How to unclog an Insinkerator 444 Garbage Disposal.
If the disposal is working, but the water and waste wont go down, you have a clogged disposal chamber, or a clogged disposer drain pipe. The first step is to use a plunger. 9 times out of 10, the plunger will do the trick. Fill the garbage disposal up until water starts to fill the kitchen sink. Then with the plunger firmly sealed at the mouth of the disposal, pump it up and down several times until you feel a suction building, and then yank the plunger up and hopefully dislodge the clogged particles. If this doesnt work, then you will have to remove the drain pipe exiting the side of the disposal and clean it out with a screwdriver or something long and skinny.
