In the United States, most homeowners have a garbage disposal in the kitchen. As such a popular appliance, it’s easy to take the lowly garbage disposal for granted. Garbage disposals are wonderful appliances.
They allow us to scrape food down the drain while doing dishes without worrying about clogs. They also reduce the amount of waste we have to haul out to our trash can each week. But you know what they say: out of sight, out of mind.
If you’re not careful, your garbage disposal might be hiding more than just the food you want to be rid of. If you’re not using and caring for your disposal properly, it could be hiding unsightly clogs that could lead to expensive plumbing bills. As those clogs sit and fester in your disposal, they could also be hiding colonies of stinky bacteria.
How Long Does a Garbage Disposal Last?
The life span of your garbage disposal is highly dependent upon how well you care for it. With proper use and maintenance, the average disposal lasts 12 years. If you’re really intentional about caring for your unit, it can last up to 15 years or more.
To help your disposal last longer, avoid putting the following items into your disposal:
- Coffee grounds - Although some may claim that coffee grounds can deodorize a disposal, they’re more likely to solidify in your drain and cause clogs.
- Thin, membranous materials like onion skins, egg shells, or potato skins - These are too small to be effectively ground up by the disposal, so instead, they’ll stick to the unit and collect other debris.
- Fibrous vegetables like pumpkin, celery, or corn husks - Anything that’s long and stringy will be difficult to grind and will instead wrap itself around your disposal blades.
- Bones, fruit pits, seafood shells - Some newer disposals are capable of handling really solid materials, but if you aren’t positive that your machine can handle them it’s best to just throw them in the trash.
- Grease - Always dispose of grease in the trash or you’ll end up with a huge issue in your drains.
- Harsh chemicals or non-edible materials - Chemicals can cause corrosion and shorten the life of your machine, and trash should just go in the trash.
Be sure to run your disposal regularly, even if you don’t have anything to put in it. This keeps the parts loose and limber. You also want to make sure that you’re not overworking your disposal. Grinding a lot of large pieces of food, pasta, and bones will shorten the life of your disposal.
What Ingredients Do Disposals Love to Eat?
Believe it or not, your disposal does LOVE to eat as long as you give it a cold drink of water to help the food down. While you don’t want to ever pour grease into your disposal, it’s likely that some of the butter from your potato will make it down the drain from time to time.
Cold water solidifies fats so they can be ground up and run down the drain without clogging. Disposals like to eat citrus peels to stay fresh and deodorized, as well as ice cubes to stay clear of debris. If you really want to feed your disposal well, consider freezing vinegar cubes. This will help clean off the blades while also disinfecting them.
Your disposal has a light appetite, so stick to feeding it scraps rather than full meals to keep it healthy. They like to eat like a baby so anything you wouldn’t give to little Timmy should go in the trash rather than the disposal. Cooked meat, fruit, non-fibrous vegetable scraps, and other soft, biodegradable foods are ideal for your disposal.
Which Garbage Disposal is the Quietest?
The Insinkerator brand disposals are well-loved in American kitchens and have been for decades. The Insinkerator Evolution Excel emits just 45 decibels (approximately the volume of a bird call) when it’s running and is consistently rated as the quietest disposal currently available.
It features Insinkerator’s SoundSeal technology for “noise free” operation. Unfortunately, it also comes with a hefty price tag of about $350. Other considerations when choosing a disposal are power and size. Smaller disposals with 1/2 horsepower or less are often available for under $100, but they’re more prone to clogs.
Disposals with 3/4 or 1 horsepower often have insulation to reduce sound and are less likely to clog, but they’re larger. Before purchasing a disposal, make sure you have enough room under your sink to accommodate the appliance.
Treat Your Disposal Right, and It’ll Treat You Right Too
The garbage disposal is an important feature in a lot of kitchens, and sometimes you don’t realize how valuable it is until it stops working. Feed your disposal right and run it regularly to keep it working for a decade or more, this way you won't be suffering any plumbing emergencies.
