Types of Garbage Disposal

In the market, you will find different types of garbage disposals. Choosing the best type is the first step towards having an effective drain age system.

  • Continuous Feed Garbage Disposal

Continuous feed operation garbage disposals allow steady flow of waste foods into the system. The blades cut through food particles and you can keep washing down more and more of it. This works fast and you can complete tasks in the shortest time.

  • Batch Feed Operation Garbage Disposal

Batch feed operation works with the same principle as continuous feed. The waste foods are ground in the same manner by the action of blades which are powered by the motor. The unit is activated when the stopper is fitted. This is why it is called batch feed operation type. The food particles are ground in several lots unlike the continuous type.

  • Dishwasher Garbage Disposal

This type of garbage disposer can be linked to a dishwasher machine so that it grinds the waste matter from the dishwasher before sending it down the drains. The disposal can also work to grind wastes from the sink.

  • Septic System Garbage Disposal

Some garbage disposals are compatible with septic system. They work with properly-sized septic tanks and can be a great addition to the entire drainage system. Currently, you can find garbage disposals that have enzyme releasing microorganisms to aid in the waste degradation process.

How to choose the right garbage disposal

If you want to have a garbage disposal in your home, make a point of getting it right from the start. Once you choose the wrong device, no matter how good you do the subsequent procedures, you will not get the desired results. There are some things you need to remember when making the decision. Once you get the basics, you will get it right. One thing you should never forget is that a garbage disposer should be chosen basing on the needs of your home.

Motor Size

When choosing the motor size that you need at home, look at how busy your kitchen drains can get. The motors come with different power starting from 1/3 to more than 1 Horsepower. A 1/3 Horsepower motor will serve a small household well but if you wash down many food wastes, then consider going for a bigger size. A ½ Horsepower motor is good for an average household but it is good to go higher if you want the fastest performance. The small motors can burn easily when the load gets too much. A ¾ Horsepower motor has the capability to work through the toughest waste foods very fast. If the household is very big, then the food wastes are equally many and the sinks can be overloaded. You need a drainage system that can stomach all these starting from a multiple bowl sink to an efficient trap. The best supplement to the system will be a big motor size. The 1 Horsepower garbage disposal is good for such big households. This can cut through the toughest wastes and works best even with a big grind chamber.

Noise Level

The motor will obviously produce noise when grinding. However, with some advancements in the field, you expect a garbage disposal to work quietly; at least quieter than the initial devices. When you are buying a garbage disposal, you are free to test it and see how loud it can get. Imagine those sounds in your kitchen. The modern disposals from different manufacturers have silencing technology that works to reduce noise levels. This mostly involves sound insulation, especially around the motor which is the source of vibrations. The presence of such additions as sink baffles and anti-vibration connection pipes makes the silencing technique more effective.

Don’t get substandard. There are garbage disposals which cannot be heard unless you listen keenly. Some start with a thud then get silent thereafter. I bet you don’t want loud noises in the kitchen so that you are shouting all over to be heard.

Stainless Steel

Bring quality in your kitchen when you buy a garbage disposal made of stainless steel parts. You’ve seen stainless steel on many kitchen appliances; the reason is its good qualities. Thematerial is rust-resistant and will last long in functional state. Look for a disposal that has stainless steel grinding components. These can withstand a lot stress and will cut through many types of waste foods. Blades made of stainless steel give a good cut and the wastes will be ground finely. This makes them pass through the pipes without causing any problems. You will not see the drain clogging anymore.

A stainless steel grind chamber is also good because it resists rusting and corrosion. However, for the chamber, other materials can be good enough. Some disposals have glass-filed nylon chambers whereas others are plastic. A grinding chamber does not need to be limited to stainless steel.

Dishwasher Attachment

Do you have a dishwasher at home? Waste water from the dishwasher can clog your pipes. You have a chance to stop this when you install a garbage disposal that is compatible with the dishwasher machine. The attachment is not complicated. It involves connection with a pipe. The wastes from the dishwasher will be flowing to the disposal first where they are ground into small particles that can be washed down the drain lines very easily. Several models on the market have an allowance for this. Avoid frequent clogs by grinding every piece of waste food from all parts of the house. If you don’t have a dishwasher today, it is still safe buying a disposal with the attachment so that when you buy one in future, all you do is make the connection and you are good to go.

Batch Feed vs. Continuous Feed

Garbage disposals can have batch feed or continuous feed operation. Batch feed disposals are those that take the wastes in ‘batches’. Foods flow in portions and are ground then the next lot comes in. The operation involves first allowing water into the disposer then the waste foods. When the stopper is fitted into the flange, the system is activated. This means that you don’t need a wall switch. The automaticity makes operation and installation very easy. Because the stopper is fitted during functioning, there will be expulsion of the wastes from the grind chamber when the disposer is running. The grinding process is slower than the continuous feed because you have to wait for one batch to be ground before you can proceed with your tasks. The difference is not so big though.

A continuous feed operation allows wastes to keep flowing into the disposal as it grinds. Here, you have to activate and deactivate the system yourself by turning the switch on and off. A continuous feed disposal completes tasks very fast because you don’t have to wait for the grinding to be completed before allowing the next lot in as is the case with batch feed. You could have some food wastes expelled from the grind chamber but a splash guard takes care of this.

You will find both types of disposals in the market. Choose the one you like although if you want to finish grinding faster, the continuous feed will work well. The quality of grinding that they produce will also depend on the motor.

Extra Features

Some additions can improve the functioning of the garbage disposal. There are those that come with splash guards which help keep the sink clean and avoid the messy situations. Removable splash guards are better because you can withdraw and make wash it then fix it back. You might also like a disposer that comes with a power cord. The cord length should be considered. Short power cords will limit you to a certain position of installation. This however goes with the presence of an electrical outlet beneath the sink. If it is not available, you will have to plug the disposer into an existing power line. The number of grinding stages affects the fineness of the grind. How easy I it to install the garbage disposer? Make sure it has easy-to-install mechanisms so that replacements can be done easily.


Your home deserves a garbage disposal unit. This will relieve the drains of frequent clogs and you won’t have to spend much on maintenance. Get one today and have it correctly installed for the best results. Read through the best garbage disposal for septic system reviews in the preceding sections to find out what is best for your home.
