Garbage disposal

Water will not pass through the garbage disposal unless the garbage disposal is running

Pouring 2 qts into the non-running disposal takes how long to drain?

Sounds like your stack vent could be clogged.

No amount of water will drain, unless the garbage disposal is turned on and operating. The garbage disposal works fine. In a couple days, I plan to disconnect the garbage disposal and inspect it's inside and the drain pipe. I am confident that I'll find the problem. I was hopping that I would not have to do any disconnecting.

Do what "Yoyizit" stated. Pour two quarts of water into the side with the disposer, let it sit, and time how long it takes to drain. After this drains, I would remove the "P" trap only part of the drain, put a bucket/something under the open pipe from the disposer, and pour another two quarts into the sink to see how long it takes for the water to run out. IF the water runs out quickly, I bet it does, then the problem is beyond the "P" trap. Now "Mr. Chips" comes into play. Could be a clogged vent stack. Could be something in the drain after it enters a wall. Do you have a dishwasher? I've found a few that the lines were coated with a gummy/soapy material creating a small internal diameter=slow drainage. This was due to dishwasher soap(s). David

don't waste your time taking disp apart. your problem lies elsewhere. poss vent as Mr C. suggests. post in the plumbing section see what they say. then report back so we may be enlightened.

i really thinks it's clogged vent. When you run the disposal, the mechanical action of the motor and blades gives you enough force to drain the water, with it off and a clogged vent, water just sits. if there was a problem with disposal itself or a clogged trap the water would sit even if powered on
