Batch Feeding Method

Installing this kind of trash disposal during your kitchen renovation is thought to be safer. Before you turn on this kind of unit, you’ll fill it with water and cover it. It may take some time to empty the batch if the unit becomes full. If you forget to add waste, you’ll have to wait until the current batch is finished before adding it and running it again. It’s impossible to inadvertently drop anything inside since you cover it before turning it on.

System of Continuous Feeding

When you switch on this system, you don’t need to cover it since it will operate constantly. When it’s on, you’ll have to keep your water running all the time, which may waste a lot of water.
