I think you were correct on going up the vent. Giving it another shot and if it doesn't work then I'll call a pro. I'm using an old hand snake with a vice grip for leverage. Not dangerous, just hard to get the feel you mentioned. Thanks again for the advice!
When running the snake it would clear and then block again after another foot or so. Then it really opened up for the last 10 feet or so and I thought I was home free. When I couldn't get the water to stop coming back up through the disposal then I realized the water coming up the air vent...
I have a clogged kitchen sink that is becoming a nightmare. I removed the disposal and pipes under the sink. I ran a snake roughly 25ft and all seemed clear. Now when I run the water and disposal its coming out of the roof overflow pipe. I ran out of snake. Does this mean that I have a clog...
