Garbage Disposer Batch Feed versus Continuous Feed
The garbage disposer comes in two basic varieties, batch feed and continuous feed models. The continuous feed style is, by far, the most common. The model you choose is really a matter of personal preference. To learn more about the two styles of waste disposals and to learn their advantages and features, see the details below.
Continuous Feed Garbage Disposer
The continuous feed disposer model runs only switched on. The switch can be a regular wall switch or a counter top "air switch" ( a non-electrical switch safe for wet environments). The disposer is operated by turning on the cold water, switching on the disposer and dropping suitable kitchen debris in the drain hole in the sink. After the debris has been thoroughly ground up, turn off the disposer and then a few seconds later turn off the water.
The main advantage of this disposer over a batch feed model is that you can continuously to feed in garbage until you are done.
The key disadvantage of this model is that it is more dangerous. It is possible to turn it on while reaching into the drain. There is risk of things, like silverware, falling in while it is operating.
Batch Feed Garbage Disposer
A batch feed disposer operates very similarly as a continuous feed except there is no switch to operate it. Instead the disposer is switched on by placing the drain plug in place and turning it. You start by placing suitable kitchen waste into the disposer, turn on the cold water and install and turn the drain plug. When it has finished grinding , you stop the disposer by turning the drain plug the other way.
The chief advantage with the batch feed disposer is safety. It cannot operate without the drain plug, and so it will not operate while reaching into the drain, nor can items fall into the disposer while it is operating.
The chief disadvantage is the ability to place only a small amount of waste into the disposer at a time. It must be repeatedly loaded and operated if you have even of moderate amount of kitchen waste. Another disadvantage is the batch feed models are less common, possibly making it more difficult to find one. Although all of the major manufacturers offer one or more batch feed disposer. Also, batch feed models are typically only available in higher end models, and so they are not generally available amongst the lower priced models. Finally, since it will not operate without the manufacturer's drain cover, it cannot be operated if your drain cover is lost or damaged.
