What’s the Difference Between Continuous Feed vs. Batch Feed Disposals?

Understanding the differences between continuous feed disposers and batch feed disposers is what will help you determine which option will work best for your household. Let’s take a closer look at what each type has to offer.

What is a Batch Feed Disposal?

Batch feed disposals are identical to the much more common continuous feed garbage disposal except for a few things:

Of the two types of garbage disposals, batch feed models are less popular; however, this does not mean that they are any less efficient. While continuous feed models start up with the simple flip of a switch, batch feed models require a few additional steps.

First you load up the batch feed garbage disposal like you would with any other disposal, then with the water running, you insert the stopper - the stopper is what triggers the switch that gets the unit’s motor up and running. The food waste is then ground down and washed down the drain. The primary downside to this model is that you must place the waste inside the garbage disposal before turning it on. If you are making a purchasing decision based upon convenience alone, then a continuous feed garbage disposal will win each time.

Continuous feed garbage disposals are currently the most popular type of garbage disposal in North America. Most of our recommended models are continuous feed.  Its popularity is due, in part, to how simple it is to use. Food is simply placed in the disposer, the unit is powered on (generally via a flip switch), and the disposer grinds up and disposes of the food waste.

Even while it is running, you can easily add more food waste to the waste disposer, which translates to faster cleanup times and an efficiently run kitchen. If you have large amounts of food waste to dispose of, being able to keep the disposal running means that you will get the job done faster.

These units require a minimal amount of maintenance, and cleaning them is a simple process. Modern garbage disposals are sold with multiple grinding chambers, which significantly reduces the chances that a clog will develop in your home’s plumbing, and different horsepower motors are available depending on the amount of grinding power your household requires. In terms of pricing, these units are more affordable than their batch feed counterparts.

For all of the benefits they have to offer, continuous feed garbage disposals are not without their cons. Depending on the specific brand you purchase, your unit may or may not come with a power cord, which means that you will have to purchase one separately or hire a professional plumber to hardwire the disposal.

Likewise, you must take into account that continuous feed food waste disposers have an open filler neck. There is always a slight risk that debris may come out while the unit is running, but most manufacturers do include a splashguard with their units, which solves this issue. If you have small children in your home, you will need to take precautions to ensure that they do not stick their hands into the garbage disposal’s opening.

For many homeowners, it can be tempting to fill a batch feed disposer’s grinding chamber with food waste and wait to grind it up until the chamber is full or he or she has the time to grind it. However, this creates a potential health hazard as the food waste begins to decompose. Not only does it attract bacteria, but it may also attract insects.

It should be noted that batch feed and continuous feed garbage disposals grind and dispose of food waste equally well. Batch feed models are available in the same horsepower and grinding chamber configurations as their continuous feed cousins; however, they do gain in advantage in ease of installation. Almost all batch feed models come with an included power cord, which means that most homeowners will be able to install the unit themselves – without having to hire a costly professional plumber.

Ultimately, continuous feed models will make your life easier, but which model you choose for your home is going to depend on three primary factors: safety, cost, and the amount of waste you routinely dispose of. Of these three factors, you will need to decide which is most important to you.
