Our Top 5 Choices For The Best 3/4 HP Garbage Disposals

Here is a carefully selected list of our choices for the best 3/4 HP Garbage Disposals:

Below, we will give you an in-depth look at each of the units listed above to allow you to see precisely why we chose these to share with you.

How Powerful Is A 3/4 HP Garbage Disposal?

When it comes to a garbage disposal’s HP, it lets you know how much waste it can handle, as well as whether or not it grinds your food waste well. The weakest garbage disposals are 1/3 HP and are appropriate for those with one or two people in the family.

The 3/4 HP garbage disposals have a strong motor and great technology, so they can better handle hard vegetables and even chicken bones. This strength of disposal runs a lesser risk for clogs and jams. Also, it can serve a family of up to six people!

Features Of A 3/4 HP Garbage Disposal

This strength of 3/4 HP garbage disposal gives you real power. It can grind pretty much any food that you throw in there without causing any issues. The higher the horsepower, the stronger the components. Not to mention, stronger disposals last longer.

Moreover, most ¾ HP disposals have great sound-dampening features to reduce the noise throughout your home. The lower strength disposals can be extremely loud, which is very inconvenient if you’re a midnight snacker, and you need to use the disposal to throw out your scraps.

¾ HP garbage disposals are known to:

  • Jam less
  • Have less risk of clogs
  • Grind chicken bones
  • Operate quietly

Maybe you have children in the home or maybe you’re worried about destroying your disposal with cutlery that has fallen into the grinding chamber. That’s where the InSinkErator with Cover Control Plus comes in.

What sets this apart from the others is the safety feature that comes with it. If you have young children in the house, or anyone else who is prone to accidents (I know I am!), this is the perfect disposal for you.

With this model comes a magnetic safety cover. To activate the garbage disposal, you need to push the stopper into the drain and turn it until it locks into place. If the cover is not in place, the garbage disposal won’t turn on.

4. InSinkErator 3/4 HP Garbage Disposal

Number four on our list is the InSink Erator that comes with an air switch. Although, if you prefer, you can still hook it up to your wall switch instead. This disposal is also quiet and contains easy swap installation, so if you have an older InSinkErator model, you can install this quicker.

Air Switch

An air switch allows you to active your disposal with air pressure rather than electricity. This will reduce the risk of electrical shock because, as everyone knows, water and electricity don’t mix.

In addition, the button installs into the top of your counter, so instead of having to reach or walk across the room, you have the convenience of hitting the switch to start your disposal.

However, the power behind the model doesn’t raise the noise level. So, you get all of this power with less noise. Nobody wants an obnoxiously loud garbage disposal; this one is nearly whisper-quiet, allowing you to chop up food without disturbing the peace.

Easy Swap Installation

Installation is easier if you already have an InkSinkErator model that you want to change out. The Quick-Lock mount is compatible with all of the InkSinkErator models.

However, this garbage disposal includes a Quick-Lock mount, so if you don’t already have one, you can take the time to install it now. That way, when you’re ready for a new disposal, or an upgrade, you already have it in place for next time.

What You Need To Know To Choose The Best Disposal

The installation and use of waste disposals are regulated by some municipalities or localities. Towns without public wastewater treatment plants, where homeowners have their own “septic systems,” may not allow disposal use in particular instances.

Some types, however, are built expressly for use with septic systems. To ensure that all trash entering their treatment system is pulverized into small enough particles to be treated efficiently, some cities may require disposal units in kitchen sinks. In any event, before purchasing and installing a disposal, make sure to verify your local ordinances.

Disposals Can Be Stinky

A standard disposal can handle everything from fresh supper scraps to unidentified leftovers that have been hiding in the back of the fridge for weeks without being discovered. It should come as no surprise if you occasionally notice a persistent, foul odor coming from the sink drain.

There are a number of treatments for this problem, but we’ve found that mixing equal parts baking soda and distilled vinegar is the most effective.

Take about half a cup of baking soda and dump it into the disposal while the water and disposal are turned off. Then, over top of that, add about a half cup of vinegar.

Allow the mixture to sit for about five minutes before turning on the water, then the disposal for a few seconds before turning everything off as usual.

Difference Between Continuous vs. Batch Feed Disposals

As the name implies, continuous feed disposals can accept food waste that has passed through the drain and into the grinding chamber on a constant basis.

A remote switch is all that controls their operation. Only with the drain cover in place will batch-feed disposals work. You can’t put more waste in the disposal until the drain cover is removed and the disposal is turned off.

