Garbage Disposal Buyers' Guide
What is a Garbage Disposal Unit?
A garbage disposal is a small, under-sink, unit, designed to macerate kitchen waste into small enough particles that it won’t block up the civic sewer systems and water treatment plants.
Essentially, a garbage disposal just mashes up your food waste, and flushes the problem away, keeping your bins tidy, saving you money on bin liners, and keeping your kitchen effortlessly clean.
Is Garbage Disposal Good for the Environment?
It was previously thought that garbage disposal units and macerators were bad for the environment, leading the state of New York to ban them in the 1970s, it is now understood that that was more to do with civic management of waste than the actual environmental impact of it.
When your food waste goes into the trash, it ends up in the landfill. As food breaks down anaerobically in landfill, it produces methane, which is far worse for the environment than carbon.
By sending your food waste down the garbage disposal chute, you’re sending it to water management facilities that can properly cope with the waste.
However, wastewater sites in different states have different ways of dealing with food waste. Some states separate food waste, and sewage and simply put them back into landfill. In those states, your garbage disposal is doing more bad than good.
In other states, that state burns the food waste, releases carbon, and adds the ash to landfill. This is actually better than it sounds, as the carbon is less damaging than the methane, and the ash helps landfill break down more evenly.
In 8% of US states, bio-waste is actually fed into anaerobic digesters, where microscopic bacteria break it down into carbon and methane, which is captured and used as a biofuel.
As waste management gets more and more efficient, hopefully, all our states will share the same technology, and that will become the norm, but for now, check with your local authority so you know what happens to the waste you’re flushing away!
How to Use a Garbage Disposal Unit
Once you’ve got a garbage disposal installed, using it couldn’t be easier. Just flush your food waste down the plughole, flip a switch, and it does the rest. The macerated food waste is churned up with the wastewater from your sink and flushed down the drain.
They need to be plugged into the mains as all garbage disposals require a power source, but they are designed for continuous use, making them incredibly easy to use, install, and maintain.
What to Look For in a Garbage Disposal Feed
If you’re looking for a new garbage disposal, or upgrading to the best garbage disposal, make sure you’re buying the right one for your house.
Different garbage disposals are set up to cope with varying amounts of food waste, with some able to cope with commercial kitchen levels of waste, while some are designed for studio apartments where there is usually only one of two people’s worth of waste.
It’s time to get a new garbage disposal if your current unit gets frequently clogged, needs resetting regularly or odors are left behind. Those basic symptoms are usually a sign of a deeper problem so check for leaks and make sure the blades are chopping properly.
Continuous Feed vs Batch Feed Garbage Disposal
Continuous feed garbage disposal units are designed for constant use. They are much easier to use than batch feed garbage disposal units but need integrating into existing plumbing (this can be a positive and a negative).
Batch feed garbage disposals are better at coping with large amounts of kitchen waste and are operated by opening up the drum, filling it with your waste, and turning it on, which then flushes any waste out into the water.
These are best for big commercial kitchens, or large families who make mountains of food waste. For the average American homeowner though, a continuous feed is usually the fastest to install, the least costly, and the simplest to operate.
Best Garbage Disposal Motor Size
Garbage disposals are measured in horsepower (HP). ½ HP models are designed for smaller families, or one-person households where you will typically be flushing smaller amounts of waste, and usually softer waste like veg peelings, rather than left-over dinners.
1 HP models are designed to cope with heavier waste and can chop down most food, so for families with kids who never quite finish their plate they’ll be happy chopping up whatever is left over, and will usually last longer.
Other Features to Look for with Garbage Disposal
Garbage disposal units are basically just blenders, so there’s no such thing as a quiet garbage disposal, but the best garbage disposals have insulated chambers to dampen the sound.
While those features add to the cost, they are well worth having, especially if you’ve got guests over. For the best garbage disposal units, make sure to buy one with an anti-splash baffle, corrosion protection, or stainless steel blades.
They make it far easier to keep your sink clean, as well as clean the internal parts every month or so just increasing the lifespan of your machine.
For homes with septic tanks, you can also buy garbage disposals with enzyme reservoirs, which do need to be maintained but help break down food scraps further before they hit your septic tank, which helps prevent vermin and odors around the house.
Garbage Disposal Safety Guide
Obviously, a macerator stuck permanently under your plughole has some clear health and safety tips that come as standard, but just in case you need warning – don’t stick your hand down the hole full of spinning knives, it will hurt, and it will cause lasting damage.
Besides the obvious though, there are some steps to take to make sure your garbage disposal is installed and used safely:
- If you’re not a confident plumber, get a professional to install the unit
- Familiarize yourself with what can, and can’t be put down your particular garbage disposal
- Clean your disposal regularly with vinegar and baking soda to keep it clean, and odor free
- Sharpen the blades with ice cubes once a week
- Only ever use cold water. Hot water can damage your unit.
- Run water once the disposal has finished operating. Running water for 10-15 seconds after each use helps to elongate the life of your unit, and flush out the last bits of food waste.
- Fibrous vegetables like celery shouldn’t be put down the drain – they can cause clogs in any system
- Bone, grease, oil (including oil-based paints), latex and plastic should never be disposed of through a garbage disposal. They are damaging to the unit and the environment.

Clogs can happen for many reasons. It could be normal sludge, something too thick went down the drain or oil has hardened within the pipes. You can use a clog cleaner made for use in disposals.

1. Check the Garbage Disposal Unit

Just plug something else in and see if it works. If it doesn’t then the problem is not the disposal. You might want to check the breaker. If you have not found the problem then move on to resetting the unit.
2. Use Reset Button
Garbage disposals are made to be rather user friendly and repair friendly. It doesn’t take any complicated tools or knowledge to reset your garbage disposal.
All you have to do is look for the reset button, which is usually located on the bottom of the unit and bright colored. If it needs reset then the button will be sticking out. Simply push the button and you should have a working disposal.

Most companies have years of experience in repairing disposals and their plumbers are trained to determine the problem and get the machine fixed quickly.
