Special types of garbage disposals

Sometimes you can’t purchase just any old garbage disposal and install it under your kitchen sink. Situations in which you should consider special types of garbage disposals are when: you have a septic tank, a deep or farmhouse kitchen sink, or when you want to connect your dishwasher to the waste disposal as well.

  1. Waste disposal for dishwashers
  2. Waste disposal for a septic system or septic tank
  3. Garbage disposal for a deep farmhouse sinks

In case you are looking for different types of garbage disposal systems, for instance, the different options for motors, mounts, and feeds. We also have a page about that, which you can explore here.

1. Waste disposal for dishwashers


Yes, it is possible to connect a dishwasher to your garbage disposal if the disposal unit has a connection for the dishwasher hose. But first, why would you want to connect your dishwasher to your food waste processor?

A dishwasher cleans your dirty dishes, cutlery, pots, and pans. And in this cleaning process, a lot of food waste is flushed down the drain. To prevent clogging of your drain pipes it is a good idea to grind the food waste with a food waste disposal. By connecting the disposal to your dishwasher the discarded wastewater goes through the garbage disposal and gets ground up before it is flushed away. Moreover, it is more convenient and space-efficient to connect your dishwasher hose to the garbage disposal instead of using all kinds of drain connector parts to bypass the disposal unit. Most garbage disposals today do have a dishwasher inlet but not all of them. So, especially, if you are looking for a budget-friendly disposal and you want to connect it to your dishwasher, don’t forget to make sure that that waste disposal has the necessary inlet.

2. Waste disposal for a septic system or septic tank

Can you use a garbage disposal if you have a septic system instead of the regular sewer system? A septic tank is a watertight tank that stores domestic sanitary wastewater underground and is most commonly used in areas where there are no connected sewerage systems. If your wastewater is stored in a septic tank it isn’t recommended to use just any normal garbage disposal unit. Why is that?

3. Garbage disposal for a deep farmhouse sinks

If you have a deep sink farmhouse sink in your kitchen it can be difficult to find a garbage disposal that fits in the limited cabinet space. Deep sinks or farmhouse sinks take up a lot of the cabinet space already so you need a compact garbage disposal that isn’t very tall.

So how tall or short does the disposal need to be? A garbage disposal (including the mount) should not be taller than the space between the lowest part of your sink and the floor of your kitchen cabinet, plus about 4 inches of clearance. This is so the disposal can be installed easily and so you can reach the bottom of the waste disposal system in case you need to unclog is manually with an Allen wrench later on.
