Garbage disposal knockout plug

This seems like a really dumb question... but I'm prepping to install a new dishwasher, and all instructions I have read on the web say to knock out the disposal plug before installing it so it can be removed from the top of the disposal. Our disposer is already installed... do I have to remove it, or will I be able to fish it out from the sink?

You should remove it. It's just plastic, so it will probably eventually get ground up, but you don't want to damage your new disposal.

Here's a way to get it out without removing the disposal: (First, unplug the disposal or kill the circuit breaker). If you have any plumber's putty or sonething sticky like that hanging around (playdough? wax? double-sided tape?) put a little ball on the end of a screwdriver and carefully reach it down there and "stick" the plug and lift it out.

Do you have a long pair of thongs they use for cooking and a small flashlight??

That will do the trick I have used them several times on stuff accidental put down there that won't grind up.

Stuff the dry food waster grinder with a continuous length of paper towling to just below the level on the inlet, knock out the plug, retrieve it form the top of the paper, then fish out the paper.

Take a screwdriver, knock the plug in, suck it out with your shop vac. And if you don't have a shop vac, you should.
