How to Open Dishwasher Drain on Garbage Disposal?

Almost all garbage disposals come with a dishwasher inlet to connect the dishwasher. There is a knockout plug to cap off the inlet so that the water and food content does not back up. In case, you want to connect a dishwasher to a dipsosal unit, removing this plug is mandatory. 

  • Look for the dishwasher inlet, which is located on the side where the disposal outlet is.
  • Place a screwdriver inside the dishwasher inlet hole and tap it using an everyday hammer.
  • You can knock it with a little force until it falls inside the disposal unit. 
  • Shine a torchlight inside the garbage disposal and remove the plug using a plier. 

You must open the dishwasher drain or take out a knockout plug before mounting the garbage disposal. Otherwise, it may be difficult after that as there is less space underneath the kitchen sink. Also, you cannot plug in the dishwasher without removing the plug. If you do it, backup content would fill the kitchen.

Why Does the Dishwasher Drain into the Garbage Disposal?

The dishwasher drains into the garbage disposal to avoid unnecessary backing into it and the kitchen cabinet. The other reason is that the dishwasher may contain food particles in the wastewater, which will catch in the disposal chamber when draining in it instead of drain pipes for further grinding. 

How Does Garbage Disposal Affect Dishwasher?

The dishwasher usually uses no separate plumbing lines, instead, it is connected with the same pipes to which the garbage disposal is installed. In any case, disposal pipes become clogged, and the consequence runs a long way to the disposal unit and dishwasher damage.

Don’t put dishwasher pods in the garbage disposal. They’re made for dishwashers, not disposals, and might not dissolve well. The ingredients could also harm the disposal. Follow the instructions for both the dishwasher pods and the garbage disposal to avoid problems and damage.
