a smaller budget, you can get your hands on something that will get the job done, and do it well.

Other Considerations

There are, of course, some other factors to consider before you set your sights on one garbage disposal in particular. In fact, before you even make the decision to purchase a garbage disposal, you’ll want to ensure that your home and location is suited to having one.

Research the answers to the below questions before adding a disposal to your renovation list:

​Does your home have a septic system?

If your home has a septic system, you must take special care to choose a garbage disposal that is compatible with your system.Most modern garbage disposals are septic safe, but you do want to do your research ahead of time. Even if the unit that you want is not rated for septic safety, you can purchase tablets to treat your septic system with to help it break down your food waste.

​Are there local ordinances prohibiting garbage disposals in your area?

Believe it or not, there are some towns and municipalities that disallow garbage disposal installation and use within their borders.Often these rules are in place to protect an older sewer or water treatment system from overuse. While there aren’t too many places that still forbid garbage disposals, it’s always better to be safe than sorry, so check to see that your town is in the clear.
