Continuous Feed vs Batch Feed

Continuous feed disposals are easy to use than batch feed. Also, speed is a big benefit of continuous deed disposals. You only need to turn on the continuous feed disposals with a switch.

Once you are done with your task, you can turn off the switch. Continuous feed disposals are more popular because of their speed and ease of use. However, there are some safety issues with the continuous feed garbage disposals.

When it comes to batch feed disposals, they are safer than continuous feed. The batch feed disposals will only start when the stopper is there. This stopper will work as a barrier so your children cannot put a finger in it.

The one other benefit is that the batch feed disposals are quiet. Because the stopper covers the mouth of the disposer, that’s why it reduces unwanted noise. But, the batch feed garbage disposals are time-consuming.

In batch feed, you have to put the waste into the batches. The more food waste, the more time you have to spend to put the waste. The batch feed disposals are large. It can be an issue if you have a small septic tank.

If you want affordable and convenient garbage disposal then the continuous feed is a great choice. However, small families with children should go for batch feed. But, make sure you have a big septic system and sink for batch feed.

Performance of garbage disposal

The performance of disposal usually depends on the motor. There are 1/3, ½, ¾, and 1 horsepower motors available in residential garbage disposals.

The 1/3 horsepower motors are the weakest motors for garbage disposals. However, they are affordable and work well for small families. You can also choose 1/3 HP motors if you have small space.

But we will recommend the ½ HP motors because they are enough to power full for small and big families. If you have six members family, then the ¾ or 1 HP motor is necessary.

These motors are the perfect deal for fibrous vegetables. It is also useful if you are organizing any parties at your home. These are compatible with heavy use and different kinds of waste.


Make sure the garbage disposal you choose should be easy to install. This feature is not necessary, but it can save you a few dollars that you spend on the plumber. And if you face any small issues in the future then you can also solve them by yourself.

Some garbage disposals in the market are complicated to install even for experienced plumbers.

After-sale services

If you want to purchase disposals from another brand, then make sure they provide at least one year warranty. In the warranty period, you do not have to pay extra charges if any issue occurs.

Material and other features

The grinding chamber of disposal should be made from stainless steel. Stainless steel is a durable material and water-proof a well. Also, choose a disposal that has an anti-jamming feature. The best garbage disposals for septic must have this feature.

Some high-quality garbage disposals come with an auto-reverse feature. This feature detects jam and reverses grinding to prevent frequent jams. Some premium models come with multiple grind stages.
