Factors to Consider Before Buying A 3/4 Garbage Disposal

Let’s be real; Almost every ¾ HP garbage disposal on the market is going to claim that they’re the best, right? However, many of those claims are unsubstantiated. So, you can’t just rely on the titles to tell you which one is the best for you.

Let’s take a look at what factors we should consider before buying.

Power and Capacity

No matter what you choose, you’re going to want a model that can handle your regular kitchen waste without any clogging or jamming. A 3/4 HP disposal provides the right amount of power to chop your food waste, decreasing the risk of clogs and jams. The amount of waste, as well as the type, is what you’ll use to determine what size of garbage disposal is best for you.

Noise and Vibration

It’s safe to say that most models do make less noise and cause fewer vibrations. However, that truth doesn’t hold for all of them. So, you need to look carefully at the features of each disposal so that you know for sure whether it’s quiet and doesn’t vibrate as severely as others do.

Garbage Disposal Size

Measure the area below your sink before purchasing your garbage disposal. This will help you to decide based on the size of garbage disposal your sink can hold.

Installation

Since it costs between $200 to $400 in labor fees to hire a professional, you’ll want a model that’s easy to install so that you can do this yourself and save hundreds of dollars. There are many models out there, including the ones in this guide that are easy to install.

Durability

When searching for a unit, you will certainly want a durable one. This type of disposal will last you longer than one that isn’t built with corrosion-resistant stainless steel blades. Finding one that is rust proof will make your garbage disposal last up to 8 years longer.

Grinding Stage

Efficient grinding is a must. Searching for a disposal with stage two grinding technology not only grinds your food waste more efficiently, but it also grinds it a lot quicker. Also, units with stage two grinding are typically better at disposing of the tougher food scraps such as melon rinds, carrots, and chicken bones.

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.

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

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.
