Installing A Garbage Disposal

The first thing you need to do before installing a garbage disposal in an area with this type of system is to check with the water authority or the waste management company in your area.

You'll also have to consider the type of sink you have. It's much more straightforward to install garbage disposal under a single sink than under a double sink.

If you have a double sink, the easiest and most effective way to pipe in the disposal is to run the discharge tube of the disposal directly to a tee that is located below the other sink. This will allow the disposal to connect to both sinks at once. For the drain to function properly, the tube needs to be lowered by about a quarter of an inch.

Size And Storage

Check the dimensions of your sink and the space below it to ensure that a garbage disposal will fit before making the purchase. The length of various disposals can range anywhere from ten to fifteen inches. Differences in width and depth are also very important aspects to consider.


Garbage disposals can be found with a variety of horsepower ratings. The higher the power rating, the more effective the grinding capability and the better the sound insulation the disposal will provide. This depends on the requirements of your household, the size of your family, and whether or not you need to grind tougher food particles. 


Determine the material that the pipes in your home are made of. If you have white PVC (polyvinyl chloride) pipes, food debris would be less likely to become lodged in them due to the slippery nature of the pipes. Old cast-iron drainpipes are more prone to clogging than newer plastic or PVC ones. 

Septic System

Inquire about your septic system's ability to handle additional food waste before you install a garbage disposal. If you install a garbage disposal in your kitchen, the quantity of waste that your septic tank must be able to handle will be greatly increased. Your tank capacity may need to be increased because of the amount of food waste you generate.

Batch-Feed or Continuous Feed

Batch-feed and continuous-feed are the two main types of garbage disposal.

With batch-feed models, instead of putting scraps of food down the garbage disposal as it is running, you put scraps of food into the disposal one batch at a time, then place a stopper over the drain opening to turn the disposal on.

With continuous-feed models, these machines are activated by a switch and can process vast volumes of food while operating.

Is It Better To Throw Food Away Or Use A Garbage Disposal?

Using a garbage disposal is better than throwing away food in your trash. This is because of the fact that the disposals reduce the amount of greenhouse gases emitted into the atmosphere, and clean energy can be collected. 

The decomposition of food waste in the trash, which is then transported to a landfill, results in the production of methane gas, a strong greenhouse gas that is far more powerful than carbon dioxide.

On the other hand, food scraps that are transported to treatment facilities are broken down by anaerobic digesters. Methane gas created during the decomposition process is collected and converted to either electricity or biofuels.

What Can I Use Instead Of A Garbage Disposal?

The best alternative to a garbage disposal is eventually not needing one, which means reducing your food waste. Composting, on the other hand, is the best course of action to take if you are unable to avoid throwing away food.

Composting outside or making vermicompost inside your home is an option for those who have the space. Sink strainers are another option for catching kitchen scraps. Feeding food scraps to animals can also be an option, but you should exercise caution when choosing what you feed the animals. 

Is Garbage Disposal Bad For Plumbing?

Garbage disposals are generally not bad for plumbing, but they can be if you don’t use them properly. Plumbers may have to deal with clogged pipes as a result of a buildup of debris. 

Always make sure to use running water when operating your garbage disposal. This will assist in the movement of particles into the machine. It is recommended to use cold water to solidify any grease or oils that may go down the pipes. These substances will then be pulverized to make passage through the pipes easier.

Food waste that is capable of being liquefied and biodegradable is the type of waste that can be put down disposals without causing obstructions in the drainage pipes. 

Is Garbage Disposal Necessary For A Dishwasher?

It's not necessary to have a garbage disposal installed in conjunction with a dishwasher. You can manually rinse the dishes before putting them in the dishwasher. The majority of modern dishwashers also come equipped with their own built-in garbage disposals.

It is required that dishwashing machines be linked to an air gap that is located between the kitchen sink and the dishwasher. Through the use of an air gap, polluted water is prevented from flowing backward into the sink or dishwasher.

In Conclusion

The installation of garbage disposals is one of the most remarkable improvements that can be made to a kitchen. In addition to this, they offer a more environmentally friendly means of getting rid of food waste. Have fun going shopping for the garbage disposals you've selected based on the information we provided. Go ahead and install it in your sink.