While these are inconvenient and time-consuming, the safety benefits of not being able to reach in while the disposal is running are obvious.

Gauging Sound Levels

Disposals’ attraction is influenced by how loud (or not) they are. If you’re grinding up leftovers from a huge meal, having one spinning on and off for an extended period of time can be inconvenient.

So, while disposing of half ears of raw corn, we recorded the sound levels of the first four models (which we examined in our most recent round of testing; the other three are holdovers, for which we only got peak sound levels) over time.

Considerations About Noise

Garbage disposals cause grinding noise and vibration, which are two of the most common complaints. A strong rubber gasket or union connects the appliances to the sink, which helps to decrease vibration. Sound-deadening insulation may be encased in a cover on more expensive devices.

Electrical Connections

New disposals may come pre-wired with a power cable and a plug, with a cord and a plug that must be wired yourself, or with no cord at all—the latter two being alternatives for replacing an older, hardwired device.

The disposal will need to be controlled by a remote switch that is within reach of the sink. If you’re installing a disposal where one wasn’t previously installed, you’ll need to power both the switch and the disposal’s plug outlet in the sink cabinet.

About Horsepower

1/4-, 1/2-, 3/4-, and 1-horsepower motors are commonly used in disposals. More horsepower usually means more powerful grinding.

Some manufacturers recommend a power level based on the number of persons in the household and the amount of activity the disposal will see.

Smaller families (one to three people) with rare disposal usage should choose something in the lower price range, while bigger families with regular disposal use should choose something in the higher price range.

Regardless of family size, the number is important to remember because higher-horsepower disposals have stronger components and may last longer.

Best Way To Maintain Your Garbage Disposal

Maintenance of your garbage disposal generally starts with using it correctly. Usually, you don’t have to provide genuine care to the unit as long as you’re following the manufacturer’s guidelines. With that said, here are a few things that you can do to ensure your garbage disposal is running the way that it should, at all times.

Always Check The Chamber

Before you run it, it’s always a good idea to take a spoon and stir around to feel for any cutlery that may have dropped into the blade chamber. This is especially important if you have little kids running around or if you just did a load of dishes on that side of the sink.

Making sure there’s nothing there before running the unit will help avoid any costly repairs due to an accidental break.

Don’t Grind Steak Bones

While chicken bones can usually be ground with a 3/4 HP disposal, you cannot throw in a beef-bone. This is because chicken bones are generally softer and more fragile. Therefore they’re easily ground by the blades of your disposal.

This is the same reason why dogs can chew beef bones, but not chicken bones. The chicken bones easily splinter, whereas the steak bones do not. A steak bone would most definitely destroy your disposal.

Clean Your Blade Chamber

If you use your garbage disposal every day, all day, you should take the time to clean out the blade chamber at least once a month. You can do this by using a good garbage disposal cleaner and running hot water to melt any residual grease stuck on the blades.

The more build-up you have on your blades, the less efficient they will be at breaking any food up. So make sure you take the time to clean it. However, if you find yourself using your disposal only once a week, then you could deep clean it once every 4 to 6 months.

Make Repairs Right Away

If you find that your disposal is leaking, take the time to repair it immediately. This will help it run more efficiently, and it will keep a small problem from turning into a larger one.

Related Questions

How many amps does a 3/4 HP garbage disposal use?

A 3/4 HP garbage disposal uses 13.8 amps. This is the full load current that the motor takes when operating. Keep this in mind when installing.

Does a garbage disposal need to be on its own breaker?

It is recommended to have a garbage disposal on its own breaker. However, a circuit shared with a dishwasher should be fine as well. Make sure that your garbage disposal is connected to an outlet that’s grounded or that it’s hardwired.

Do ice cubes sharpen garbage disposal blades?

Ice cubes are great for sharpening the blades of your garbage disposal. Additionally, they’ll break up grease build up as well. Throw a few cubes in and run it to sharpen the blades.

Wrapping It Up

We don’t need to explain why you deserve to have the best garbage disposal installed in your kitchen. Although, you should invest in one that can adequately meet your needs.

Make sure you know how much waste you dispose of so you can get the proper model to handle your food waste.

Each model has different features, so it’s also essential to look for a garbage disposal that’s user friendly to you and gives you the benefits you’re looking for. This way, you’ll purchase a unit that’s guaranteed to be the best according to your own standards.
