Is it necessary to have a Dishwasher Drain Hose to be connected to your Garbage Disposal even if I don't have a Dishwasher anymore? If not! How can I stop the Water from leaking out from that hole? HELP PLEASE! Thank You!

WHAT? You can't figure out how to close the little hole? Home Depot sells a rubber cap for that purpose. You can also cut the hose and get a rubber stopper in the HD hardware section. Inthe meantime,stuff a wad of paper towel in the hole and cover it with duct tape

Cut about a two inch long piece of the 7/8" hose which used to connect to the disposal. A 3/4 copper plug fits inside this exactly. Reattach hose to disposal. ( use clamps on both ends), good luck.
